On May 22, 2002 — The Athletics send OF Jeremy Giambi to the Phillies in exchange for IF/OF John Mabry. The trade, viewed as one-sided for the Phils, especially by the statistically-oriented community, will be a good one for Oakland. Giambi will homer in his first two Phillie at-bats on the 25th, and be the first player in major league history to hit eight homers in each league before the All-Star break. He’ll finish the year with 20. That, plus Jason Giambi’s 41, will give the Giambi boys the record for homers by brothers in the same season, topping the 59 hit in 1937 by Joe DiMaggio (46) and Vince DiMaggio (13). However, Mabry will slug .523 in 89 games and help Oakland to a division title.
