The Reality of Masahiro Tanaka’s Fastball
Six months ago, we were all idiots. We were all idiots because we figured the Yankees were idiots for letting Masahiro Tanaka pitch. It felt like elbow surgery was inevitable, UCL tears being things you don’t just play through, so it felt strange to see the Yankees in denial. Oh, we all thought we knew what was better. Turns out the Yankees might’ve been on to something. Turns out those doctors have more than just pieces of paper. Tommy John might still be an inevitability. Greg Holland pitched through something like this for a year. The elbow still got him. The elbow might still get Tanaka, but tonight he’s starting a playoff game. Tonight, he’s the guy, at least until Andrew Miller and Dellin Betances are the guys. It’s safe to say now it worked out.
Remain in the flashback, though. Go back six months to when Tanaka made his first start. There was so much attention on his fastball — on its usage, and on its velocity. Observers thought the fastball would be a dead giveaway. They thought the injury would make the fastball worse, and they thought Tanaka wouldn’t be able to cut it without a decent fastball. Just about everyone, after all, builds off the fastball. It’s the pitch at the center of the pitch-type solar system.
In the end, Tanaka’s fastball actually gained velocity this season. He started 24 times, with a mid-3s ERA, and his average fastball was up the better part of one mile per hour. In a sense, the fastball wasn’t a giveaway. But if you stare long enough, you see two things. One: overall, Tanaka was pretty good. Two: Tanaka’s fastball was pretty bad.
