Shaw exited Tuesday's game against the Cardinals as a precaution, as he has recently fouled a lot of pitches off his foot, Adam McCalvy of MLB.com reports.

EDGE Analysis

He was 0-for-2 with two strikeouts prior to being lifted for Hernan Perez. It sounds like he is just day-to-day with a sore foot. Shaw's production has trailed off this month, hitting .237/.315/.400 with three home runs in 80 August at-bats entering play Tuesday.
