Akinori Ōtsuka

is a Japanese former baseball pitcher who coaches for the Chunichi Dragons in Nippon Professional Baseball. He was the setup man for the San Diego Padres and the Texas Rangers. He was also the closer for Japan's 2006 World Baseball Classic–winning team.

Otsuka threw a low-90's 4-seam fastball (tops out at about 94 mph) that is very straight, along with a hard, late-breaking slider. He employed an unorthodox pitching delivery wherein he lifted his lead leg up very slowly, tapped his glove, then fired to home plate, making his pitches look faster coming out of his hand and thus harder to pick up.

San Diego Padres Otsuka came to the United States after several years of pitching in the Japanese League when his former team, the Chunichi Dragons, used the posting system to solicit bids from MLB clubs for the right to negotiate with him. The Padres made the winning bid and signed him to a three-year contract on December 9.

Otsuka made his major league debut April 6, 2004 against the Los Angeles Dodgers, earning the loss after giving up a walk-off single to Robin Ventura. He struck out Paul Lo Duca for his first major league strikeout.

Sullivan reported that, in an interview in Japan, Otsuka said "If there is the team which needs me as a closer, I am going to think about (the trade)". Due to Gagné starting the season on the DL, Otsuka began the 2007 season as the closer. With the trade of Gagne to the Boston Red Sox, Otsuka assumed the closer's role again. However, Otsuka went on the DL after experiencing tightness in his throwing shoulder. His stand-in was C. J. Wilson.
