According to the PitchFX data at Brooks Baseball, Rangers right-hander Yu Darvish has thrown eight different pitches in his MLB career. He added a ninth on Friday night. Darvish broke out a super slow 63 mph eephus pitch to strike out Adam Lind:
Darvish is known to throw a very slow curveball, but the slow curve has averaged 69.6 mph according to PitchFX. That pitch was only 63 mph.
Maybe it was an extra slow slow curve. It's sure looked like an eephus pitch to me though.
