David Allan Aardsma (; born December 27, 1981) is an American former professional baseball pitcher, currently serving in the Toronto Blue Jays front office as a coordinator of player development. He played in Major League Baseball (MLB) from 2004 to 2015 for the San Francisco Giants, Chicago Cubs, Chicago White Sox, Boston Red Sox, Seattle Mariners, New York Yankees, New York Mets, and Atlanta Braves. Amateur career Aardsma was born in Denver, Colorado, and attended Cherry Creek High School in Colorado, graduating in 2000. He subsequently attended Pennsylvania State University in his first year of college. He transferred to Rice University in 2001, where he remained for the rest of his college tenure. Playing for the Rice Owls baseball team, Aardsma set school single-season and career records in saves in 2003. In the 2003 College World Series, he earned two wins and a save as the Owls won their first national championship. In 2002, while playing collegiate summer baseball for the Falmouth Commodores in the Cape Cod Baseball League (CCBL), Aardsma was named a league all-star, posting a 0.68 ERA with 45 strikeouts over 26.2 innings. In 2010, he was inducted into the CCBL Hall of Fame. Professional career San Francisco Giants The right-hander was drafted in the 1st round (22nd overall) of the 2003 Major League Baseball Draft by the San Francisco Giants. He went to the San Jose Giants (Single-A), where he posted a 1.96 ERA while striking out 28 in about 18 innings. He made the major-league roster in 2004, skipping Double-A and Triple-A, and made his debut in the season's second game. In his major league debut, in front of friends and family at Minute Maid Park, he pitched two innings, allowing three hits and walking one, to earn his first MLB win. In his first six appearances, he had a 1.80 ERA; unfortunately his success did not last as his ERA ballooned to 6.75 after 11 appearances. After giving up two runs in one inning on April 20, he was sent down to Fresno, the Giants Triple-A team, the next day. He was called up six more times throughout the season. Aardsma's route through professional baseball has been somewhat unusual, given that after making the leap from Single-A to the Giants, he was demoted to Triple-A and then subsequently started the 2005 season in Double-A with the Norwich Navigators.
