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.
