Brian Matusz

The Orioles are considering moving left-handed starter Brian Matsuz — who was sent down to Triple-A Norfolk earlier this month — to the Tides' bullpen after lefty reliever Troy Patton landed on the disabled list Tuesday with a sprained right ankle.

The front office had been considering the switch for several days, but Patton's injury made the need for a left-hander who is capable of throwing multiple innings out of the bullpen more pressing.

"It's something Brian has talked about before as something he would welcome if it would help us and also help him get back up to the big leagues," Orioles manager Buck Showalter said. "I would surprised if he can't do it, and do it well."

The 25-year old Matsuz went 5-10 with a 5.42 ERA in 16 starts with the Orioles this year, but he has had success over his career against left-handed hitters and might be better suited for shorter stints out of the bullpen.

In four major league seasons, Matsuz has held left-handed batters to a .233 batting average, and this season lefties are hitting just .174 against him. He has a career 4.48 strikeout-to-walk ratio against left-handers.

"Until we get a couple outings of him down there, it's going to be tough to tell," Showalter said. "It might be something that doesn't work out. There's only one way to find out."

With most of the Orioles' starters being right-handed, Showalter prefers to have a left-handed long relief man to mix up the opposing lineup if needed. With Patton on the disabled list, that pitcher doesn't currently exist in the Orioles' bullpen. They traded for left-hander J.C. Romero on Monday, but he is 36 and isn't seen as a viable option for long-relief.

It's not entirely clear how many relief appearances Matsuz would need in Norfolk to get adjusted to life out of the bullpen, but Showalter indicated it might take only a couple of outings.

Patton's enthusiasm curbed

With two lefty heavy lineups ahead on the Orioles' schedule, Patton thought he was going to have a big week against Boston and Detroit.

But on Sunday, the 26-year old slipped on a curb outside his hotel and rolled his right ankle, putting him in the disabled list for the first time this year.

"It's frustrating for this team and this situation we're in facing lineups with heavy left-handed hitting lineups," Patton said. "I would be used a lot in the next few days. I feel irresponsible that I put the team in this situation."

Patton had been having his best season as a professional, going 1-0 with a 2.58 ERA while striking out 48 in 52 1/3 innings and holding left-handed batters to a .204 batting average. Because he's turned it a couple times in the past, Patton said his ankle is more susceptible to injury and rolls easier than most.

Showalter said he "hopes the ankle isn't as bad as it looks," but X-rays turned up negative and Patton is expected to return from the disabled list when he's eligible Aug. 28.

"It's extremely frustrating, very, very, very frustrating," Patton said. "I haven't felt this good as I've felt on the mound in my whole career, so it's very frustrating."

More roster moves

To clear a spot for Romero on the 40-man roster, the Orioles have designated right-handed reliever Miguel Socolovich for assignment.

The Orioles have 10 days to trade, release or ask waivers on Socolovich, who had been optioned to Norfolk after Sunday's game.

Socolovich pitched to a 6.97 ERA in eight appearances with the Orioles, but he was 4-0 with two saves and a 1.90 ERA in 28 appearances with the Tides this season, holding opposing hitters to a .179 batting average.

Romero was acquired Monday from the Cleveland Indians for minor league infielder Carlos Rojas. Romero had been 1-0 with a 2.51 ERA and 13 strikeouts in 17 appearances for Norfolk, but he was given the right to opt out of his contract after not being called up to the Orioles and signed a minor league deal with the Indians.
