In the rare instances when he gets a day off from defense, the Padres usually slot him in as the designated hitter.However, on Wednesday night, Stammen elected to start Tatis Jr. at second base, a position he’s familiar with but has played just 25 times and made 41 appearances at across his 112 games this season.The outfield will instead consist of Luis Rengifo in left field, Jackson Merrill in center and Jase Bowen in right, while Jake Cronenworth will serve as the designated hitter.Padres 8/5F.
