BOSTON -- On Friday night, Orioles second baseman Jonathan Schoop felt discomfort in his right side after a swinging strikeout to end the top of the seventh inning, and felt it again when fielding a grounder in the field in the bottom half of the frame, after which he was removed for precautionary reasons.
On Saturday, Schoop was headed for an MRI in the morning, and before the afternoon could even kick into gear the club had announced that the second baseman was being placed on the 10-day disabled list with a right oblique strain.
"There's Grades 1 through 5, with 5 being the most severe and [Schoop's injury] was a 1," said Showalter, explaining Schoop's MRI results following Saturday's 10-3 loss to Boston. "I just talked to Jon, he's really down. We're looking at it [glass] half full, I'm not going to have everyone start painting a negative picture there. We have some opportunities for some other guys.
"The reason we brought in people like Pedro [Alvarez] and Danny [Valencia] and [Engelb] Vielma. ... We have some people that are capable of holding the fort down until he gets back. We're thinking a little bit better scenario than what could have been. We think we caught it kind of early."
Vielma made his Major League debut as Schoop's defensive replacement on Friday night and Timothy Beckham moved over from third base to second for Saturday's game. Valencia got the start at third base. 
"Whatever the team needs" said Beckham, who played 77 games in his career at second base prior to Saturday. "Put a lineup out to win some ballgames, I'm down for it. It's not an unfamiliar position, so let's do it and if I need to play second, I'll play second."
The Orioles activated starter Alex Cobb ahead of his start Saturday, so no other corresponding roster move was necessary. 
"We've got some other options," said Showalter. "We knew we were going to have to make room for Alex today. I wish it wasn't for Jon, but it looks like that's where we're headed. That time of year."
Ynoa's shoulder structurally sound 
Right-hander Gabriel Ynoa, who has been on the disabled list since March 26 with a stress reaction from shin splints, had an MRI on Friday on his right shoulder which revealed inflammation, but no structural damage.
"Ynoa's MRI came back, just rotator [cuff] inflammation. Structually he's fine," Showalter said. "I think the plan is to give him an injection shortly, probably Monday, just to see if they can speed up the process."
Ynoa did received an injection for the shin splints that landed him on the disabled list, and is progressing well with that injury.
"It's almost healed," Showalter said of the shin issue. "That was as good a news as you can get with him."
