What happened with Vladimir Guerrero Jr.’s surgery
The procedure was performed at the Laser Eye Center of Miami by Dr. Gabriel Lazcano, according to a post from the clinic that was cited by Major League Baseball and said Guerrero was doing well after surgery.
Guerrero had worn contact lenses during games before undergoing the procedure, making improved vision one possible factor in the Blue Jays star’s effort to reset before the 2027 season.
The surgery is not being presented as a confirmed explanation for his production decline, and there is no guarantee it will change his results at the plate.
A difficult 2026 season in Toronto
Guerrero finished 2026 with a .260 batting average, a .332 on-base percentage and a .356 slugging percentage across 609 plate appearances.
He hit nine home runs and drove in 57 runs, while his 56 walks represented his lowest total in a full season since his rookie year in 2019.
The lack of power was especially notable because Guerrero had produced one of the strongest postseasons in franchise history during Toronto’s 2025 run, when he slugged .795 with eight home runs.
Toronto finished 79-83 and missed the playoffs, leaving Guerrero’s rebound among the biggest questions facing the club as it plans for 2027.
Why the Blue Jays are watching his swing
Major League Baseball’s analysis identified changes in Guerrero’s timing and swing mechanics as possible contributors to his decline, including a career-low 6.9 per cent barrel rate compared with 12.2 per cent in 2025.
His hard-hit rate also dropped from 50.7 per cent in 2025 to 44.3 per cent in 2026, while his chase rate rose to a career-high 30.6 per cent.
Those figures suggest that the central challenge was not simply making contact, but producing the kind of efficient contact that had made Guerrero one of baseball’s most dangerous hitters.
His average bat speed remained strong at 76.3 miles per hour, ranking in the 92nd percentile among qualified hitters, which gives Toronto reason to believe the problem may be correctable rather than a permanent decline.
What comes next for Guerrero and Toronto
Guerrero will now have the offseason to recover from the procedure, refine his timing and prepare for the second season of his 14-year, US$500-million contract.
The Blue Jays will likely evaluate his vision, swing decisions and power output during spring training rather than draw conclusions from the surgery alone.
For Toronto, a return to anything close to Guerrero’s previous level would materially change the outlook of a lineup that struggled to replace his missing production in 2026.
The next meaningful checkpoint will come when Guerrero begins baseball activities and eventually faces live pitching ahead of the 2027 campaign.
