Oakland Athletics: Brothers That Have Played For The A’s

Jason Giambi (1995-2001/2009) and Jeremy Giambi (2000-2002)

Older brother Jason Giambi made his Major League debut in 1995, hitting just .256 with 6 home runs in 54 games. He became the Athletics’ regular first baseman after Mark McGwire was dealt to the Cardinals in 1997 and took off as a team leader and producer. Jason hit .295 with 27 home runs in 1998 and .315 with 33 homers in 1999. His .300+ hitting continued in 2000 with a .333 average and 29 home runs. He was the 2001 MVP with a .342 batting average, and league-leading 47 home runs.  After leaving for the Yankees as a free agent in 2002, Jason was back with the Athletics for the 2009 season but after hitting only .209, he was released in August.

For his career, Jason was a five time All-Star (twice with the Athletics) and finished a 20-year career with 440 homers.

Younger brother Jeremy was acquired by the Athletics via trade with the Royals, where he had served a backup role for parts of two seasons. On May 8, 2000, Jeremy and Jason became the eighth set of brothers to hit a home run in the same game.

In his three seasons with the A’s, Jeremy batted a respectable .272 in 270 games, serving mostly as a DH or left fielder. In 2002, the A’s parted with Giambi in a trade to the Phillies. Overall, Jeremy had a six-year MLB career with four different teams. Jeremy’s greatest legacy with the Athletics is probably the 2001 ALDS against the Yankees and not sliding at home in Game 3.
