Vladimir Guerrero Jr. launched a 108-mph, 419-foot solo homer and stole second base in Toronto’s 12-7 loss to the New York Mets on July 12, 2026. The blast—his only hit of the game—came off a fastball in the ninth inning, but his back issues persist as the Blue Jays eye a mental reset before the stretch run.

What happened in the game? Guerrero drove the ball to center field, where it landed at 419 feet, his longest of the season. He also had two hard-hit balls that didn’t drop, though both earlier hits turned into double plays. Toronto’s offense struggled, with Guerrero going hitless on Tuesday and slashing just **.268/.348/.349** through 81 games.

Why is Guerrero’s back tightness a concern? The 27-year-old has battled lower back tightness for weeks, missing Tuesday’s game entirely. Manager **John Schneider** said Guerrero “experienced some tightness while swinging” before Tuesday’s contest and opted for caution. “There’s always a time when a guy needs a little break,” Schneider told reporters, adding the Blue Jays “need Vlad” for a deep run.

How does this affect fantasy managers? Guerrero remains a daily fantasy play outside shallow leagues, where rosters can absorb depth. His four homers this season trail last year’s 38, but his track record suggests a second-half rebound. Rookie **Sean Keys**—hitting **.284/.409/.619** with 21 homers in the minors—will cover first base while Guerrero rests.

What’s next for Toronto’s lineup? Keys, 23, made his MLB debut at first base against the Rangers earlier this week, batting sixth while Guerrero sat at DH. The Blue Jays are testing depth as they chase a playoff spot. Schneider expects Guerrero back for Wednesday’s series finale against the Mets, though Keys’ production will determine his long-term role.
