Detroit Tigers (72-81) at Chicago White Sox (78-75) | Friday, September 18, 2026 | 6:40 PM CT | Rate Field, Chicago, IL
Thursday’s 3-1 win over Framber Valdez felt like exactly the response this team needed after losing first place to Cleveland earlier in the week. As a Sox fan, I’ll take a scrappy, low-scoring win against a legitimate arm any day, and tonight Chicago hands the ball to a rookie whose season line looks a lot worse than he’s actually pitched. Let’s talk about why David Sandlin’s 5.64 ERA is more of an accounting problem than a talent problem, and what that actually means against a Detroit team still riding real momentum of its own.
Here’s my real breakdown of tonight’s matchup — the underlying numbers and tactical wrinkles that matter more than a straight odds recap.

The Real Story Behind Sandlin’s Ugly ERA
Here’s the number that gets lost every time Sandlin’s name comes up: a 5.64 ERA looks like a pitcher who’s struggling to hold his own in the majors. His FIP, though, sits at a much more respectable 3.83 across 21.2 innings — and the gap between those two numbers isn’t random noise. Sandlin had one genuinely disastrous outing where he allowed eight earned runs across just four innings. Strip that single start out, and the rest of his sample looks like a pitcher who’s actually earning his spot in this rotation, not just surviving in it.
That matters heading into tonight because Sandlin is a 25-year-old rookie making just his fifth career start, acquired back in February in the trade that also brought Jordan Hicks to Chicago. This is a young arm still figuring out the league, and tonight is a real chance to show the disaster start was the outlier, not the identity.
Detroit’s Own Rookie Question Mark
Andrew Sears enters tonight with his own mixed bag of results — a 4.50 ERA and 4.10 FIP across two starts as a member of Detroit’s rotation, striking out nine over 10 innings but also getting hit for 11 hits, including a home run, with three walks and a pair of hit batters mixed in. He’s a 24-year-old who’s been solid at times but hasn’t put together a complete outing yet. If tonight turns into a battle of two unproven rookie arms, the team that gets more from its bullpen behind them probably wins.
The Prop Trends Worth Knowing
A couple of situational numbers stand out tonight. Randal Grichuk has hit the over on hits in 17 of his last 20 games, a genuinely hot stretch that makes him one of the more reliable bats in Chicago’s lineup right now. On the flip side, Munetaka Murakami has gone under on the combined hits-runs-RBI mark in 19 of his last 25 games — a real cold stretch worth being honest about, even for a hitter who’s provided real power at other points this season. If Chicago’s offense needs a spark tonight, Grichuk feels like the more likely source than Murakami based on recent form.
What’s Actually at Stake
Chicago is still chasing first place after Cleveland’s late-week surge knocked the White Sox out of the division lead for the first time since July. A series win here doesn’t fix that by itself, but it keeps the pressure on and prevents any further slippage in the standings during a stretch that’s already tested this team’s depth. Detroit, for its part, is still fighting for playoff positioning of its own, which means neither team is treating this as a routine September series.
What Actually Decides Tonight
I think this comes down to whether Sandlin’s disaster start was the exception or a real warning sign. Given the gap between his ERA and FIP, and the fact that one bad outing is doing most of the damage to his numbers, I like his chances to give Chicago a real, competitive start tonight. Combine that with Grichuk’s hot bat and a Detroit rookie who’s still finding his footing of his own, and I think the White Sox have a genuine edge here.
As a White Sox fan, I like this matchup a lot more than the season ERA line suggests on the surface. Give me Chicago taking control of this series tonight.
