BALTIMORE -- The Orioles have decided to flip starters Miguel Gonzalez and Chris Tillman, with Gonzalez pitching Sunday's series finale to give Tillman, who had a back spasm on Thursday, an extra day.
"He can probably pitch the [original] day," manager Buck Showalter said of Tillman, who threw for Double-A Bowie on Monday. "But it also keeps the ball in Gonzalez's hand instead of waiting another day, just to be on the safe side."
Gonzalez last pitched Friday, July 6, making his first Major League start in memorable fashion. The 28-year-old tossed seven dominant innings against the Angels to earn a spot in the rotation and will now face Tigers ace Justin Verlander.
Tillman also fared well in his season debut, holding the Mariners to two unearned runs on two hits over 8 1/3 innings. He also struck out seven and is expected to be recalled from the Minors for Monday's start in Minnesota.
