Red Sox 2024 minor-league saves leader signs with American Association team

Former Red Sox minor-league reliever Felix Cepeda has signed with the Sioux City Explorers of the American Association, per the independent league’s transactions log.

Cepeda, 24, paced both the Red Sox organization and the Eastern League with 14 saves in 18 opportunities at Double-A Portland last season. The right-hander posted a 5.57 ERA (5.19 FIP) with 37 strikeouts to 20 walks in 30 relief appearances (42 innings) for the Sea Dogs. Opposing hitters batted .271 against him.

Despite leading the Eastern League in saves, Cepeda struggled in several other areas. Among the 135 pitchers league-wide who threw at least 40 innings last year, the righty ranked 87th in walk rate (10.3 percent), 101st in strikeouts per nine innings (7.93) and walks per nine innings (4.29), 115th in swinging-strike rate (10.5 percent), 117th in strikeout rate (19 percent), 119th in batting average against, 121st in xFIP (4.60), 124th in WHIP (1.57), 127th in ERA, and 128th in FIP, according to FanGraphs.

Cepeda, who hails from the Dominican Republic, originally signed with the Red Sox for $40,000 as an international free agent coming out of Bonao in July 2017. The 6-foot-3, 210-pound hurler made his professional debut the following June and steadily worked his way up the organizational ladder. He actually enjoyed somewhat of a breakout 2023 campaign that saw him pitch in the Arizona Fall League and earn first-time SoxProspects.com All-Star honors.

Though he came into the 2024 season ranked by SoxProspects.com as the No. 48 prospect in Boston’s farm system, Cepeda was unable to replicate the same kinds of results he produced in 2023. It should be noted that he spent time on the injured list in May and August before reaching minor-league free agency in November. He then allowed 11 runs (eight earned) in eight outings (eight innings) for the Algodoneros de Guasave of the Mexican Pacific League this winter.

Now, Cepeda — who does not turn 25 until July — will presumably look to re-establish himself in the American Association with the hopes of returning to affiliated ball sometime in the future. In the past, he featured a 95-96 mph fastball that got up to 98 mph and complemented it with a mid-80s slider and an upper-80s changeup.

Red Sox relief prospect Felix Cepeda to begin 2024 season at Double-A Portland

One of the Red Sox’ more unheralded relief prospects will be getting his first taste of competition in the upper-minors to begin the 2024 season.

Felix Cepeda has been assigned to Double-A Portland, per his Instagram account. The Sea Dogs open their season with a three-game series against the Hartford Yard Goats at Hadlock Field beginning Friday night.

Cepeda, 23, split the 2023 campaign between Low-A Salem and High-A Greenville, so this serves as a promotion of sorts. The right-hander posted a 2.38 ERA and 3.45 FIP with 60 strikeouts to 29 walks over 33 total relief appearances (53 innings) in which he held opposing hitters to a .194 batting average against.

After spending all of 2022 at Salem, Cepeda returned there for the start of the 2023 season. The Dominican-born righty forged a 3.03 ERA (3.61 FIP) with 39 punchouts to 23 walks in 19 outings (32 2/3 innings) for Boston’s Carolina League affiliate before earning a promotion to Greenville in mid-July. With the Drive, he pitched to a 1.33 ERA (3.19 FIP) to go along with 21 strikeouts to just six walks over 14 appearances (20 1/3 innings) to close out the regular season. He then made three straight scoreless appearances in the playoffs (including the clincher) to help Greenville take home its first South Atlantic League title since 2017.

Altogether, it was a solid showing for Cepeda in 2023. Among the Red Sox minor-leaguers who eclipsed the 50-inning threshold in the regular season last year, Cepeda ranked 20th in strikeouts per nine innings (10.19), 16th in strikeout rate (26.4 percent), third in batting average against, ninth in WHIP (.125), sixth in line-drive rate (17.2 percent), 15th in groundball rate (43.8 percent), 18th in groundball rate (13.7 percent), fourth in ERA, sixth in FIP, and 19th in xFIP (4.31), per FanGraphs. He also lowered his walk rate from 15 percent to 8.1 percent after making the jump from Salem to Greenville over the summer.

Even though he had logged a career-high in innings pitched by the time the Drive were crowned South Atlantic League champions at Fluor Field in late September, Cepeda’s season was not over. Like several other Red Sox prospects, Cepeda headed out west in early October to play in the Arizona Fall League. He proceeded to appear in eight games for the Glendale Desert Dogs, allowing eight runs (six earned) on eight hits, three walks, and six strikeouts across eight frames of relief.

Coming off an eventful 2023 that resulted in him being named a SoxProspects.com All-Star for the first time, Cepeda reached another milestone this spring by getting into three Grapefruit League games last month. He yielded a total of two runs (both of which came in the same outing) on four hits, two walks, and two strikeouts over 1 1/3 innings while also recording a save against the Twins at JetBlue Park on March 23.

Cepeda, who does not turn 24 until July, is currently regarded by SoxProspects.com as the No. 48 prospect in Boston’s farm system, which ranks 20th among pitchers in the organization. Originally signed for $40,000 as an international free agent coming out of the city of Bonao in 2017, Cepeda now stands at 6-foot-3 and 210 pounds. He throws from a high three-quarters arm slot and primarily operates with a two-pitch mix that consists of a 95-96 mph fastball that tops out at 98 mph and an 83-86 mph slider that features 10-to-4 break.

In Portland, Cepeda figures to join a bullpen that includes the likes of Alex Hoppe (once healthy), CJ Liu, Christopher Troye, and Ryan Zeferjahn, among others. It is also worth noting that Cepeda can become eligible for minor-league free agency after the 2024 season, so he will — in essence — be pitching for a new contract this year.
