Kazuma Okamoto Has Given the Blue Jays a Breath of Fresh Air
In a Blue Jays lineup that's been underperforming this season, Kazuma Okamoto has been a much-needed bright spot offensively.

The Toronto Blue Jays have gotten a lack of offense in the power department from their franchise cornerstone in Vladimir Guerrero Jr. (two home runs in 142 at-bats) and they’ve sorely missed out on the home run-hitting ability from George Springer, among other names. Overall, the Jays have been carried by their pitching staff, and that’s not saying too much.
Toronto’s pitching staff has undergone many injuries already this season and some poor performances from its healthy arms, but their offseason signing of Dylan Cease has loomed as the best pickup they made on the pitching side coming into this season. One could argue that it was the best deal period, but there’s one name that deserves that notion instead.
Kazuma Okamoto has absolutely mashed in his first season in MLB after signing a four-year, $60 million deal with the Blue Jays this past offseason, and it couldn’t be coming at a better time. Okamoto has timed his success at the plate perfectly with the power slumps of virtually every other hitter in the lineup. He’s essentially the main reason they’ve been competitive offensively over the last few weeks.
NPB Superstar
When Okamoto signed with the Blue Jays, he was departing a career in Japan’s NPB that saw him escalate to the level of one of the best hitters they’ve seen in recent history. He had tallied seven consecutive seasons with at least 25 home runs and 80+ RBI and was coming fresh off a 2025 season where he slashed .327/.416/.598 and hit 15 home runs in 69 games for the Yomiuri Giants.
One of the most alluring parts of his skillset was his ability to control the strike zone and limit strikeouts. In 2025, Okamoto had an identical amount of walks and strikeouts (33, 11.3%) and he had notched a walk rate of at least 9.8% in every one of his eight seasons in NPB.
Fresh off a World Series appearance in 2025, this was one of the first signings that depicted the attraction that Toronto had gained as a free agent destination. While the Jays hadn’t been able to close a deal with another Japanese phenom a few offseasons ago in Shohei Ohtani, bringing one of NPB’s brightest stars in Okamoto was a key addition they made to improve their lineup.
Toronto snatched up the primetime free agent as their marquee offensive acquisition of the offseason and he’s more than delivered on expectations. As opposed to last year’s free agent signing of Anthony Santander, Okamoto has surpassed him in virtually every way.
Slugging With the Best
Simply put, Okamoto has put himself among the best hitters in baseball in 2026 due to his performance at the plate. So far this season, he is slashing .248/.333/.482 with 10 home runs, 25 RBI, and an 11.3% walk rate.
Entering Sunday, May 10, Okamoto leads all third basemen in home runs and RBI while ranking fifth among them in wRC+ (128). Using FanGraphs’ ‘plus’ stats to grade Okamoto’s numbers in comparison to league averages, his isolated power (ISO+) is 57% above average, showing the impact of his power tool at the plate this season. He’s also tied for the most barrels at his position with 16.
Okamoto sits in the top 15% of hitters in expected slugging rate (.531), average exit velocity (93 MPH), barrel rate (16.7%), and hard-hit rate (53.1%). He’s done most of his damage on four-seam fastballs, posting a .327 average and .655 slugging percentage on them this season with a +9 Run Value. Another one of the reasons he’s been so effective is his bat speed, which comes in at 73.7 MPH on average, the second-highest on the Blue Jays.
Okamoto had a series for the ages when the Jays played the Twins in Minnesota last week, as he went 5-for-16 with four home runs and seven RBI, including the first two-homer game of his MLB career. This made him one of three primary third basemen this season with a streak of 3+ consecutive games with a home run and is one of just four players to hit four home runs over a three-game span.
Gold Glove Candidate?
Okamoto is most highly touted for his abilities at the plate, but it’s certainly worth noting his skills on the defensive side of the baseball. At the hot corner, he’s made many run-saving and extra-base hit-saving plays over his first month and a half at the MLB level. Although some fielding metrics don’t shed too much light on his successes with the glove, he’s been very stable at the hot corner this season.
Overall, Okamoto has a 0 Fielding Run Value and a 1 OAA so far in 2026, but these surface level numbers don’t tell the whole story. They’ll show more of a complete story with a larger sample size, but it’s important to look at the individual plays he’s made.
On batted balls that require him to move towards the plate (running ‘in’), Okamoto has a +4 OAA and is one of just two third basemen to achieve such a mark this season. The only other is Maikel Garcia (2025 Gold Glove winner) of the Kansas City Royals, who is currently in the 97th percentile in Outs Above Average.
One of the main concerns with Okamoto’s skillset when he initially signed with the Jays was his defense at third base. There were speculations among the Toronto faithful that he might have to be relinquished to first base if his fielding was too poor. Even though he’s graded out around league average defensively thus far (or ever so slightly below it), the fact that Okamoto is playing solid defense that doesn’t make you wince or cringe when the ball’s hit towards him is a reward in and of itself.
Closing Thoughts
Kazuma Okamoto might just give Munetaka Murakami of the White Sox some competition as one of the best signings from this past offseason, as he’s leading the Blue Jays in a number of offensive categories. He’s been one of the only consistent pieces in Toronto’s lineup that is producing at the plate with regularity, so there’s plenty to be excited about in his game.
The only real concern with Okamoto’s game is his swing-and-miss issues, as he’s struck out nearly 30% of the time this season after only posting a single season mark of 20% or higher in his career in NPB. The adjustment period to MLB is still omnipresent when watching Okamoto play, and one can’t expect him to make all the changes necessary to MLB competition in just over a month of time.
Look for Okamoto to really come into his own as the season progresses and establish himself as one of the Jays’ best hitters in all areas. With time and continued success, he’s going to be a dangerous presence in this lineup for quite a while.
