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. They brought up outfielder Daz Cameron from Triple-A Buffalo to take his place. In a corresponding move, Lazaro Estrada, a right-hander, was designated for assignment to make space on the 40-man roster.
On the same day, the Blue Jays also recalled left-hander Ricky Tiedemann from Buffalo and sent right-hander Chase Lee down to Triple-A. Guerrero exited Friday’s 3-1 win against the Yankees after colliding with New York rookie shortstop George Lombard Jr. in a tumultuous play at third base during the sixth inning. Lombard attempted to jump over Guerrero as he slid into third base, resulting in his knee and thigh striking Guerrero’s head, causing his helmet to come off. Guerrero managed to run home to score the tying run but appeared disoriented after crossing the plate, leading to Charles McAdoo replacing him at first base in the seventh inning.
Following the game, manager John Schneider mentioned that Guerrero experienced a headache, which persisted into Saturday. Guerrero has a batting average of .263 with seven home runs and 46 RBIs this season. Tiedemann, who had a record of 0-1 with a 6.43 ERA in seven games, including two starts, across three minor league levels this year, was also part of the recent roster changes.
