Young fireballer Masahiro Tanaka and submariner Shunsuke Watanabe faced off on April 14 in a great pitcher's duel. Tanaka got the best of Watanabe, but Shunsuke held Rakuten at bay despite allowing 12 baserunners in seven innings of work. And they couldn't have been more different in their approaches. Tanaka was routinely in the mid-90's with his fastball, and only threw three pitches below 80mph, while the submarining Watanabe didn't touch 80 the whole game. Have a look at the velocity charts to see the difference between the two.
