White Sox signed LHP Sean Newcomb to a one-year, $4.5 million deal.
Newcomb had a mini breakout in 2025, posting a 2.73 ERA and 23.3 percent strikeout rate in 92 1/3 innings across 48 appearances (five starts) with the Red Sox and the Athletics. Boston cut back heavily on his four-seam fastball usage, adding a cutter to his arsenal and also increasing his sinker usage, and the three fastball variations worked wonders for Newcomb. He was one of the top left-handed relievers on the market and a good get for the White Sox.
