When thinking about which Red Sox prospects broke out the most last year, outfielder Roman Anthony probably comes first to mind, and rightfully so. On the pitching side of things, though, that distinction might belong to none other than Yordanny Monegro.
Entering the 2023 campaign, Monegro was not viewed by outlets like Baseball America as one of the top pitching prospects in Boston’s farm system. After spending all of 2022 in the Florida Complex League, the 21-year-old right-hander repeated at the Sox’ rookie-level affiliate to kick off his third professional season last June.
Monegro made just three starts for the FCL Red Sox and dominated, allowing two earned runs on five hits, four walks, and 20 strikeouts over 15 innings in which he held opposing hitters to a .102 batting average against. As such, he was named the Florida Complex League Pitcher of the Month for June, though he earned a promotion to Low-A Salem before the calendar had even flipped to July.
Facing full-season competition for the first time as a pro, Monegro picked up where he left off by striking out a career-high of 11 over five scoreless innings in his Salem debut on June 25. He tied that career high again in August and finished with a 2.43 ERA — as well as 60 punchouts to 17 walks — in nine starts (40 2/3 innings) for the Red Sox before making the jump to High-A Greenville in the late stages of the summer.
Yet again, Monegro impressed in his first outing with a new affiliate by taking over for the rehabbing Zack Kelly in the second inning and fanning eight Brooklyn Cyclones across five scoreless frames at Fluor Field on September 1. The righty did not fare as well in his final start of the regular season eight days later, but he made up for it by picking up the win against the Hickory Crawdads in the second and final game of the South Atlantic League division series on Sept. 14. The Drive then swept the Hudson Valley Renegades in the championship series to take home their second SAL title in franchise history and first since 2017.
All told, Monegro went 6-3 with a 2.06 ERA and 93 strikeouts to 26 walks in 14 appearances (13 starts) spanning 65 2/3 total innings of work between the FCL, Salem, and Greenville last year. Among his peers in the Red Sox organization who also eclipsed the 60-inning threshold in 2023, Monegro ranked third in strikeouts per nine innings (12.75), 10th in walks per nine innings (3.56), second in strikeout rate (34.6 percent), 11th in walk rate (9.7 percent), second in batting average against (.194), second in WHIP (1.10), 12th in line-drive rate (21.3 percent), fifth in groundball rate (48.9 percent), and first in swinging-strike rate (20 percent), ERA, FIP (2.55), and xFIP (3.05), per FanGraphs.
Monegro, who hails from the Dominican Republic, originally signed with the Red Sox for just $35,000 as an international free agent in February 2020. Because of the COVID-19 pandemic that ensued, the Santo Domingo native was unable to make his pro debut until the following July. He then compiled a 3.63 ERA in 13 Dominican Summer League starts (39 2/3 innings) that year and followed by struggling to a 7.36 ERA over 25 2/3 innings in the 2022 Florida Complex League.
Given the struggles he endured in his stateside debut, the success Monegro enjoyed this past season may have been surprising to some. Internally, however, the Red Sox had high hopes for Monegro going into 2023 because of what he accomplished in the offseason. Assistant general manager Eddie Romero acknowledged as much in a July email exchange with BloggingtheRedSox.com.
“We were really excited about Monegro heading into the spring,” Romero wrote. “He impressed a lot with the physical shape he came into spring training, and has continued to work since then — this has been key to his early-season success. He’s super athletic with a lightning quick arm which contributes to his ability to have a plus breaking ball. He’s tightened up his delivery to let his athleticism show and be consistent with his mechanics.”
Standing at 6-foot-4 and 180 pounds, Monegro operates with a diverse arsenal that consists of a four-seam fastball that averages just under 95 mph, a 12-to-6 curveball that sits between 76-81 mph, and an 88-90 mph cutter, per his Baseball America scouting report. That same scouting report notes that Monegro “also has a two-seamer and splitter, though the latter is a work in progress. In order to stick as a starter, he’ll likely need to either sharpen one of his pitches into a plus offering or develop the splitter into a solid offering.”
Monegro — who does not turn 22 until October — is now regarded by Baseball America as the No. 18 prospect in Boston’s farm system, which ranks fourth among pitchers in the organization behind only fellow righties Wikelman Gonzalez, Luis Perales, and Richard Fitts. He is expected to return to Greenville for the start of the 2024 season, though he could reach the upper levels by the end of the year since he can become Rule 5-eligible for the first time next winter.
