Tampa Bay Rays outfielder Kevin Kiermaier (knee) exited Saturday night's matchup against the Orioles. The 31-year-old began to experience right knee soreness and was replaced by Brett Phillips out in center. Kiermaier is batting .233 this season, with 56 hits, 32 runs, 23 RBI, and seven stolen bags. While he is considered day-to-day, a potential absence wouldn't be a massive blow for managers in most formats.
