Ogasawara throws 4 pitches - a fastball that tops out at 94.4mp/h (average speeds of around 86-91mp/h), a 62mp/h curveball,[REF] a slider and a change-up that comes out of the hand in a similar way to his straight delivery [REF].
Upon his debut, Ogasawara threw mostly only his fastball and his change-up in the strike zone not unlike team-mate Shunta Wakamatsu,[REF] however with further experience he started landing his curveball and slider in the zone taking more strikeouts in the process [REF].
