Japanese RH pitcher, Tomokazu Ohka, 40, is trying to make it back to the Major leagues as a knuckleballer, via link. Ohka was in Arizona back in November 2 of this year, and he threw 60 plus pitches in front of scouts from a number of MLB teams (Orioles, Royals, Rays, and Diamondbacks). Ohka has been working on improving his knuckleball pitch ever since he was released by the Yokohama Baystars in year 2011.
Tomokazu Ohka played for 10 years there at the Major league level (with the Red Sox, Expos/Nationals, Brewers, Blue Jays, and Indians respectively), he currently owns a record of 51-68 with an earned run average of 4.26 in 202 games played (1070 innings pitched overall) in his big league career.
Tomokazu Ohka, also, is just the only second active player left remaining in Baseball to have played with the Montreal Expos… with Bartolo Colon (now with the Atlanta Braves) as the other former Expos player.
