WEST SACRAMENTO — Dodgers shortstop Mookie Betts was scratched from the team’s lineup for Wednesday’s game against the Athletics shortly before first pitch.

The reason for his removal, or the severity of any potential injury, was not immediately clear.

The setback comes at an especially disappointing time for Betts, who was just starting to rediscover his swing after missing a month earlier this year with an oblique strain.

Entering Wednesday, Betts was hitting .373 over his last 16 games with five home runs, four doubles and 11 RBIs.

During that time he had raised his season batting average from .181 to .244 and his OPS from .591 to .744.

He had also been playing standout shortstop, ranking second at the position with eight defensive runs saved.

With Betts out Wednesday, Miguel Rojas was inserted into the lineup in his place.
