Chicago White Sox (Erick Fedde) at Tampa Bay Rays (Nick Martinez) Prediction & Betting Pick | MLB Regular Season July 31, 2026

Chicago–Tampa sets up as one of those spots where the matchup, the bullpen situation, and the pitching profile all point in the same direction. Nick Martinez is exactly the type of arm you want backing when the Rays are stretched thin — efficient, low‑walk, and comfortable working deep into games. Tampa burned through ten relievers over the last two games and will be without both Steven Matz and Bryan Baker tonight, so Martinez isn’t just likely to get a long leash… he’s required to. That alone gives this play a ton of value.

Martinez has been sharp lately, especially with his command. A 3.1% walk rate and a 61% first‑pitch strike rate over his last three outings show a pitcher who’s attacking hitters and staying ahead in counts. When you pair that with his season-long 4.2% walk rate — elite territory — you get a profile built for efficiency. And efficiency is exactly what you need when backing an outs prop.

The matchup helps too. The White Sox lineup is dangerous at home, but they lose a lot of punch on the road. Their road splits drop them into the bottom half of MLB, and they’ve been letting opposing right-handers work deep into games. Six of the last nine RHPs they’ve faced have gone 6+ innings, and several of those arms weren’t nearly as efficient as Martinez. If they’re letting average righties stretch out, Martinez should have no problem doing the same.

Chicago’s offense has power, but they’re also strikeout-prone and streaky. They’ve punched out 961 times already and sit at a 2.31 K/BB ratio — not ideal against a pitcher who lives in the zone and forces early swings. Martinez doesn’t need strikeouts to get outs; he needs weak contact and quick innings, and the Sox have been giving that away to righties for weeks.

The Rays’ defense also gives him a boost. Tampa ranks second in MLB in defensive efficiency, converting 72.1% of balls in play into outs. When you’re backing an outs prop, that matters. Martinez doesn’t have to be perfect — he just needs the defense behind him to keep innings clean, and Tampa has been doing exactly that.

On the other side, Erick Fedde has been hittable all season — 4.87 ERA, 1.436 WHIP, and nearly 9.3 hits per nine. Tampa’s offense isn’t elite, but they’re patient and they put the ball in play. That means Martinez should get run support, which keeps him in the game longer. The Rays don’t have the luxury of pulling him early tonight anyway, but a lead makes that leash even longer.

Chicago’s bullpen is also a mess — 20 blown saves, bottom‑tier inherited runner numbers, and one of the lowest hold totals in baseball. If Martinez hands the Rays a lead, they’ll protect it better than the Sox would. That stability gives Tampa every incentive to let Martinez work through six innings if he’s rolling.

Given the depleted Rays pen, Martinez’s elite command, Chicago’s road struggles, and the matchup history of righties working deep against this lineup, the path to 18 outs is wide open. He should have every opportunity to get there.
