Care to back that up with anything? EVERYTHING I've seen said exactly what I wrote, splitter = bad for elbow.

Somebody wearing a uniform undoubtedly uttered the words "I told you so" on Wednesday night after news of Tanaka's elbow issue spread across the majors, and it's very possible that this was a four-word refrain in a lot of clubhouses. That four-word refrain would only be repeated on Thursday night when the league learned that Tanaka had a partial UCL tear in his elbow, an injury that often leads to Tommy John surgery. That's because over the first two months of this season, even as Tanaka dominated hitters and earned the respect of opponents, there was a feeling among many players on other teams that it was only a matter of time before he broke down.
That opinion was not based on his daunting accumulation of pitches in Japan, where he threw 160 pitches in a start last fall before pitching in relief the next day. Rather, opposing hitters and pitchers and coaches and managers watched him throw splitter after splitter after splitter at high velocity, and they reached the conclusion that he was destined for surgery.
For now, the Yankees are saying that Tanaka has a chance to rehab the injury. But if surgery is needed, there will be a lot of nods around the game, because the perception of the splitter is that it's an elbow-killer, and Tanaka relied so heavily on the pitch in his first days in the big leagues. In fact, according to Fangraphs, 25 percent of the pitches thrown by Tanaka this season have been splitters, easily the highest in the majors.
Percentage of splitters thrown
1. Tanaka 25.0 percent
2. Hiroki Kuroda 22.9
3. Dan Haren 16.0
4. Tim Hudson 14.2
5. Ubaldo Jimenez 13.7
Among the pitchers who employ the splitter as a major weapon, Tanaka also has thrown it at the highest velocity, 86 mph.
The day after Tanaka beat the Red Sox on April 22, David Ortiz mentioned around the batting cage that he had never seen a pitcher throw that many splitters; Jonny Gomes, standing nearby, nodded. And every time teams saw Tanaka, this became part of what they took away. He's incredibly talented, many opponents would say privately, and competitive, and has a great feel for the baseball. And wow, he throws a lot of splitters.
