Masumi Kuwata

Kuwata quickly established his presence in the professional leagues, winning 15 games in his second year (1987) with a 2.17 ERA, the lowest in the league.

Major League pitcher Bill Gullickson played for the Giants in 1988–1989, and befriended Kuwata. Gullickson named his son Craig Kuwata Gullickson after Kuwata, and gave much advice to the Japanese pitcher. Kuwata has said his dream of playing in the Major Leagues came from Gullickson. However, many obstacles kept him from realizing this dream — including his great success in Nippon Professional Baseball. He won the Eiji Sawamura Award (the Japanese equivalent of the Cy Young Award) the same year, and won over ten games for six consecutive seasons starting in 1992.

Kuwata suffered a severe injury to his right elbow while attempting to catch a pop fly in June, 1995, ending his season. Kuwata had surgery in the U.S., and spent the rest of 1995 and all of 1996 in rehab. He made a comeback in 1997, winning 10 games, and 16 games in 1998, but his pitching had deteriorated considerably compared to the years before his injury, particularly with a loss of velocity off his fastball.

Kuwata considered retirement during the 2001 off-season, but Giants general manager Tatsunori Hara convinced him to remain on the team. On April 19, 2002, Kuwata pitched brilliantly in defeating Hanshin Tigers ace Kei Igawa by a score of 1-0, and showed he could still be an important part of the Giants' rotation.[1] Kuwata went on to have a banner year in 2002, posting a 2.22 ERA (lowest in the league), and winning over 10 games for the first time in four years. However, he pitched poorly from 2003-2006, appearing in a total of only 45 games (44 starts), while compiling an overall 9-16 record during those four years.

Kuwata pitched 118 complete games during his career in Japan.[2]

At the end of the 2006 season, Kuwata surprised fans by announcing his intention to play in the Major Leagues.[3] In December 2006 Kuwata signed a minor league contract with the Pittsburgh Pirates as a 38-year-old rookie, ending his 21-year stay with the Yomiuri Giants. Despite interest from the Boston Red Sox and the Los Angeles Dodgers, Kuwata chose Pittsburgh because he thought the Pirates offered him the best opportunity to pitch in the majors.

Kuwata participated in spring training with the Pirates, but injured his right ankle, ending his hopes of making their Opening Day roster. The Pirates placed him on their Triple-A Indianapolis Indians roster as a disabled player, giving him a chance to work his way up to the majors.

On June 9, 2007, Kuwata was promoted to the Pittsburgh Pirates after reliever Salomón Torres was placed on the disabled list. He became the first Japanese player in Pirates team history. He made his Major League debut June 10, 2007[4] in a game against the New York Yankees. At that time he was 39 years old, which was the oldest debut with the exception of Satchel Paige and Diomedes Olivo in the post-World War II era. He gave up two runs in 2 innings on a home run to third baseman Alex Rodriguez.

On August 14, the Pirates designated Kuwata for assignment.[5] The Pirates outrighted him to Triple-A on August 17 but Kuwata refused the assignment. Afterwards, he returned home to Japan.

In December 2007, Kuwata signed a minor league contract with the Pirates for the 2008 season. The contract included an invitation to spring training with the team.

Kuwata announced his retirement from baseball on March 26, 2008 after not making the team out of spring training.[6] Upon announcing his retirement, the Pittsburgh Pirates offered Kuwata a coaching position with the club, but he declined.
