Gonzales will move up a day to start for the Mariners on Tuesday in Philadelphia, Ryan Divish of The Seattle Times reports.
The Mariners have decided to flip-flop Gonzales and Logan Gilbert, who will now go Wednesday. Gonzales -- who will be pitching on an extra day of rest Tuesday -- is coming off his strongest start so far this season, having struck out nine while limiting the Brewers to two runs over six innings Wednesday.
