The Toronto Blue Jays placed Vladimir Guerrero Jr., a six-time All-Star, on the seven-day injured list due to concussion symptoms on Saturday. In response, they brought up outfielder Daz Cameron from Triple-A Buffalo while designating right-hander Lazaro Estrada for assignment to free up space on the 40-man roster. Additionally, left-hander Ricky Tiedemann was recalled from Buffalo, and right-hander Chase Lee was sent down to Triple-A.
The move came after Guerrero exited Friday’s game against the Yankees with a head injury following a collision with New York rookie shortstop George Lombard Jr. during a chaotic play at third base in the sixth inning. Despite the collision that dislodged Guerrero’s helmet, he managed to score a run before being replaced by Charles McAdoo at first base in the seventh inning.
Following the game, manager John Schneider mentioned that Guerrero was experiencing headaches, which persisted into Saturday. Guerrero, who currently boasts a .263 batting average with seven home runs and 46 RBIs, is a key player for the team.
Meanwhile, Tiedemann had a mixed season in the minors, posting a 0-1 record with a 6.43 ERA in seven games, including two starts, across three minor league levels this year.
