Tommy John, Japan, and the future

Are pitchers’ severe elbow sprains rarer in Japan than in MLB? If so, what is the principle issue, how might context lead to different outcomes on different sides of the Pacific, and what do these say about the future of these injuries in Japan, especially for those pitchers here who throw really hard?

Could it be that Japan is doing something right that MLB might learn from? These questions were posed recently by my podcast partner, John E. Gibson (@JBWPodcast).

One of the advantages of being independent of MLB is that Japan does things differently for different reasons. Thirty years ago, Japan was different in that complete games were still expected from every regular starting pitcher, and it was not uncommon to see a really good pitcher in a high run context throw 140 to 150 pitches three times over a 15-day span until his career was essentially over at the age of 30.

Japan is no longer an outlier in that department, but it is an outlier with a fairly fossilized six days between starts, with the starting pitcher showing up to practice the following day to make sure everything is intact, and then taking the next day off.

Travis Sawchik recently published a superb article in The Score, titled, “Velo vs. Injury: Is there a better way for pitchers?

Sawchick found minimum velocities in MLB are rising faster than maximum velocities, suggesting more maximum-effort pitches. He also stated that 37 percent of the pitchers on active MLB rosters have had Tommy John surgery.

I actually do have the material on hand in the form of html files needed to learn whether a similar phenomenon is happening in Japan, but need to write some code to capture it, so I’ll pass on that for a moment and simply make some obvious points.

  1. Severe elbow sprains that call for surgery are indeed rarer in Japan. I checked every active pitcher the first week of this season to see if he had a published record of surgery to repair an elbow ligament sprain.
  2. Dr. James Andrews, who has just retired from a career that included repairing elbow sprains, said recently that the current epidemic in America is not limited to professional pitchers, and that most of the surgeries performed, either Tommy John or his cousin “the brace,” are on high school and college pitchers.
  3. Dr. Kozo Furushima, who has performed a huge number of Tommy John surgeries in Japan, said surgeries on Japanese college pitchers are also increasing rapidly.

Japan’s TJ frequency

I went through the active pitchers for the first week of this season, and counted 143 pitchers who were whose pro careers essentially started in Japan – this includes SoftBank’s Livan Moinelo, since his pro experience in Cuba was extremely limited before playing in NPB and his teammate, Carter Stewart Jr., who turned pro here.

NPB news: April 14, 2024

Happy Roki Day to all who celebrate. In Japan on Sunday, we had a long-awaited moment for Japan’s other BIG name youngster, while a couple of series sweeps were wrapped up.

Sunday’s games

Tigers 2, Dragons 1: At Nagoya Dome, Hanshin earned a series tie, one win, one loss and one tie, by snapping Chunichi’s seven-game unbeaten streak.

Chunichi’s Kodai Umetsu struck out 13 while allowing two two runs on four hits and three walks over eight innings, but Hanshin came from a run down behind seven scoreless innings from Hiroto Saiki with Takumu Nakano singling and scoring the tying run in the third and then singling in the go-ahead run in the seventh.

Giants 2, Carp 1: At Tokyo Ugly Dome, Yomiuri’s Rei Takahashi went x innings, and allowed his first CL run, while Thomas Hatch allowed two runs over six innings in his second Japan start, with rookie Masaya Hagio, the Giants’ second draft pick in 2022, hitting a two-run homer, his second, to bring Yomiuri from a run down in the third as the the hosts swept the three-game series.

Swallows 9, BayStars 0: At Yokohama Dome, Munetaka Murakami, a day after being dropped down to the No. 2 spot for the first time as a pro and going 2-for-3 with a walk and his first RBI, batted second again and hit his first home run of the season, a first-inning solo shot. Miguel Yajure threw six innings for the Swallows.

The BayStars suffered from a case of “timely Chunichitas” a malady that describes teams setting the table but unable to bring themselves to take the final step toward scoring. DeNA got the leadoff hitter on in the first three innings, and twice having two on with one out against Yajure. Trailing 2-0 in the seventh, DeNA wheeled out Yuito Mori for his CL debut after the Hawks cut the injury-plagued former PL saves leader, and the Swallows blew him out of the water in a seven-run inning.

Yakult’s Domingo Santana and Jose Osuna each went 3-for-4 with Osuna doubling twice.

Marines 9, Eagles 2: At Miyagi Stadium, Roki Sasaki touched 159 kph on one pitch, and had one more at 158 and another at 157 in a 106-pitch outing in which he allowed a first-inning solo homer to Hideto Asamura, three walks and two singles and another unearned run over seven innings while striking out seven. Sasaki improves to 2-0 with a 1.86 ERA.

The Eagles, who allowed an NPB-high 29 doubles through Saturday, have now allowed 33.

Hawks 4, Lions 1: At the domed stadium formerly known as “Prince,” SoftBank baptized Kona Takahashi‘s belated season debut with some fire to complete a three-game sweep. Yuki Yanagita went 3-for-4 with a double and an RBI. Taisei Makihara singled and scored in the third, and tripled in two and scored in the Hawks’ three-run sixth.

Jesus Aguilar scored Seibu’s only run off Ryosuke Otsu (2-0) with his second homer in two games, in the seventh.

Buffaloes 6, Fighters 3: At Osaka UFO Dome, Orix’s Luis Castillo allowed Ariel Martinez‘s three-run first-inning homer but had little trouble after that over six innings he struck out eight and walked one. RBI singles in the bottom of the first from Tomoya Mori and Marwin Gonzalez tied it, while Ryo Ota doubled in the go-ahead run in the third and singled and drove in one of Orix’s two-run fifth.
