Toronto Blue Jays All-Star catcher Alejandro Kirk underwent surgery on his fractured left thumb and is projected to be sidelined for six weeks. The injury occurred during a foul tip in a recent game against the Chicago White Sox. Following the injury, Kirk was placed on the 10-day injured list and consulted a hand specialist, who recommended surgery that involved placing a screw in his thumb. Kirk, who had a successful previous season with a batting average of .282 and 15 home runs, will be replaced by Tyler Heineman and rookie Brandon Valenzuela. The Blue Jays have struggled at the start of the 2026 season, holding a record of 4-6. They are also facing additional injury challenges, including veteran right-hander Max Scherzer, who left his last start due to forearm tendinitis but is expected to pitch again soon. Right-hander Cody Ponce will undergo surgery on his right knee and is expected to miss about six months. Additionally, infielder Addison Barger has been placed on the injured list with a left ankle sprain.
