Showalter made a slight adjustment to the pitching rotation. Right-hander Jake Arrieta, who was given an extra day of rest because of Thursday's day off, is scheduled to pitch the series opener against the White Sox in Chicago on Monday night, depending on the health of the bullpen. That would push back Chen to Tuesday. … Adam Jones' fourth-inning single broke an 0-for-18 slump with runners in scoring position for the Nos. 2-5 hitters in the Orioles' lineup. ... Left-hander Dontrelle Willis, who left Triple-A Norfolk's game Wednesday after nine pitches, was placed on the seven-day disabled list Thursday with a left forearm strain. In other minor league moves, infielder Zelous Wheeler was reassigned from Norfolk to Double-A Bowie, right-handers Miguel Gonzalez and Kyler Newby were added to the Tides' roster from extended spring training and the Baysox released outfielder Edgardo Baez on Friday to make room for Wheeler.
