Rengifo, who entered Thursday on a 14-game hitting streak, had been warming up in the on-deck circle when he sustained the injury.

After one of his swings, he stepped forward a few steps and then hunched over. He walked toward the dugout steps and hunched over again before athletic trainer Mike Frostad and manager Phil Nevin rushed to him. Eduardo Escobar, who had been near the steps anticipating his own at-bat, also walked over to Rengifo.

Rengifo then walked back down the steps to the dugout. Randal Grichuk took over his spot in the lineup.

Rengifo isn’t the only ailing Angels player. Aside from Shohei Ohtani (right oblique inflammation) missing a fourth consecutive game, Mickey Moniak, who was in the starting lineup, was scratched three minutes before the first pitch because of back tightness. Brett Phillips replaced him in center field.
