Pages was removed from Saturday's game against the Mariners with left hamstring tightness, Derrick Goold of the St. Louis Post-Dispatch reports.
Pages went 3-for-3 with a two-run homer and a walk before his hamstring forced him out of the game in the seventh inning. The Cardinals haven't provided any information on the severity of his injury, though they could be waiting for imaging results before sharing those details. Ivan Herrera and Yohel Pozo would likely split playing time behind the plate if Pages has to miss additional time.
