Blue Jays Place Alejandro Kirk On 10-Day IL, Recall Brandon Valenzuela

The Blue Jays are placing catcher Alejandro Kirk on the 10-day injured list with a left thumb fracture, according to Mitch Bannon of The Athletic. Catching prospect Brandon Valenzuela is being recalled from Triple-A in a corresponding move, per Hazel Mae of MLB International. Keegan Matheson of MLB.com was first to report that Valenzuela is in the Blue Jays’ clubhouse this morning.

Kirk exited last night’s game against the White Sox in the tenth inning after taking an Austin Hays foul tip off his thumb. Tyler Heineman took over behind the plate, and Kirk was promptly sent for X-rays. Although the results weren’t known until this morning, some kind of IL placement was expected for Kirk. In the end, the X-rays revealed the fracture as well as a dislocation, according to Ben Nicholson-Smith of Sportsnet. Kirk will meet with a specialist on Monday to determine whether surgery is necessary. Based on similar injuries, the Jays can expect to lose Kirk for at least six to eight weeks if he undergoes surgery.

Any extended absence would be a blow to the Jays as they look to make another deep postseason run. The team is currently 4-3 and in second place in the AL East, although they’ve been outscored by their opponents 33-31. In addition, Kirk is arguably the team’s second-most valuable player behind Vladimir Guerrero Jr. After below-average offensive seasons in 2023-24, he rebounded last year to post a 116 wRC+ along with career highs in home runs (15) and runs batted in (76). The 116 wRC+ was more in line with his 110 career wRC+ and makes him well above average for a catcher. Indeed, Kirk’s 4.7 fWAR was second only to AL MVP runner-up Cal Raleigh at that position.

As good as his offense is, Kirk is also an otherworldly defender. He was worth 9 Defensive Runs Saved in 2025, which tied for third among qualified catchers behind the Giants’ Patrick Bailey and the Red Sox’ Carlos Narváez. According to Statcast, he graded out in the 100th percentile in blocks above average (21) and in the 98th percentile for framing. While his caught stealing and pop time are closer to average, those are very minor points in what is otherwise an outstanding defensive profile. Altogether, Kirk was the second most-valuable defensive catcher in the majors last year, based on Statcast’s Fielding Run Value metric.

Further updates will come after Monday’s visit with the specialist. Obviously, the club will hope that surgery is not needed and that Kirk’s absence will be kept to a minimum. In the meantime, Toronto will rely on Heineman and Valenzuela behind the plate. Heineman is purely a backup at this stage of his career, but the club may give him the lion’s share of starts in the short term. His offense last year was surprisingly strong, with Heineman posting a 120 wRC+ in 174 plate appearances. That was far off from his career norms and partly the product of good luck, as evidenced by his .342 batting average on balls in play. On the other hand, Heineman accrued 10 DRS behind the plate, and he ranked in the 80th percentile or better for blocks, caught stealing, and framing. Thus, even if his offense regresses, his defense should help him out as a temporary starting catcher.

As for Valenzuela, the 25-year-old was acquired in a trade with the Padres last July and is one of Toronto’s top 30 prospects according to MLB.com. The team added him to the 40-man roster in November. Manager John Schneider said yesterday that Valenzuela would be called up if Kirk needed to miss time. That has now come to pass, and Valenzuela will get his first taste of the big leagues.

Valenzuela participated in major-league Spring Training this year and performed admirably, batting .304/.370/.478 with a home run and three runs scored in 27 plate appearances. He first reached Triple-A in 2024 with the Padres and returned to that level following his trade to the Blue Jays. Valenzuela was slightly above average at Double-A, though his performance at Triple-A has not been quite as strong. That’s largely due to contact issues. In 105 PA with Toronto’s top affiliate last year, he struck out at a 30.5% clip and graded out 23% worse than average by wRC+. He has shown some improvement early in 2026, cutting his strikeout rate to 17.6%. Still, his offense hasn’t been his strong suit at the top level of the minors.

Rather, Valenzuela’s value comes from his work behind the plate. His MLB.com scouting report gives him well-above-average arm strength and control of the running game. He has a 33.8% caught-stealing rate since the start of 2024, including a 35.7% rate at Triple-A, and he is also noted for his ability to work with a pitching staff. His offense may keep him from being a big-league starting catcher, but his glovework gives him a decent ceiling as a backup. For now, Heineman’s stronger recent offense probably gives him the starting job. Valenzuela has three option years remaining and could easily return to Triple-A when Kirk eventually returns.
