Buck Showalter does not expect to make any more roster cuts until after Sunday's games. Showalter will manage the Orioles at Ed Smith Stadium on Sunday while bench coach John Russell manages the split-squad team that plays against the Philadelphia Phillies. Pitching coach Rick Adair will also will be with the split-squad team so he can watch Jason Hammel pitch. …Steve Johnson will start the game in Sarasota. … Right fielder Nick Markakis (neck) has two to three more days using Dosepak medication before meeting with doctors again. … Right-hander Miguel Gonzalez pitched in a Double-A game at Twin Lakes Park on Friday, partially to avoid pitching against an American League East rival. Showalter said Gonzalez reportedly looked good and had no issues. … Right-hander Chris Tillman, who is dealing with abdomen soreness, threw a bullpen session Thursday and felt no discomfort. He will throw two innings in minor league camp at Twin Lakes on Saturday. Wei-Yin Chen will pitch in a minor league game there Monday, which is an Orioles off-day. … Brian Matusz will start Tuesday's game in Fort Myers against the Red Sox. … Roberts stole his first base of the spring Friday, and he did it with a head-first dive into second base — a good sign for someone who has dealt with concussion issues in the past. … Friday's attendance was 8,100, the third sellout of the spring at Ed Smith Stadium.
