LHP Brian Matusz will make at least one more rehab start on Friday at Class A Frederick after coughing up six runs on seven hits in an inning with Double-A Bowie on Monday. "Didn't go too well for him," Orioles manager Buck Showalter said. Matusz was 1-4 with a 2.94 ERA and 56 strikeouts over 49 innings in 58 games last season with Baltimore.

LHP Brian Matusz (back) did not have any setbacks in his rehab assignments at Double-A Bowie, allowing one run with three strikeouts in two innings. Matusz was eligible to come off the DL on April 10, but manager Buck Showalter wants him to throw in at least one more minor league game before activating him.

LHP Brian Matusz is on the disabled list (left intercostal strain) but Buck Showalter said he should be ready to come off on April 10. Matusz struggled with the injury through much of spring training but the Orioles need some left-handed help in the bullpen.

LHP Brian Matusz (left intercostal strain) went on the 15-day disabled list retroactive to March 25. He might be able to return by the end of April.

Matusz had successful surgery on his right shoulder, Roch Kubatko of MASNsports.com reports.

Considering the surgery was performed on his non-throwing shoulder, he's likely to be fully healed in a month or two --- well before spring training starts up in 2016. He should be counted on to pitch in more late-inning situations next year provided his shoulder is fully up to speed.

Matusz will undergo right shoulder surgery Monday, Brittany Ghiroli of MLB.com reports.

As a result of the injury, Matusz season will likely come to a close. He's posted a 2.98 ERA and 1.18 WHIP while collecting 56 strikeouts over 48.1 innings in 56 appearances this season, and should continue to serve in late-inning relief again in 2016.

Matusz was charged with a blown save in Tuesday's 6-5, extra-inning victory over the Red Sox after surrendering a solo homer in 0.2 innings.

Matusz promptly served up a 418-foot dinger to the first batter he faced, Travis Shaw. The eighth-inning blast knotted the score at 5-5 and was the third earned run given up by Matusz in his last three trips to the mound. Tonight's debacle also represented the veteran reliever's second consecutive blown save in as many opportunities. Despite the recent struggles, Matusz has provided quality work overall out of the bullpen, and his current 2.87 ERA and 1.15 WHIP are significant improvements over his career numbers in those categories.

Matusz retired the only two batters he faced on five pitches to preserve Baltimore's eighth inning lead and earn a hold in Monday's win over the Red Sox.

Matusz stranded two runners from the normally steady-handed Darren O'Day. With Matusz now serving normally as a left-handed specialist, it is surprising that this is just Matusz's second hold on the season. He rebounded from being charged two runs for the only two batters he faced Saturday against the Royals.

Matusz struck out the only batter he faced in Monday's win over the Braves.

After being tied to trade talks and being suspended for a foreign substance, Matusz has been nothing but stellar since returning from the suspension June 14. Since then, Matusz has allowed one earned run in 12.2 innings with 21 strikeouts. He remains an important part of Baltimore's bullpen, but there is no chance he will turn into a closer right now. The Orioles continue to look for a bat on the trade market and the lack of prospects could mean the Orioles would consider parting with Matusz in the right deal.
