Triple-A Norfolk right-hander Tyler Wilson will likely head to the disabled list after he was scratched from his scheduled start Sunday with right oblique soreness.
"With the seven-day DL there, I imagine he's heading to the DL there," Showalter said.
With right-hander Mike Wright already on the disabled list with a Grade 2 left calf strain, two of the organization's top spot-start pitching options are injured. Both have also been used in a relief role at the major league level during this season to provide bullpen depth.
Wright threw off flat ground from 75 feet on Monday, an early step in his recovery, but he's still several weeks from returning.
"You can always take a starter and make him a reliever," Showalter said. "I can't take [Triple-A reliever] Oliver [Drake] and make him a starter. That's a little bit of a challenge right now with those two guys hurt."
But Showalter is confident the organization has enough bullpen depth.
"Oliver Drake is having as good a statistical year as anybody in the minor leagues. … Steve Johnson is healthy and pitching well. [Jorge] Rondon presented himself well up here, [Cesar] Cabral is having a good year down there. Our depth is in pretty good shape, maybe not from a starting point but Mike will be back shortly and hopefully Tyler won't be too long. We're in pretty good shape."
Orioles deal for RHP Buschmann
The Orioles acquired right-hander Matt Buschmann from the Cincinnati Reds on Monday in exchange for cash, according to an industry source. He will report to Triple-A Norfolk.
Buschmann, a 31-year-old who has played parts of 10 seasons in the minor leagues, Buschmann was 2-5 with a 4.25 ERA in 9 starts with the Reds' Triple-A team in Louisville. He was 6-5 with a 3.89 ERA in 13 starts with the Rays Triple-A club in Durham before exercising an opt-out with Tampa Bay this year.
Around the horn
Infielder-outfielder Steve Pearce began baseball activities Monday at the team's spring training facility in Sarasota, Fla., taking his first swings and doing some light throwing. They were the first steps in his progression from a left oblique strain. The Orioles hope Pearce can return by Sept. 1. … Right-hander Ubaldo Jimenez will fly back to Baltimore following his after work day Tuesday to have an extra day to get acclimated to the time difference before starting Friday at home against Oakland.
