Toronto Blue Jays first baseman Vladimir Guerrero Jr. won't play in the World Baseball Classic due to a knee injury, per Rob Longley of the Toronto Sun.
The two-time All-Star left Friday's spring training game against the Tampa Bay Rays with discomfort in his right knee.
Manager John Schneider told reporters after the game they were checking out Guerrero's knee to see how it is: "We're playing it safe at this point."
Guerrero previously committed to play for the Dominican Republic in the WBC, which begins on March 8.
The Dominican squad with Guerrero was arguably the favorite to win the tournament.
