Bummer gets the largest extension in MLB history given to a non-closing reliever who has yet to qualify for salary arbitration, according to Bob Nightengale of USA TODAY Sports.
The 26-year-old authored a 2.13 ERA in 58 games for Chicago last season. His 27 holds put him in a tie for sixth-best among American League relievers.
White Sox assistant general manager Jeremy Haber said the team and Bummer’s agent started exchanging figures in late January, according to James Fegan of The Athletic.
Garcia hit .279 with eight home runs and 40 RBIs in 140 contests for the South Siders during the 2019 campaign.
