It's another move to aid the pitching staff from new White Sox' general manager Chris Getz. After the White Sox finished fourth in the American League Central a season ago, he's come in and turned over the roster in various ways.

The team let injured stalwart Liam Hendriks go and then traded away ace reliever Aaron Bummer. They acquired multiple arms from the Atlanta Braves, including Mike Soroka, and then signed Chris Flexen and Erik Fedde.

As for Brebbia, the 33-year-old has appeared in the majors in six separate seasons with the St. Louis Cardinals and San Francisco Giants. He's been mostly a reliever, but did make 21 starts for the Giants over the last two years. He made an MLB-high 76 total appearances in 2022 and appeared in 40 games this past season with a 3.99 ERA.

Lifetime, he's 15-15 with a 3.42 ERA. He figures to be a bullpen arm for the White Sox, but with his starting experience, he offers flexibility and options, likely as an "Opener."

The White Sox lost more than 100 games last season and haven't made the playoffs since the 2021 season. They could still have more moves to come this offseason; it's long been thought of that they will trade ace pitcher Dylan Cease before the beginning of the season.
