Ex-MLB Player Jeremy Giambi Dead At 47, Officials Suspect Suicide

Ex-MLB player Jeremy Giambi — who played in the MLB from 1998 to 2003 — has passed away, TMZ Sports has learned. He was 47 years old.

Giambi played for the Royals, Athletics, Phillies, and Red Sox over the course of his career … earning a .263 batting average and hitting 52 home runs and 209 runs batted in.

His best season came in 2001, when he played in 124 games and had 12 homers.

Jeremy is the brother of Jason — the American League MVP in 2000, who played for the Athletics, Yankees, Rockies and Indians.

Giambi was portrayed in the 2011 Brad Pitt flick “Moneyball” … and was played by actor Nick Porrazzo. His character was depicted as a partier and disruption during his time with the A’s … and a scene shows him eventually being traded to the Phillies.

Giambi was part of the most memorable baseball moments of the past few decades … when Derek Jeter made a spectacular play to throw him out at home plate in the 2001 American League Divisional Series.
