The SoftBank Hawks reached Japan’s season finale having won their last five regular-season games and their first three postseason games. They also started Game 1 at Yokohama Stadium with a 12-game Japan Series win streak dating back to 2018’s Game 3 against Hiroshima.
Former Texas Ranger Kohei Arihara, backed by the Hawks’ impressive defense, proved to be the difference in Saturday’s 5-3 Game 1 victory. Arihara drove in his first two runs as a pro to open the scoring against Andre Jackson, and SoftBank tacked on three more in the ninth before DeNA held Roberto Osuna’s feet to the fire in a three-run ninth.
This is part 2 of my lists of the most effective pitches thrown in Japan in the 2024 regular season. “Best” is subjective, but these pitches were the most effective in terms of their influence on game situations, by leading to better or worse counts or having worse results when put in play.
In Part 1, I explained the way the evaluations were created, and included the top 10 pitches overall, the top fastballs, and the top sliders.
Part 2 starts with Japan’s favorite secondary pitch, the splitter. For the most part, I have stuck with the SpoNavi website’s name for each type of pitch, except when Delta Graphs, which is more rigorous, is obviously talking about the same pitch as something else. The changeup of Hiroshima’s Allen Kuri is listed as a splitter by DG and so I’ll list that here.

Now to the cutters, where the No. 1 pitcher, rookie Teruki Yoshino, just scraped over the minimum, but it perhaps explains why he started Game 5 of the CL playoffs’ final stage…

Delta Graphs categorizes Allen Kuri’s shoot as a two-seamer, but the shoot was much less effective than the two-seamer (+.006 as opposed to -.032).
