White Sox Sign Austin Slater

The White Sox announced the signing of outfielder Austin Slater to a one-year deal. The Ballengee Group client is reportedly guaranteed $1.75MM and can unlock another $500K in performance bonuses. Slater would receive $50K in his 50th game and $75K apiece at 75 and 100 games. He’ll collect $50K for his 100th, 150th and 200th plate appearance and would earn another $75K each at 250 and 300 trips to the dish.

Slater, 31, was an eighth-round pick by San Francisco out of Stanford during the 2014 draft. The outfielder spent more than a decade in the Giants organization as he made his big league debut in 2017 and remained with the club through last season. In the first three seasons of his career, Slater was a decent but unspectacular fourth outfielder for San Francisco, slashing a combined .254/.335/.368 in 544 total plate appearances during that time. While primarily an outfielder, he also received occasional time at first base and even made token appearances at both second and third base off the Giants’ bench.

The outfielder broke out during the shortened 2020 season, however, with a 150 wRC+ and a .282/.408/.506 slash line in 104 trips to the plate while appearing in 31 of the club’s 60 games. That leap forward offensively earned Slater an expanded role over the next few years, and from 2021 to 2023 he became a regular for the Giants against left-handed pitching. While he was still generally shielded from righties, Slater slashed a respectable .257/.345/.412 in 343 games from 2021 to 2023. That’s good for a respectable 113 wRC+, and across those 838 plate appearances he walked at a 10.5% clip, swatted 24 homers, and swiped 29 bases despite frequent trips to the injured list cutting down on his playing time over the years.

Unfortunately for Slater, his production cratered in 2024. The outfielder hit just .209/.321/.266 (76 wRC+) overall in 212 trips to the plate this year while bouncing between the Giants, Reds, and Orioles. Even more surprisingly, the outfielder actually carried reverse splits this year after years of feasting on left-handed pitching. While he enjoyed a 141 wRC+ against lefties from 2020 to 2023, Slater hit just .188/.310/.231 against them in 142 plate appearances this year. Dismal as that overall production last year was, there is a silver lining in Slater’s performance. Once he arrived in Baltimore on the day of the trade deadline, he looked much more like the player he’s been throughout his career. In 79 plate appearances…
