Toronto Blue Jays manager Charlie Montoyo doesn't think a cracked fingernail that forced Aaron Sanchez to exit Sunday's game against the Oakland Athletics early will cause him to miss Saturday's scheduled start, also against the A's.

Sanchez, 26, was forced out of his latest start after 4.0 innings and 59 pitches with a cracked nail on his right middle finger. The Jays went on to win the game 5-4, completing a series sweep.

The nail is on the same hand on which Sanchez had off-season surgery after an accident with luggage in July.

Through five starts this season, Sanchez is 2-1 with an earned run average of 2.77 and a WHIP of 1.346. He has struck out 23 and walked 16 in 26.0 innings pitched.

The Jays (11-12) open up a two-game set against Kevin Pillar and the visiting San Francisco Giants (9-14) at the Rogers Centre on Tuesday night, but will be without the services of infielder Freddy Galvis in the starting lineup.

The club says Galvis has tightness in his left hamstring that also caused him to leave Sunday's game early.

Through 20 games this season, the 29-year-old Galvis is batting .315 with five home runs, 12 runs batted in and an OPS of .865.
