Kazuhiro Sasaki - Professional Career

Professional Career

After playing college baseball for Tohoku Fukushi University, Sasaki was drafted with the seventh pick in the first round of the 1989 draft by the Yokohama Taiyō Whales (now named Yokohama DeNA BayStars) in Japan's Central League. He played for them from 1990–1999, before joining the Seattle Mariners in 2000. He joined a bullpen that had been one of the worst in the Major Leagues, and during his rookie year won the closer job from a floundering José Mesa. Sasaki's out pitch, a devastating split-fingered fastball that drops when arriving at home plate, was nicknamed "The Thang" by Mariners radio announcers. He complemented it with a four-seam fastball that could reach the low-90s. Sasaki maintained a rigorous throwing program, sometimes at odds with club management, that saw him throw up to 100 pitches following games in which he did not appear.

Sasaki's transition to American baseball began with his being named American League Rookie of the Year. For three years, along with Jeff Nelson and Arthur Rhodes, Sasaki was an integral member of the back of Seattle's bullpen. He decided to leave the Mariners before the last year of his contract in 2004, giving up $8.5 million, citing his desire to be with his family in Japan. According to the Seattle Post-Intelligencer, however, Sasaki's real reason for returning to Japan was pressure from ownership, due to his "indiscreet philandering".

Sasaki resumed his career with the BayStars upon returning to Japan, where he pitched for another year. But in his second year back, nagging knee and elbow injuries resulted in his release from Yokohama and subsequent retirement. His last official appearance came as a cameo against the Tokyo Giants on August 9, 2005, as he struck out his longtime friend and rival Kazuhiro Kiyohara in a game played at Fullcast Stadium Miyagi in his hometown.

In addition to his Rookie of the Year award, Sasaki set several Japanese professional baseball records, including saves (45) and save opportunities (46) for a single season in 1998; he was twice selected to play in the All-Star game, and was selected to eight All-Star teams in Japan. Sasaki's 37 saves in his rookie season with the Seattle Mariners remained a Major League Baseball record for saves by a rookie until Neftalí Feliz broke it in 2010 with 40.
