Red Sox sidearm prospect Isaac Coffey named Double-A Portland’s Pitcher of the Year

Red Sox pitching prospect Isaac Coffey has been named Double-A Portland’s Pitcher of the Year, the Sea Dogs announced prior to their season finale against the Binghamton Rumble Ponies at Hadlock Field on Sunday.

Coffey, 24, appeared in 24 games (made 21 starts) for the Sea Dogs this season. The sidearming right-hander posted a 3.17 ERA and 3.81 FIP with 148 strikeouts to 51 walks over a team-leading 113 2/3 innings of work. That includes a 1.42 ERA (2.59 FIP) with 56 strikeouts to eight walks in six outings (31 2/3 innings) after the calendar flipped from July to August.

Among 35 qualified pitchers at the Double-A level in 2024, Coffey ranked second in strikeouts per nine innings (11.72) and strikeout rate (30 percent), fifth in batting average against (.215), seventh in ERA, 11th in WHIP (1.23), 12th in FIP, and 14th in xFIP (3.90), per FanGraphs. While the strikeout numbers are impressive, Coffey also ranked 28th in walk rate (10.3 percent) and 29th in walks per nine innings (4.04) while hitting more batters (25) than anyone else at his level.

Coffey just put the finishing touches on his second full professional season after originally being selected by the Red Sox in the 10th round of the 2022 amateur draft out of Oral Roberts. The California native received a modest $7,500 signing bonus at that time and is now regarded by SoxProspects.com as the No. 58 prospect in Boston’s farm system, which ranks 30th among pitchers in the organization.

Listed at 6-foot-1 and 205 pounds, Coffey threw from a three-quarters arm slot as a two-way player in college but has since settled in as a sidearmer. As noted in his SoxProspects.com scouting report, the athletic righty operates with a four-pitch mix that consists of an 88-90 mph fastball that tops out at 92 mph, a 76-78 mph changeup that is considered his best secondary offering, an 82-84 mph sweeping slider, and a newly-implemented cutter.

Should he remain with the Red Sox through the winter, Coffey — who does not turn 25 until next June — is projected by SoxProspects.com to make the jump to Triple-A Worcester in 2025. A lack of velocity limits his upside, but he still has intriguing potential moving forward.

How did Red Sox pitching prospect Isaac Coffey fare in first full pro season?

Of the 13 pitchers the Red Sox drafted in 2022, no one pitched more innings in their first full professional season than 10th-round selection Isaac Coffey.

Coffey, the 309th overall pick in the 2022 amateur draft out of Oral Roberts, received a modest signing bonus of $7,500 and made just two relief appearances in the rookie-level Florida Complex League as part of his pro debut. The right-hander then broke camp with High-A Greenville last spring to kick off his 2023 campaign.

In 11 starts for the Drive, Coffey posted a 2.83 ERA and 3.90 FIP with 83 strikeouts to just 11 walks over 60 1/3 innings of work in which he held opposing hitters to a .223 batting average against. He recorded three double-digit strikeout games in that stretch before earning a promotion to Double-A Portland in late June.

Coffey debuted for the Sea Dogs at Hadlock Field on his 23rd birthday (June 21) and put together one of his shortest outings of the year, allowing four runs over the first two-plus innings of a 5-4 loss to the Reading Fightin Phils. He rebounded to the tune of six scoreless, three-hit frames in a winning effort against the New Hampshire Fisher Cats eight days later and wound up producing a 3.92 ERA (4.93 FIP) with 72 strikeouts to 23 walks in 12 total appearances (11 starts) spanning 57 1/3 innings with Portland.

Among the 106 hurlers who accrued 50 or more innings in the Eastern League last season, Coffey ranked 13th in strikeouts per nine innings (11.3), 44th in walks per nine innings (3.61), 20th in strikeout rate (28.7 percent), 42nd in walk rate (9.2 percent), 20th in batting average against (.215), 21st in WHIP (1.20), 47th in swinging-strike rate (13.1 percent), 45th in ERA, and 48th in xFIP (4.15), per FanGraphs.

Altogether, Coffey went 11-6 with a 3.37 ERA (4.40 FIP) and 155 strikeouts to 33 walks in 23 outings (22 starts, 117 2/3 innings pitched) between Greenville and Portland. For his work with the Drive specifically, he was named a 2023 South Atlantic League All-Star alongside teammates Blaze Jordan and Roman Anthony.

A former two-way player in college, Coffey stands at 6-foot-1 and 205 pounds. The California native throws from a deceptive sidearm slot and — as noted in his SoxProspects.com scouting report — operates with a three-pitch mix that consists of an 88-90 mph fastball that tops out at 91 mph, a 77-79 mph slider that features 10-to-4 break, and an 83-84 mph changeup.

As for how his unique delivery came into existence, Coffey explained to FanGraphs’ David Laurila last June that it dates back to his early days at Oral Roberts, where — in addition to pitching — he saw limited playing time at both middle infield positions.

“I was always a three-quarters guy, never straight over the top, and in my freshman year I had 14 starts while also playing some third base,” Coffey said. “Then, in my junior year [Coffey’s sophomore year coincided with the pandemic], I was fielding ground balls at third base and kind of throwing it over to first sidearm. Doing that felt natural. Our pitching coach saw that and was like, ‘Hey, let’s get you on the mound and play with some different arm slots.’ We did that, dropping way down to going higher up, and settled on the where I’m at right now. It felt comfortable, and my velo and movement both ticked up from where they had been.”

Coming into his age-24 season, Coffey is currently regarded by SoxProspects.com as the No. 44 prospect in Boston’s farm system, which ranks 18th among pitchers in the organization. Barring a trade, he is projected to return to Portland’s starting rotation this spring.

Because he does not light up the radar gun, Coffey will need to show signs of improvement when it comes to handling more mature hitters in the upper-minors. He was solid with the Sea Dogs during the latter half of the 2023 season, but the Red Sox may be looking for more when it comes to evaluating Coffey’s development and future as a starter or reliever.

To that end, Coffey also told Laurila over the summer that he would be willing to do “whatever they want me to do” as it pertains to his future role and potential path to the big-leagues.

“I’ll dive into that role as best as I can,” said Coffey. “Right now it’s being a starter. It’s what I’ve always done. I came out of the ‘pen once in high school and not at all in college. I threw two innings in the [Florida Complex League] after I got drafted, but that’s it as far as relieving. But again, whatever they want in the future, I’ll dive right into it.”

Red Sox to promote pitching prospects Isaac Coffey, Hunter Dobbins to Double-A Portland

The Red Sox are promoting pitching prospects Isaac Coffey and Hunter Dobbins from High-A Greenville to Double-A Portland, according to MassLive.com’s Christopher Smith.

Coffey, who turns 23 on Wednesday, has posted a 2.83 ERA and 3.92 FIP with a South Atlantic League-leading 83 strikeouts to just 10 walks in 11 starts (60 1/3 innings) for the Drive this season. The right-hander fanned eight over 5 2/3 frames in his last time out against the Greensboro Grasshoppers at Fluor Field this past Thursday.

Among qualified pitchers in the South Atlantic League, Coffey ranks third in strikeouts per nine innings (12.38), second in strikeout rate (34.4 percent), second in walks per nine innings (1.49), second in walk rate (4.1 percent), 10th in batting average against (.222), third in WHIP (1.01), seventh in swinging-strike rate (14.8 percent), 10th in ERA, 13th in FIP, and first in xFIP (2.78), per FanGraphs.

Coffey was selected by the Red Sox in the 10th round of last year’s draft out of Oral Roberts. The California native signed with the club for a mere $7,500 yet is currently regarded by SoxProspects.com as the No. 51 prospect in Boston’s farm system, which ranks 22nd among pitchers in the organization.

Standing at 6-foot-1 and 205 pounds, Coffey throws from a sidearm slot and operates with a four-pitch mix that consists of an 88-90 mph fastball that tops out at 91 mph, a 77-79 mph slider that features 10-to-4 break, and an 83-84 mph changeup that is considered to be a work in progress. He becomes the second member of the Sox’ 2022 draft class to make the jump from Greenville to Portland this season, joining fourth-rounder Chase Meidroth.

Dobbins, meanwhile, has forged a 2.63 ERA and 2.52 FIP with 44 strikeouts to just five walks in seven starts (41 innings) for the Drive this season. The 23-year-old righty also struck out eight across six two-run frames in his last time out against Greensboro this past Friday.

Among the 57 South Atlantic League pitchers who have accrued at least 40 innings to this point in the 2023 campaign, Dobbins ranks first in walks per nine innings (1.10) and walk rate (3.1 percent). He also ranks 20th in strikeout rate (27.3 percent), fourth in WHIP (0.95), and sixth in swinging-strike rate (16.8 percent) after not making his first start of the year until May 7.

Dobbins was selected by the Red Sox in the eighth round of the 2021 amateur draft out of Texas Teach. After undergoing Tommy John surgery earlier that spring, the Lone Star State native signed with Boston for $197,500 and did not make his professional debut until last July. He currently is not rated by SoxProspects.com as one of the top pitching prospects in the system.

Listed at 6-foot-2 and 185 pounds, Dobbins — who turns 24 in August — throws from a high-three-quarters arm slot and works with a four-pitch mix that consists of a 91-94 mph fastball that tops out at 96 mph, a 74-78 mph curveball, an 83-85 mph circle changeup, and a high-80s slider that is rarely used.

Both Coffey and Dobbins figure to join a starting rotation mix in Portland that includes C.J. Liu, Brian Van Belle, Sterling Sharp (who is currently on the injured list), Grant Gambrell, and Wyatt Olds. The Sea Dogs open a six-game series against the Reading Fightin Phils at Hadlock Field on Tuesday night.

Red Sox pitching prospect Isaac Coffey strikes out 11 yet again in latest start for High-A Greenville

For the second straight outing and the third time in his last five starts, Red Sox pitching prospect Isaac Coffey recorded 11 strikeouts for High-A Greenville on Thursday night.

Going up against Rome on the road at AdventHealth Stadium, Coffey struck out 11 and did not walk a single batter over six scoreless, three-hit innings. The right-hander finished with 87 pitches (64 strikes) and induced 21 swings-and-misses. He also retired the final eight hitters he faced as the Drive went on to defeat the Braves by a final score of 6-2.

Coffey, who was credited with the winning decision, improved to 3-2 on the year. The 22-year-old has posted a 2.89 ERA and 4.64 FIP with 61 strikeouts to seven walks over eight starts spanning 43 2/3 innings of work for Greenville this season.

Following Thursday’s performance, Coffey now leads qualified South Atlantic League pitchers in strikeouts. He also ranks second in strikeouts per nine innings (12.57), second in strikeout rate (35.1 percent), first in walks per nine innings (1.44), first in walk rate (4.0 percent), ninth in batting average against (.217), second in WHIP (0.78), seventh in swinging-strike rate (14.9 percent), fourth in ERA, 13th in FIP, and first in xFIP (2.91), per FanGraphs.

Coffey, who turns 23 next month, was selected by the Red Sox in the 10th round of last year’s amateur draft out of Oral Roberts, where he was a two-way player. Since signing with Boston for just $7,500, though, the California native has been used strictly on the mound.

As noted in his Baseball America scouting report from before the 2022 draft, Coffey “will not light up the radar gun, but he has the ability to spot his deceptive 89-91 fastball from a low three-quarter slot.” The 6-foot-1, 205-pound hurler also “does a fine job spotting up his slider-changeup mix to attack both left-handed and right-handed hitters.”

Considering how much success Coffey has enjoyed at the High-A level as of late (1.96 ERA in four May starts), one has to wonder if the righty could soon be in line for a promotion to Double-A Portland. That in itself would represent a new challenge for a young pitcher who is seemingly having his way with the opposition right now.

Red Sox select Oral Roberts right-hander Isaac Coffey with 10th-round pick in 2022 MLB Draft

With the 309th overall pick in the 2022 MLB first-year player draft, the Red Sox selected Oral Roberts University (Tulsa, Okla.) right-hander Isaac Coffey.

Not related to second-round selection Cutter Coffey, Isaac was not ranked by Baseball America or any other major publication as one of the top pitching prospects in this year’s draft class.

After being named Summit League Pitcher of the Year in 2021, Coffey posted a 3.77 ERA and 0.96 WHIP to go along with 78 strikeouts to 16 walks over 15 starts spanning 88 1/3 innings of work for the Golden Eagles this season.

Coffey, 22, hails from Goleta, Calif and possesses a fastball that sits between 88-91 mph. The 6-foot-1, 205-pounder was a two-way player in college, but seems solely focused on pitching now since he only made 33 trips to the plate as a junior this spring.

The Red Sox last drafted a player out of Oral Roberts in 2005, when they took left-hander Matt Hancock in the 27th round. Coffey, meanwhile, becomes the sixth college arm Boston has taken in this year’s draft, joining the likes of Dalton Rogers, Noah Dean, Alex Hoppe, Caleb Bolden, and Jonathan Brand.

The recommended slot value attached to the 309th pick in the 2022 draft comes in at roughly $149,900. The Sox will have until August 1 to sign Coffey and the rest of their draft selections.

That concludes Day 2 of the MLB Draft. The third and final day of the draft will consist of rounds 11-20, meaning the Red Sox have 10 more picks to make. Day 3 begins at 2 p.m. eastern time.
