In a Toronto Blue Jays season that has over-indexed on unpleasant surprises, Brandon Valenzuela has been one of the few players who have exceeded expectations.
The rookie catcher built some buzz during spring training, but he was the clear third catcher at the beginning of the season and began at triple-A. When Alejandro Kirk’s thumb fracture prompted a surprisingly early MLB debut on April 5, Valenzuela was a career .201/.294/.315 hitter at triple-A. The projection system ZiPS predicted that if he saw MLB action in 2026, he’d give the Blue Jays a similar .207/.274/.338 line.
While Valenzuela hasn’t been a world beater, his .222/.300/.429 slash line is good for an above-average 105 wRC+, and his 0.7 fWAR ranks third among Blue Jays position players. Along with those offensive numbers has come some strong defensive work, even if there have been hiccups, like his run-scoring throw into left field on Monday.
Valenzuela’s performance — along with the profound offensive struggles of Tyler Heineman, whose wRC+ currently sits at 0 — has many Blue Jays fans wondering if he’s ready to take over as the team’s backup catcher when Kirk returns. Not only that, but his multi-faceted contribution to the Blue Jays has raised questions about whether his ceiling might be higher than it seemed when the team first acquired him in a low-profile trade for Will Wagner at last year’s trade deadline.
It is too early to make definitive declarations on that, but Valenzuela’s first 25 games in the big leagues offer some clues about the type of player he might become, both offensively and defensively.
Valenzuela's bat
While Valenzuela’s first 70 trips to the plate have been productive, a rookie’s first impression offensively isn’t always representative of what they offer in the long term.
Blue Jays history has many notable examples of players who looked good offensively in small samples as rookies, only to perform significantly worse in the years to come. Here are a few examples:
Even the player Valenzuela was traded for, Wager, might end up fitting this description. The infielder hit .305/.337/.451 in 86 plate appearances as a rookie for the Blue Jays in 2024, slashed .225/.324/.279 between Toronto and San Diego the next year, and hasn’t been seen in the majors in 2026.
At this point, Valenzuela’s MLB results do not tell us much about what he can be offensively, even though he’s come by them honestly and has expected numbers that closely match his production with a .243 xBA and .418 xSLG. There is a reason the ZiPS projection system, which saw him struggling so much at the plate in 2026, has him hitting just .208/.277/.347 from here on out. Perhaps it’s too slow to react to his numbers with the Blue Jays, but the basic idea is that the body of work is too small for it to change things much.
While the results are a faint positive sign, some of the underlying numbers for Valenzuela are intriguing. That starts with his raw power. The hardest-hit ball he’s managed this season (111.4 mph) is well above average.
Only 95 of the 386 hitters with 25-plus batted balls this season have managed something harder, and only 10 of those players are catchers.
That power ceiling is held up by above-average bat speed, particularly from the right side, where his average swing (72.5 mph) is almost a full mph faster than the MLB average (71.7 mph). Those characteristics also pair well with a tendency to keep the ball in the air, as he’s run a groundball rate below 40 per cent in four straight minor-league seasons before 2026, and that number sits at 38.1 per cent early in his major-league career.
If given sufficient at-bats, Valenzuela is likely to put a few balls over the fence; the big question for him is whether he can make enough contact. His strikeout rate so far (28.6 per cent) is high, and not likely to drop too much considering he maintained a rate between 23 and 25 per cent in each of his last four minor-league seasons — and MLB pitching is significantly harder to make contact with.
His whiff rate (30.2 per cent) is also well above MLB average (25 per cent), largely due to a heavy chase rate that’s also well above the league standard (34.2 per cent vs. 28.5 per cent). It’s possible this is something that changes with time, but it’s worth remembering that Valenzuela is in his age-25 season and the fundamentals of his hitting style are less likely to shift than they would be for a 21-year-old breaking through for the first time.
On a micro level, it’s intriguing that Valenzuela has collected all of his extra-base hits against secondary pitches while slugging just .207 against fastballs and .188 vs. four-seamers in particular. If he can’t do anything with hard stuff, that will be a catastrophic issue, but it’s far too early in his career to assume that trend will continue. As an example, Kazuma Okamoto struggled to generate hard contact against anything slow when he was first adjusting to the MLB game, until he found his footing.
It is impressive that Valenzuela is holding his own in the majors offensively. Very few rookie catchers do that. In the last 50 seasons, 384 rookie catchers have had 50 or more plate appearances, and just 22.8 per cent managed a wRC+ of 100 or better. He’s working with some real power, and his inclination to elevate the ball should help ensure that power evolves into tangible production.
The question with him is likely to be how much consistently he can tap into that power, and how much strikeouts could drag down his overall offensive contribution.
Valenzuela’s defence
While Valenzuela has caught just 175 innings in the major leagues, the results so far have been excellent across the board per Statcast metrics, despite a relatively high error total (3).
His 5 Fielding Run Value currently ranks eighth among all MLB position players despite his limited playing time. While it’s difficult to gauge how much of that is small-sample-size noise, it’s notable that he came to the Blue Jays with a sterling defensive reputation. For example, MLB Pipeline described him as an “impressive receiver” who “manages a pitching staff well” and considered a 15 home run power ceiling more than enough if his defence remained “such a strength”.
It’s impossible to be certain of a catcher’s true talent in framing or blocking at the highest level based on so few MLB games, but, notably, what we’re seeing from Valenzuela in those areas is in line with the skill set he demonstrated over 3,414 minor-league innings before reaching Toronto.
The framing, in particular, has jumped off the page as just one catcher in the majors (Patrick Bailey) can top his +3 framing runs. For a little extra context on how big a difference maker he’s been in this area, here are Valenzuela’s called-strike numbers against an average framing catcher — in this case, Nick Fortes, of the Tampa Bay Rays.
While that’s impressive, the sample is too small to be confident that Valenzuela will keep it up. An area where his prowess is easier to be confident in is controlling the running game. Even after struggling a bit with the Rays this week, the 25-year-old has thrown out 31.8 per cent of base runners, well above the MLB average (23.7 per cent). The underlying numbers are also excellent.
Valenzuela’s pop time of 1.89 ranks 10th among 62 catchers who’ve tried to catch at least five runners at second base, thanks to a throwing velocity of 84.9 mph that ranks ninth. The time it takes him to uncork his throws after he catches pitches (0.62 seconds) isn’t as outstanding, but still well above average, ranking 19th in that group. Those numbers don’t say anything about his accuracy, but his strong career minor-league caught stealing rate (32 per cent) and some of the plays he’s made with the Blue Jays suggest that he can put the ball where it needs to go.
In his brief time with the Blue Jays, Valenzuela has provided stellar defence, despite a couple of noteworthy blunders. His glove was his calling card when he was acquired, and his brief MLB career has only provided confirmatory evidence that good things happen when he straps on the tools of ignorance.
Just 25 games into his career, it’s too early to render a verdict on what Valenzuela will be in the majors. It is enough to determine that he has tools that stand out among his peers, even at the game’s highest level. Not only that, but his standout skills — raw power and defensive skill behind the plate — are some of the most valuable an MLB player can have. That doesn’t mean he’s on his way to dethrone Alejandro Kirk someday, or become an elite trade asset like Gabriel Moreno, but the Blue Jays have every reason to be encouraged by what they’ve seen so far.
