Big news day in Baltimore, so here’s the rundown after Buck Showalter’s press conference.

The Orioles purchased the contract of reliever Miguel Socolovich and activated catcher Taylor Teagarden from the 60-day disabled list – both 40-man roster moves.

To make room, they designated lefty Dana Eveland for assignment and outrighted catcher Ronny Paulino to Triple-A Norfolk.

Paulino, who already cleared waivers, can refuse the assignment and become a free agent. He has 72 hours to make that decision and said Saturday that he hasn’t decided what he will do.

Eveland is on waivers now and the team will know by Monday if he clears. He also can refuse an assignment to Norfolk, but he’s on a major league deal and would forfeit his salary if he chose to be a free agent. So if he clears, he’ll go to Norfolk and likely pitch out of the rotation – especially if the Orioles have to promote another Tides’ starter to the big leagues.

Jason Hammel had his MRI on his right knee at 1 p.m. Results aren’t known yet, but Showalter said there was no swelling today. The hope is that he can avoid a DL stint; if he can’t, the likely call-up would be Brian Matusz, who pitched well in his last start. Matusz is slated to pitch Sunday for Norfolk. Jake Arrieta also could be an option, but the Orioles would prefer to let him have some more time with minor league instruction. They’d like to do the same with Matusz, too, but may not have a choice.

Chris Tillman was scheduled to start Sunday against the Detroit Tigers, but was dealing with some back spasms and will be pushed back to Monday. Miguel Gonzalez, who was supposed to pitch Monday against the Minnesota Twins, will now start Sunday. Showalter said he wanted to get Gonzalez back on the mound (Tillman pitched Monday for Bowie) as quickly as possible after a long layoff and Tillman’s back spasms allowed the club to do that.

The Orioles have an opening in the rotation for Tuesday, and Zach Britton lines up as the most likely candidate for that one – especially with Eveland being designated.

Socolovich can be used in a variety of roles in the bullpen, including multiple innings.

Teagarden likely will make his first start of the year Sunday against reigning AL MVP Justin Verlander.
