Wolfram allowed one hit and no walks in a scoreless eighth inning for a hold Monday against the Mets. He struck out one.

5d agoRotowire

Wolfram continues to operate as a left-handed specialist out of the Baltimore bullpen. He gave up multiple runs in three consecutive outings to begin the month of August, but Wolfram has since yielded just two runs in his last 12 appearances. He has a 4.66 ERA, 1.28 WHIP and 56:14 K:BB with 13 holds over 48.1 innings (56 outings).

Wolfram tossed a perfect ninth inning to earn the save in Sunday's 5-2 win over the Astros. He did not record a strikeout.

Jul 19Rotowire

With Tyler Wells and Andrew Kittredge unavailable, Wolfram was called upon in the ninth inning and recorded his first career save on just 12 pitches. On the year, the 29-year-old Wolfram owns a 4.55 ERA, 1.31 WHIP and 32:8 K:BB to go along with 11 holds and one save across 29.2 innings.

Wolfram picked up a hold Friday against the Nationals, striking out two in a clean eighth inning.

Jun 27Rotowire

The 29-year-old left-hander has now turned in 23 outings with no earned runs allowed among 29 appearances this season, though he has given up multiple earned runs on three occasions. Wolfram has managed to be a fairly reliable setup man in 2026 despite having a .281 batting average against him, posting a 3.47 ERA, 1.29 WHIP and 27:3 K:BB with nine holds across 23.1 innings.

The Orioles reinstated Wolfram (back) from the 15-day injured list and appointed him as their 27th man for Sunday's doubleheader versus the Tigers.

May 24Rotowire

Wolfram will rejoin Baltimore after spending the minimum amount of time on the shelf while recovering from a back strain. The Orioles will have to option a player to the minors following the twin bill, and despite being designated as the 27th man, Wolfram could stick around with the big club. Though he maintains a 4.85 ERA and 1.54 WHIP through 13 innings on the season, Wolfram's 30.6 K-BB% and 1.72 SIERA indicate that he's been one of Baltimore's more dominant bullpen arms.

The Orioles placed Wolfram on the 15-day injured list Tuesday, retroactive to Saturday, with a lower-back strain.

May 12Rotowire

Wolfram hasn't pitched since he gave up one run in two-thirds of an inning against the Marlins last Wednesday, and it appears his absence has been due to a back injury. His move to the injured list will rule him out until at least May 24, and the O's will recall Tyler Wells from Triple-A Norfolk to fill the vacancy in their bullpen.
