The Orioles announced a series of roster moves Wednesday, designating infielder Vimael Machin for assignment and transferring right-hander Brandon Young to the 60-day injured list (thereby ending his season). Their 40-man roster spots will go to infielder Emmanuel Rivera and right-hander Roansy Contreras — the latter of whom was already known to be on his way to the majors. Their contracts have been formally selected from Triple-A Norfolk. Baltimore also optioned right-hander Yaramil Hiraldo to Norfolk.
Machin, 31, played his first four big league games since 2022 earlier this month after the O’s summoned him from Norfolk. He went just 1-for-12 but made the most of that lone knock, depositing it over the right field wall for the second home run of his brief MLB career. He’s now played in parts of four seasons — the other three all coming with the A’s — and posted a .204/.286/.264 batting line in 373 trips to the plate.
Though he’s never fared well in the big leagues, Machin is a lifetime .289/.371/.449 hitter in just under 1400 plate appearances at the Triple-A level. He’s a lefty hitter with a good eye at the plate, experience at all four infield positions and a pair of minor league options remaining, so it’s at least feasible that another club plucks him off waivers as a depth option. If not, he’ll have the right to reject an outright assignment from the Orioles upon clearing waivers, should he prefer to explore other opportunities.
Young, 27, made his big league debut with the O’s earlier this season. He’s made a dozen starts despite rocky results — a testament to the depleted status of the Baltimore rotation this year. An undrafted free agent in the shortened (five-round) 2020 draft, Young has pitched 57 2/3 innings in 2025. He’s been tagged for an ugly 6.24 ERA despite passable rate stats (18.4% strikeout rate, 8.6% walk rate). The long ball has been his primary undoing, as he’s served up 12 homers in his relatively small sample of work (1.87 HR/9).
A hamstring strain sent Young to the 15-day IL last week. At the time, interim manager Tony Mansolino acknowledged that the right-hander would miss more than the minimum, but it wasn’t clear until today’s move to the 60-day IL that Young’s season is formally over; there simply aren’t enough days left on the calendar for him to fulfill that 60-day minimum.
Young can be controlled for six more seasons and has two minor league option years remaining beyond the current campaign. He’ll likely stick around as a depth option for a rotation that figures to be a focal point of the Orioles’ forthcoming offseason dealings.
Rivera, 29, came to the O’s late last season and went on a tear in 27 games down the stretch. He played well enough to be tendered a contract and sign for $1MM in spite of lack of track record. HIs 2025 season hasn’t gone as hoped. In the same number of games as last year, Rivera has slashed .229/.299/.271. The O’s passed him through waivers earlier in the summer, and he’s hit fairly well in Norfolk, slashing .297/.362/.356 in 246 turns at the plate.
Contreras, 25, is a former top prospect who looked like a potential long-term piece in the Pirates’ rotation following a strong 2022 big league debut. He’s struggled in every subsequent campaign, however, logging a 5.47 ERA over his past 136 2/3 big league frames. He landed with the Orioles via waivers late in the offseason, and Baltimore was able to pass him through waivers themselves, removing him from the 40-man roster. He’s now been added back after tossing 91 2/3 innings of 3.73 ERA ball for the Tides. Mansolino indicated yesterday that Contreras would either start today’s game or pitch several innings of bulk relief.
