Vladimir Guerrero Jr. exited with hamstring tightness in the fifth after two superb defensive plays at first and a prior long catch. An MRI was scheduled to clarify the extent, with Toronto hopeful for a quick return given the timing of late-season grind. Guerrero returned for the field in the fourth before being pulled for precaution. Bo Bichette keyed the defense and the middle of the Jays’ order remains potent when Guerrero is healthy, but the injury creates a short-term vacancy that could shift daily fantasy values for Toronto. The Pirates capitalized late with Jared Triolo, and the next 24-48 hours should reveal Guerrero’s timeline and any immediate lineup tweaks.
