Aaron Small was a professional baseball player who played as a pitcher in the Major League Baseball (MLB) for several teams. He began his career in 1988 when he was drafted by the Toronto Blue Jays in the 22nd round of the MLB draft. However, he did not make his MLB debut until 1994 when he played for the Blue Jays.

Small played for several teams during his career, including the Blue Jays, the Florida Marlins, the Oakland Athletics, the Arizona Diamondbacks, the New York Yankees, and the Kansas City Royals. He was primarily used as a relief pitcher, but he also started some games throughout his career.

Small's most successful season was in 2005 when he played for the Yankees. He had a record of 10-0 with a 3.20 earned run average (ERA) in 15 starts. This was a remarkable achievement for Small, who had struggled to establish himself as a regular player in the MLB for many years.

Small's success in 2005 was largely due to his ability to keep the ball in the strike zone and limit walks. He also had a good fastball and a solid changeup, which helped him to keep batters off balance. Small's success was a key factor in the Yankees' run to the playoffs that year.

Despite his success in 2005, Small was unable to replicate his performance in subsequent seasons. He played for the Royals in 2006 but was released after just four appearances. He then signed with the Yokohama BayStars of the Japanese Central League but struggled there as well.

Small retired from baseball in 2007 and has since worked as a coach and instructor. He has also been involved in charity work, including the Aaron Small Foundation, which supports children with cancer.

Overall, Aaron Small had a solid but unspectacular career in the MLB. His success in 2005 was a highlight, but he was never able to establish himself as a regular player for an extended period. Nevertheless, his perseverance and determination to succeed are admirable qualities that have earned him respect among his peers and fans.
