Sal Frelick exited the second game of Saturday's split doubleheader against the Royals in the fourth inning with left side tightness. The Brewers right fielder grimaced during his second at-bat where he lined a single to center. After a lengthy discussion with manager Pat Murphy and trainer Brad Epstein, Frelick left the contest, raising immediate concerns about his availability.

Brandon Lockridge replaced Frelick as a pinch runner and eventually took over in left field, shifting Blake Perkins to right field. Frelick had contributed earlier in the day, singling and walking during Milwaukee's 5-2 victory in the first game of the doubleheader. The injury could potentially disrupt the Brewers' lineup for their upcoming series.

The 25-year-old is in his fourth season with Milwaukee, which selected him with the 15th overall pick in the 2021 amateur draft. Frelick has become an important piece in the Brewers' outfield, making his sudden exit a significant development. The team will likely provide an update on his condition after further medical evaluation.
