Wiki says: Tanaka is a 188 cm (6 ft 2 in), 93 kg (205 lb) right-handed power pitcher with a high three-quarters delivery. He throws a four-seam fastball that usually sits around 145 to 149 km/h (90 to 93 mph) (clocked as fast as 96 mph at Dodger Stadium in 2009 WBC) and complements it with a vicious 82-86 mph slider with a sharp, late break. He also throws a solid 84-88 mph splitter, and a two-seam fastball. In 2007, Tanaka often relied on this slider to strike out batters. He has since worked on improving his other offspeed pitches to induce more groundballs and get batters out more efficiently. One area of Tanaka's pitching that is often cited as needing improvement is his motion from the stretch. He allowed a league-high 28 baserunners to steal on him in 2007...but as always with the Japanese buyer beware...look at this from high school (in a single tournament) "Tanaka threw 742 pitches in 52⅔ innings (six appearances) in the tournament, striking out 54 and walking 20 with a 2.22 ERA." Lots of mileage on these arms. They say Darvish is an exception in that his father was Iranian and fought the Japanese arm overuse culture.
