Vladimir Guerrero Jr. exited Toronto's 5-2 loss to Pittsburgh in the fifth inning with hamstring tightness after two acrobatic defensive plays, including a splits-at-first that saved a potential run and a long, decision-making pickup by Bo Bichette to end the third. Guerrero returned to the field in the fourth but was pulled in the top of the fifth as a precaution, with an MRI scheduled for clarity. John Schneider called it a grind-season tightness and expressed hope Guerrero can be back in the next day or two. The situation leaves Toronto monitoring lineup plans closely while Pirates showcased clean defense and a two-way edge with Triolo's impact. Fantasy players should watch Guerrero's MRI results and any early-week lineup shifts as Toronto decides how to balance risk and performance moving forward.
