Still, it appears the Orioles are at least discussing the possibility of pushing Matusz back a day or two to err on the safe side. Matusz was diagnosed with a nose contusion, which is essentially a bruise, after a bunt attempt came back and hit him in the indoor cages during pitchers' batting practice for the team's upcoming Interleague schedule. X-rays taken on Tuesday evening were negative, and the Orioles will see if the area swells up overnight.
"For me, I am mentally prepared to pitch tomorrow, and I'm ready to go," Matusz said. "But with the nose being something that could swell up, who knows? So I'm going to play it how it goes and see how it feels tomorrow."
The Orioles have an internal option in struggling starter Jake Arrieta -- who was moved to the bullpen after Friday's outing -- who could pitch Wednesday on regular rest, if needed. Showalter also didn't rule out the possibility of the club making a move to get someone from Triple-A if need be.
The Orioles were originally holding off on making a corresponding roster move for second baseman Brian Roberts until they got word on Matusz, but that didn't end up being the case. Instead, Steve Tolleson was optioned to Triple-A Norfolk, with Nolan Reimold (herniated disk) moving to the 60-day disabled list to clear a 40-man spot.
Reimold is flying to Baltimore to get another MRI -- to compare to one taken earlier. Reimold is pain-free, but is still dealing with numbness and tingling in certain areas on his left side, and his strength isn't coming back nearly as fast as the team had hoped. Reimold has not been cleared to participate in any baseball activities at this point.
