How has ex-Red Sox pitching prospect Elmer Rodriguez fared since being traded to Yankees?

In light of Carlos Narvaez’s late-game heroics against his former team at Fenway Park on Friday night, it feels like an appropriate time to check in on how the prospect the Red Sox dealt to the Yankees for their breakout catcher in what looked like a minor trade six months ago is faring in his new organization so far.

Funnily enough, that prospect, Elmer Rodriguez, worked out of the bullpen for the first time this season against High-A Greenville on Friday night. In five scoreless innings of relief for Hudson Valley (New York’s High-A affiliate), the 21-year-old right-hander scattered just two hits and two walks while striking out eight of the 18 batters he faced. He threw 76 pitches (44 strikes), generating 12 swings-and-misses as the Renegades blanked the Drive, 1-0.

Through his first 11 outings (10 starts) for Hudson Valley, Rodriguez has forged a 2.70 ERA and 2.47 FIP with 74 strikeouts to 25 walks over a staff-leading 60 innings of work in which opponents have batted just .172 against him. That includes a .205 batting average against right-handed hitters and a .133 batting average against left-handed hitters.

Among 20 qualified South Atlantic League hitters coming into play on Saturday, Rodriguez ranked second in batting average against, FIP, and groundball rate (52.9 percent), third in xFIP (3.10), fourth in strikeouts per nine innings (11.10), strikeout rate (30.3 percent), ERA, and WHIP (1.03), and fifth in swinging-strike rate (14.6 percent), per FanGraphs.

A Puerto Rican native, Rodriguez was originally selected by the Red Sox in the fourth round (105th overall) of the 2021 draft out of Leadership Christian Academy in Guaynabo. He received an under-slot $497,500 signing bonus and slowly worked his way up Boston’s organizational ladder before ending the 2024 season in Greenville. Along with $250,000 in international bonus pool space, he was traded to New York for Narvaez on the final day of the Winter Meetings in December.

Rodriguez entered the 2025 campaign regarded by Baseball America as the Yankees’ No. 16 overall prospect, but has since moved up to the No. 4 spot, which ranks third among pitchers in New York’s farm system behind only fellow righties Bryce Cunningham and Carlos Lagrange. As noted in his Baseball America scouting report, the 6-foot-3 hurler boasts a diverse pitch mix that includes an upper-90s fastball that reaches 98-99 mph, a gyro slider, a sweeper, a curveball, and a splitter.

Rodriguez, who turns 22 in August, could very well be in line for a promotion from Hudson Valley to Double-A Somerset shortly. That is noteworthy when considering the fact that he can become eligible for the Rule 5 Draft for the first time this winter if he is not added to New York’s 40-man roster by the November protection deadline.

Though there are still some things to iron out, such as his command and developing arsenal, a new challenge for Rodriguez in the form of a move from High-A to Double-A would surely aid Yankees decision makers in determining if he is worthy of a 40-man roster spot in the coming months.
