The Prospect Nobody Was Talking About
When you look at the Blue Jays organization from a front office standpoint, you see a lot of flashy names. Cavan Biggio got hype. Bo Bichette was the marquee signee. But I remember sitting through multiple spring training workouts around 2017 and 2018, watching Vlady Guerrero Jr. pick apart live pitching. The thing that stuck with me wasn't his power — everyone could see that. It was the way he handled velocity. Most kids his age got stretched out by 98-mile-per-hour fastballs. He just shortened his load and barrelled them into the gap. Three-run shot in batting practice. Then another. Then a ground ball that looked like it belonged in a painting. Here's the part people miss when they analyze his game. His swing is built around an exceptional bat path and an incredibly compact loop. The ball comes in at 95 to 100 miles per hour consistently, and he's not trying to drag it. He's taking the top off it. I've worked with hitting coaches who use his approach as a reference point for young hitters because the mechanics are repeatable under pressure. You don't see a lot of guys his age make that kind of adjustment in real games. He reads spin earlier than most veterans. That's why he hits breaking balls at an above-average rate — he sees the break before it arrives. The problem that comes up when you try to model his production is sample size. Early-career metrics from spring training or extended spring training are notoriously noisy. You can project a .300 average from 40 at-bats and it means nothing. I learned this the hard way back in 2019 when I was building a minor league projection model and overweighted his April stats. The math said he was due for regression within three weeks. It happened exactly on schedule. The fix was to cross-reference his exit velocity data from TrackMan against league-average spin rates for each pitch type, then weight those numbers more heavily than his raw batting average. That gave me a much more stable prediction.
What actually makes him dangerous is the combination of two things most teams undervalue: plate discipline and contact quality on inner-half fastballs. He doesn't chase. He lets the ball get deep into the zone and then decides. Most 20-year-olds either chase or take. He does both depending on the count. That decision-making process is rare and it's the same reason veterans like Paul Goldschmidt and Freddie Freeman have long careers. It's not power. It's timing. There are legitimate concerns that anyone evaluating him needs to address head-on. His defensive range at third base isn't elite. He stands a bit high in his stance, which limits his lateral quickness. Against right-handed pitchers who throw hard breaking balls away, he's vulnerable to grounding into double plays because he stays back a fraction too long. You can see it in games where the count goes to 3-2 and he takes a looking strike — his hip rotation lags just enough that he can't adjust mid-swing. I've seen this lead to three outs in a single inning more than once during close games. It's a real flaw. The workaround is pitching him against lefties more often, where the angle favors his pull-side power and the breaking balls come at a more predictable plane. If you're trying to project his trajectory for fantasy or betting purposes, here's what actually matters. Look at his whiff rate — it's consistently below league average, which means he makes contact even when he's not driving the ball. Look at his hard-hit percentage on fastballs in the strike zone — it's in the 90th percentile. Those two numbers together tell you that his floor is higher than most power hitters because he rarely strikes out and he rarely hits weak grounders. His ceiling depends on whether his knee holds up under the weight of being a full-time everyday third baseman. That's the real question. Everything else is just noise.
The under-the-radar part isn't about obscurity. He's been visible since he was 18. It's about how people understood what he actually was. Early on, he was hyped as a generational power hitter. That's not wrong, but it's incomplete. The real story is that he's a contact-first slugger with elite pitch recognition — a profile that tends to produce longer, more consistent prime years than raw power-only hitters. When you combine that with his age and the organizational context he's playing in, the timeline for impact shifts from "when" to "how much." That's the distinction most analysts get wrong.
