The Toronto Blue Jays placed Vladimir Guerrero Jr., a six-time All-Star, on the seven-day injured list on Saturday due to concussion symptoms. In his place, outfielder Daz Cameron was called up from Triple-A Buffalo. To accommodate this roster change, Lazaro Estrada, a right-hander, was designated for assignment.
Additionally, the Blue Jays recalled left-hander Ricky Tiedemann from Buffalo and sent right-hander Chase Lee down to Triple-A on the same day. Guerrero sustained his injury during Friday’s game against the Yankees when he collided with New York rookie shortstop George Lombard Jr. during a play at third base in the sixth inning.
Following the collision, Guerrero’s helmet came off, but he managed to score a run before being replaced by Charles McAdoo at first base in the seventh inning. Manager John Schneider noted that Guerrero experienced a headache after the game and still had one the next day.
Guerrero currently holds a batting average of .263 with seven home runs and 46 RBIs. Tiedemann, who joined the team, has a record of 0-1 with a 6.43 ERA in seven games, including two starts, across various minor league levels this season.
