Okamoto's start gives us a baseline of his raw skills
Still big error bars on things but certain characteristics are hard-coded and visible
He can handle third base (that is good to see) but he is not rangy or impressively athletic (meaty legs) so I am thinking the ceiling there is like, a 0 OAA 3B over an entire season. He seems to have good hands, actions, decisions so even if he is a -5 or worse, perhaps it is the variety that doesn't demoralize the team or really stand out in a bad way.
The K and BB rates are starting to approach stability, according to the typical baseball research. Since he changed leagues perhaps we need to extend that timeline but I will offer this:
Seiya Suzuki NPB in 2020, 2021: 14.2% and 16.5% K rates
Seiya Suzuki MLB career: 24.9% K rate
That's an 8.4-10.7% jump
Yoshida NPB: 5.7% and 8.1%
Yoshida MLB: 12.9%
4.8 to 7.2% jump (but even bigger in a relative sense, i.e. more than twice as many strikeouts as the one year)
Okamoto's last three NPB years were 11.3%, 15.9%, and 18.8%. So his baseline in NPB was more variable than the others. But he is also 30, compared to Suzuki who was 27 and not declining yet when he came over. So if you think that Okamoto's projected NPB K rate in 2026 and onward would have been 16% or higher, then an MLB K rate in the upper 20s completely tracks. The 32.4% rate so far does seem a bit too high, though.
The closest qualified players to him in 2026 WHIFF RATE are:
Benintendi (36.4, 17.9), Happ (30.0, 26.5), James Wood (31.2, 31.0), Manzardo (34.1, 26.6), Teoscar (29.7, 29.0), Gorman (28.7, 33.7), Corbin Carroll (25.7, 21.3)
The numbers in parenthesis are their 2026 and career K rates
I don't know how instructive that list is. There are some positives and negatives. Swing rate is also an important toggle when it comes to K%. New comp strategy...
Swing rate 43.8%, SwStr% 14.3% = these or Kaz's 2026 rates. He has been quite passive.
Here are the players since 2017, min 2000 PA, who Swing 45% of the time or less and whiff at least 10% of the time. I like this list because Soler and Suarez were comps in my head.
