Zunino is expected to sit for Thursday's series finale against Baltimore, Bob Dutton of the Tacoma News Tribune reports.

Analysis:

Zunino is set to catch and bat eighth Wednesday against lefty Wei-Yin Chen, but figures to see at least a slight dip in playing time after the M's acquired Welington Castillo from the Cubs on Tuesday. General manager Jack Zduriencik suggested Zunino is still the starter, because while he's struggled offensively, he's continued to play strong defense, though it's possible the two right-handed swingers could move into a more even timeshare if Zunino fails to pick it up at the plate.
