There’s not been much for fans on the South Side of Chicago to get excited about of late. The club’s lengthy rebuild in the 2010s assembled a core that included well-regarded pieces like Lucas Giolito, Dylan Cease, Eloy Jimenez, Tim Anderson, Yoan Moncada, and Luis Robert Jr. but did not translate to much success on the field; the group ultimately made it to the playoffs in 2020 and ’21 but lost in the first round both years before regressing to an 81-81 record in 2022 and kicking off the latest rebuild.
Since then, White Sox fans have watched that core get dismantled, whether via trades or declined club options, and breakout ace Garrett Crochet followed them out the door over the offseason. Crochet’s excellent pitching performances were the one highlight of the White Sox season this side of the Campfire Milkshake, so that left fans with little to look forward to in 2025… or so we thought. In reality, the White Sox seem to have replaced their dominant ace with another potential front-of-the-rotation arm who came from the most unlikely of places: the Rule 5 draft.
Righty Shane Smith was plucked from the Brewers’ organization and made Chicago’s Opening Day rotation out of Spring Training. It was difficult to know what to expect from Smith, given that an organization as well-regarded for its pitching development as Milwaukee was comfortable leaving the righty unprotected this past winter. That’s quickly proving to have been a mistake. Through his first ten starts of the season, Smith has posted a sterling 2.36 ERA that stands as the eleventh-best figure among qualified starters this year, just ahead of Paul Skenes.
ERA is an imperfect estimator of talent, of course, and Smith’s personal figure is deflated by the fact that a six-run, five-inning outing against the Cubs saw five of those runs scored as unearned. Even setting ERA aside, however, his season has been an impressive one so far: a 3.32 FIP (26th) and 3.57 xERA (t-29th) lend credence to the idea of Smith as a potential front-end arm, even if he isn’t quite in the Cy Young conversation based on those more advanced metrics. Have the White Sox truly found a diamond in the rough, or is Smith’s hot start to his career just a flash in the pan?
Overall, Smith’s profile is a solid one, but there are signs that it’s closer to that of a league average starter than anything else. His 22.0% strikeout rate and 8.1% walk rate are both middle of the pack, and a 45.3% ground ball rate is above-average but not exactly elite. His .259 BABIP and 5.9% home run to fly ball ratio are both top-of-the-scale, but neither of those figures are particularly skill-interactive or sustainable, particularly for a hurler who rarely generates soft contact. If anything, those figures are potential red flags that indicate risk of future regression. Smith’s 3.96 SIERA and 97 xFIP- paint him as a roughly average MLB starter as well, offering all the more reason to think he might regress.
There are reasons for optimism as well, however. Smith generates swinging strikes at a well above average clip, which could be a sign for strikeout potential beyond the average rates that he’s shown to this point. An uptick in strikeouts would raise the floor on his whole profile in a way that could allow him to keep producing at this level. Even without that, however, it’s fair to point out that there have certainly been pitchers who have found consistent MLB success over the years despite mediocre underlying data. Smith’s metrics are better than, as one example, those of Javier Assad on the other side of town. Assad has a career 3.40 ERA across nearly 300 innings in the majors despite lackluster metrics, and that’s a figure any team would happily take from a Rule 5 pick.
How do MLBTR readers think Smith will pan out going forward? Will he be able to find another gear and keep producing like a front-half of the rotation arm, will he settle in as more of a reliable back-end starter, or will this hot start prove to be a total mirage? Have your say in the poll below:
