The Orioles have designated infielder Emmanuel Rivera for assignment and reinstated Jordan Westburg from the 10-day injured list, per a team announcement. Baltimore also optioned lefty Grant Wolfram to Triple-A Norfolk, clearing a spot for the activation of lefty Jose Castillo, whom the O’s claimed off waivers yesterday.
Rivera, 29, came to the Orioles following a DFA in Miami last summer. He erupted for a .313/.370/.578 slash and four homers in 73 plate appearances down the stretch, prompting the O’s to tender him a $1MM contract in the offseason. He hasn’t replicated that output in 2025, however. Through 127 turns at the plate, Rivera has logged a tepid .250/.291/.283 slash that more closely resembles his career .245/.305/.360 output in 1169 plate appearances.
He’s still a quality defender at third base and has added some experience at first base, but Rivera is out of minor league options and thus couldn’t simply be sent to the minors without first being removed from the 40-man roster by way of a DFA. He’ll now be made available to the game’s 29 other teams via outright waivers. If and when he clears, Rivera would have the right to reject a minor league assignment in favor of free agency (both by virtue of having more than three years of MLB service and a prior outright in his career).
It’s been a stop-and-start year for the 26-year-old Westburg. He’s been highly productive when healthy enough to take the field but has endured lengthy IL stints owing to both a hamstring strain and a right ankle sprain. He’s just now returning from the latter of those two maladies after spending nearly a month on the shelf.
When he’s been able to take the field, Westburg has popped 25 extra-base hits (15 homers, nine doubles, one triple) and recorded a stout .276/.326/.473 batting line while splitting his time between third base and second base. Dating back to last season, Westburg has belted 33 home runs in just 751 plate appearances — despite being a right-handed hitter in a ballpark that overwhelmingly sapped right-handed power in 2024 (before altering their left field dimensions this past offseason).
More to come.
