Dominic Canzone is slugging through Seattle's lost season with 22 HR and a 131 wRC+

What happened

Dominic Canzone is having a strong season at the plate for a Seattle Mariners club that, as of Saturday night, had scored the fewest runs in Major League Baseball. The outfielder/DH has slugged 22 home runs while posting a .258/.327/.482 slash line and a 131 wRC+ across 474 plate appearances, per FanGraphs' David Laurila. In a lineup that has otherwise struggled to generate offense, Canzone and Randy Arozarena are the only two players with qualifying plate appearances and a wRC+ clearing 108.

The performance is not a bolt from the sky — at least not to fans in the Pacific Northwest. Canzone spent the prior season establishing himself in Seattle, logging a .300 batting average, 11 home runs, and a 141 wRC+ in 268 plate appearances. The sample was modest, but the direction was clear.

Why it matters

The Mariners are 70-80 and sitting third in the AL West, 5 games back, with a Wild Card ranking of 9th and 6.0 games relative to the cut line. The offense has been historically poor — the fewest runs in MLB is not a distinction any front office frames and hangs on the wall — and the club is reportedly facing a significant offseason overhaul. Against that backdrop, Canzone's production stands as one of the few unambiguous bright spots in Dan Wilson's lineup.

Selected by the Arizona Diamondbacks in the eighth round of the 2019 draft and subsequently moved to Seattle in 2023, Canzone has developed into what Laurila describes as a formidable presence in the batter's box. The question worth asking is how he got here, and Canzone, speaking directly to Laurila, had a clear answer.

Is this a mechanical story or a mental one?

Both, per Canzone — and he draws a sharp line between the two.

On the approach side, Canzone told Laurila that the hardest thing to acquire as a major-league hitter is understanding how pitchers will attack you in specific situations, and then building a plan around that knowledge. "Everybody has the ability," he said, "so it's all about looking for the right thing in the right spot." He contrasted that with his college days at Ohio State, where the calculus was simpler: hunt the fastball, because opposing pitchers couldn't reliably land multiple off-speed pitches for strikes. At that level, he said, you could lay off breaking stuff and the sharpness simply wasn't there to punish you for it.

The major leagues, as Canzone has learned, do not extend that courtesy.

He still hunts fastballs, but the meaningful difference now is that he is hyper-aware of the percentages inside scouting reports. He cited tendencies with runners in scoring position as a specific example, noting that he will sometimes sit on off-speed pitches in select situations. He described a scenario to Laurila in which a pitcher with a heavy spin rate and a bases-loaded count is unlikely to simply throw something hittable down the middle — so sitting off-speed in that spot becomes the logical play. The key word, he emphasized, is situational — not a blanket adjustment, but a targeted one.

On the mechanical side, Canzone told Laurila he has developed what he calls a higher finish in his swing. He described his natural stroke as very flat, which creates a tendency to roll over the ball. Because his dominant hand sits on the bottom of the bat, he said he has to make sure his top hand stays through the ball and works higher rather than releasing early. The adjustment is subtle in description and, given the slash line, apparently meaningful in practice.

The numbers

The season line Laurila presents — .258/.327/.482, 22 home runs, 131 wRC+ in 474 plate appearances — tells a consistent story. A wRC+ of 131 means Canzone has been 31 percent better than a league-average hitter when park and environment are accounted for. His prior-season line of .300 batting average and 141 wRC+ in 268 plate appearances was the foundation; the current season is the expansion.

The Mariners' broader offensive context sharpens the picture considerably. A team that entered Saturday having scored the fewest runs in baseball is not a team that obscures individual production — it isolates it. Canzone and Arozarena are the only regulars clearing a 108 wRC+. Everyone else in the lineup, by that measure, has been at or below a modest threshold, which makes the two of them less a supporting cast and more a two-man show in a very quiet theater.

Where the club stands

Seattle is 70-80 (.467), third in the AL West, 5 games back of the division lead, and sitting ninth in Wild Card positioning at 6.0 games relative to the cut line. The club enters Monday on a one-game losing streak. The schedule sends them to Angel Stadium for three games against the Los Angeles Angels: Kade Anderson opposes Reid Detmers on Monday, Logan Gilbert faces Ryan Johnson on Tuesday, and George Kirby draws Yusei Kikuchi on Wednesday.

That Angels series arrives a few days after the Mariners reinstated Víctor Robles from the family medical emergency list, returning him to the active roster. The roster picture has been in motion throughout the stretch run, as it tends to be in September when the expanded 28-man limit gives clubs additional flexibility to shuffle pieces in and out.

What we don't know yet

Laurila's piece captures Canzone's explanation of his development but does not include any club characterization of his role going forward, any contract details, or any projection of his place on the roster beyond this season. The offseason overhaul that Seattle is reportedly facing — given the historically poor offense and near-certain playoff miss — leaves a great deal unresolved about which pieces return and in what capacity.

Canzone's own comments, as reported by Laurila, are descriptive rather than forward-looking. He explains what changed mechanically and mentally; he does not forecast what comes next. That is, perhaps, the appropriate posture for a player on a 70-80 club with a lot of offseason noise ahead.

What to watch

The most immediate question is whether Canzone's production holds through the final weeks of a season that has otherwise been difficult to watch in Seattle. The Angels series this week offers a concrete near-term sample against a division opponent, and the results will land in whatever file the front office is assembling ahead of what is reportedly a substantial roster rethink.

Beyond the immediate schedule, the swing adjustment Canzone described to Laurila — the higher finish, the top hand staying through the ball — is the kind of mechanical detail that tends to get stress-tested late in a season when pitchers have a full year of data on a hitter. How he fares in those final plate appearances, against pitchers who have had time to study his tendencies, is the next chapter of a development arc that has been quietly building since he arrived in the Pacific Northwest. The 474 plate appearances already on the ledger are no longer a small-sample caveat. They are the argument.
