White Sox: Foster is a high-leverage reliever
Those individuals who watched Matt Foster pitch in 2020 might disagree with his bullpen rise being considered a surprise after he posted a 2.20 ERA over 23 games as a rookie, with 31 strikeouts in 28 2/3 innings. But after a rough sophomore campaign, featuring a 6.00 ERA in 37 games, the right-hander is back with a 0.66 ERA in 13 games. He has incorporated an effective slider and curve into his previous fastball/changeup repertoire, and manager Tony La Russa loves his competitive fire late in games. Foster adds to a late-inning mix already featuring Liam Hendriks, Kendall Graveman, Aaron Bummer and the soon-to-be-arriving Joe Kelly.
