White Sox Designate Lucas Sims For Assignment

The White Sox shuffled up their bullpen Thursday, announcing that veteran righty Lucas Sims has been designated for assignment. Right-hander Tyler Davis has had his contract selected from Triple-A Charlotte and will join the big league relief corps.

Sims, 32 next month, pitched 10 innings for the South Siders prior to this morning’s DFA. He was tagged for seven runs (five earned) on nine hits, seven walks and a hit batter. He fanned 10 of his 46 opponents (21.7%), but his perennially spotty command also led to 17.4% of his opponents reaching base without even needing to put a ball in play.

The White Sox added Sims on a minor league deal over the winter. He had a nice spring, firing six shutout innings with three hits, three walks and eight strikeouts, but didn’t make the Opening Day roster. He began the season in Charlotte and tossed a scoreless frame before being selected to the majors when the Sox parted ways with Rule 5 pick Jedixson Páez.

A veteran of 10 partial major league seasons, Sims has more than six years of service time. He was a useful middle relief and eventual setup arm at his peak in Cincinnati, pitching to a combined 3.93 ERA in 183 1/3 innings from 2019-23. Sims punched out a hearty 31.9% of opponents in that time but was far too prone to free passes, issuing walks at a 12.2% clip.

Sims collected 39 holds and four saves in 2023-24, but a 2025 stint with the Nationals saw his shaky command erode to untenable levels. Sims walked more than 19% of his opponents (14 of 72) and plunked another seven batters before being cut loose in Washington. This year’s command was better than that low point, but Sims has walked or plunked more than 15% of the 1429 batters he’s face in the majors. It’s unlikely he’ll ever end up with even average command over a sample of any note.

The White Sox will have five days to trade Sims or place him on outright waivers. If they go the waiver route, that’d be an additional 48-hour process, meaning his DFA will be resolved within a maximum of one week.

As for Davis, he’ll be making his major league debut the first time he takes the mound. The 27-year-old was never drafted, instead signing with the Sox out of the independent Pioneer League in 2024, when he played for the Oakland Ballers. He’s a Sam Houston State product who’s pitched 103 innings in pro ball since signing. In that time, Davis has logged a 3.41 earned run average with a 27.1% strikeout rate and 12.4% walk rate.

Davis has some experience as a first baseman as well, having worked as a two-way player in college. However, he’s focused solely on pitching in affiliated ball and will come to the ChiSox with a four-seamer that’s been sitting 96.4 mph in Triple-A, a splitter that’s averaged 86.2 mph and a slider at nearly the same velocity as that split.
