Orioles Select Houston Roth, Recall Elvin Rodríguez

After trading Seranthony Domínguez to the Blue Jays this afternoon, the Orioles have made some additional transactions to shake up their bullpen ahead of game two of a doubleheader against Toronto. They have recalled right-hander Elvin Rodríguez and selected the contract of fellow right-hander Houston Roth, both from Double-A Chesapeake. The Domínguez trade freed up one roster slot, and to open another spot on the active roster, Baltimore optioned Yaramil Hiraldo to Double-A.

While Rodríguez and Roth are coming up from the Double-A (and Hiraldo is headed down to the Chesapeake Baysox), it’s worth noting that all three pitchers have spent the majority of the season at Triple-A Norfolk. However, Chesapeake is significantly closer to Baltimore than Norfolk. So, the O’s were presumably stashing Rodríguez and Roth at Double-A in case they were needed as depth. With that in mind, Danielle Allentuck of The Baltimore Banner suggests these are likely “temporary moves” to quickly replace Domínguez and replenish the bullpen after game one of the doubleheader.

Rodríguez, 27, signed a split major league deal with the Brewers over the offseason after a strong showing in Japan in 2024. However, he gave up 18 runs in 18 2/3 innings with Milwaukee, leading the team to designate him for assignment earlier this month. Baltimore scooped him up off waivers, and if he gets in a game, he will be making his Orioles debut. Before his time overseas, the right-hander pitched for the Tigers in 2022 and the Rays in ’23. All in all, he has a career 9.23 ERA in 51 2/3 MLB innings. The O’s will hope he can look more like the pitcher who put up a 1.80 ERA over 45 innings in NPB last season.

Roth, also 27, has spent his entire professional career with the O’s, rising through their minor league ranks since the 2019 campaign. If he gets in a game, he will be making his major league debut. In 24 appearances (36 2/3 innings) between Double-A and Triple-A this year, the right-hander has a 2.21 ERA but a 4.02 FIP and 4.55 xFIP. He has posted impressive strikeout rates at High-A and Double-A over the past two seasons but struggled to miss bats upon his promotion to Triple-A earlier this year. His double-digit walk rate only exacerbates that problem.

Hiraldo, 29, was recalled earlier today for his fourth stint with the Orioles this season. He pitched two innings in game one of the doubleheader, giving up one run on a solo home run by Joey Loperfido. All told, he has pitched 4.1 MLB innings in 2025 with two strikeouts, no walks, and three hits allowed. He has a 4.19 ERA in 38 2/3 minor league innings this year, but his 32.9% strikeout rate and 5.78 strikeout-to-walk ratio are more promising. Those numbers are all the more impressive considering he spent the 2022-24 seasons in the Atlantic and Mexican Leagues. Prior to 2025, he had not pitched in affiliated ball since the Diamondbacks released him in 2021.
