Ryan Minion's Tigers vs White Sox Prediction
By Ryan Minion
Though Tigers’ lefty Framber Valdez started his first season in Detroit in lackluster form, the former Astro seems to be rediscovering the previous elite form that he had on the mound throughout his last few years pitching for Houston.
Detroit’s Dominican left-hander has been unbelievably impressive on the bump over the course of his first eight-plus seasons in the Big Leagues. In eight seasons pitching for the Astros, Valdez recorded an ERA below 3.40 on average.
While the Tigers’ 32-year-old has recorded a 4.28 ERA to start his 2026 campaign, Valdez’s inflated metrics on the mound this season are largely due to a couple of outlier performances amongst several elite starts.
The Tigers’ left-hander allowed a whopping eight earned runs (ER) across just five frames in one of his first starts of the season and also allowed seven ER through just three innings pitched (IP) in early May.
Aside from his two volatile performances on the mound, Valdez has been pretty remarkable otherwise, having recorded seven quality starts (QS) across his first 11 outings this season.
Like Valdez, White Sox lefty Anthony Kay has been a model of consistency throughout the first few months of his 2026 campaign, minus a couple of outlier performances in which he got rocked, including his having allowed eight ER in under four frames on the mound.
Chicago’s 31-year-old is in scorching form in May thus far, with Kay having recorded a 1.98 ERA across five starts this month and not allowing more than two ER in a start since April.
A deeper look into both starters' metrics on the season reveals the value in doing your due diligence when evaluating a player’s form, and even more so when it comes to assessing starting-pitching matchups.
I fully expect runs to come at a premium on Saturday afternoon in Chicago in what sets up to be a phenomenal lefty pitching duel featuring two starters boasting versatile pitching arsenals.
Pick: NRFI (-160 or Better)

Tony Sartori's Royals vs Rangers Best Bet
By Tony Sartori
Like Kansas City, Texas has struggled offensively this season. Entering this matchup, the Rangers rank 25th in runs scored per game, 24th in hits per game, 22nd in on-base percentage, and 23rd in OPS.
Texas has also struggled against Seth Lugo. In 52 combined plate appearances against the right-hander, the current Rangers roster owns a .106 batting average, .234 slugging percentage, and a .197 weighted on-base average.
With two starters in strong recent form and both offenses ranking in the bottom third of the league in most key categories, this profiles as a low-scoring matchup.
Pick: Under 8 (-120 or Better)

Sean Paul's Cubs vs Cardinals Best Bet
By Sean Paul
The Cubs finally snapped their 10-game losing streak with a pair of wins in Pittsburgh. They'll aim to get on a hot streak against their heated rivals from St. Louis.
Due to injuries and poor-performing starters, the Cubs needed someone to emerge — and Ben Brown has answered the call. In four starts this year, Brown has allowed one run or fewer in all but one, and he reached six innings and 84 pitches in his last start, both season highs.
Brown is great at limiting damage. He's given up just one homer in 44 2/3 innings and generates close to 80% of his outs via the strikeout or ground ball. His pitch mix is more reliever-like. He throws a four-seamer mainly to left-handed hitters, his sinker to righties and a knuckle curve to put away hitters.
His ERA sits at a strong 2.01, with a 2.85 xERA and a 2.26 FIP, which support his dazzling ERA.
During the Cubs' losing skid, their bats didn't come to play.
In May, Chicago ranks 20th in MLB with a 90 wRC+, 28th in batting average and 21st in home runs. The only thing this offense does well is draw walks, recording a league-best 12% walk rate.
Michael Busch and Ian Happ have done most of the offensive heavy lifting. Busch has a 176 wRC+ in May, and Happ leads the team with five homers.
However, Nico Hoerner, Alex Bregman and Seiya Suzuki have struggled mightily of late. Suzuki recorded three hits in the series opener on Friday, but each of the three players posted a wRC+ below 100 over their past 25 games.
With three such proven players, and considering how good the Cubs offense was in March and April, I imagine things will get back on track.
The Cardinals were supposed to be rebuilding, but they sit in second place in a strong NL Central.
They'll hand the ball to one of the weak links in their rotation, Kyle Leahy. The transition to the rotation has been bumpy for Leahy, who owns a 4.44 ERA with a 6.30 xERA and a 4.94 FIP.
None of the batted-ball data looks good for Leahy, either. Opponents have a .300 xBA, while he's running a 50% hard-hit rate (fourth percentile) and a 92 mph average exit velocity (third percentile).
The Cubs should have a field day against Leahy.
Offensively, the Cardinals are another below-average unit. Unlike the Cubs, they have a much lower ceiling.
They rank 21st in wRC+ this month and have hit just 20 home runs. The only three trustworthy hitters on St. Louis' roster are Jordan Walker, who is finally realizing his potential, Alec Burleson, a consistent contact hitter, and Ivan Herrera, who hit the go-ahead homer on Friday.
There just isn't a ton of talent in this Cardinals lineup. Walker is a baller, and the other two are solid, but after all, this was supposed to be a rebuilding season.
I find some real value in taking Brown at -136. He could be a frontline pitcher for this Cubs team moving forward, while Leahy's days in the rotation could be numbered. I want the better pitcher in a matchup between two teams with below-average offenses.
Pick: Cubs ML (-150 or Better)

Matt Trollo's Diamondbacks vs Mariners Prediction
By Matt Trollo
Although he struck out only four last time out against a contact-prone Kansas City lineup, Bryan Woo had struck out 26 of his previous 67 batters with a 14.0 SwStr%.
While his 23 K% on the season is 4.1 points below last season, he’s still striking out 29.1% of batters faced at home, just 0.5 points below last year, and that’s because the Mariners boost strikeout rates by 15% for LHBs and 21% for RHBs.
That means the Diamondbacks projected lineup that averages a 19.8 K% vs RHP since last season boosts up to at least 22.7%, and that’s only if they were all left-handed. That's also projecting Arenado's return (14.6% vs RHP since 2025).
I have the true boost (projected RH & LHBs) around 18% for this game, with a further 4% boost for umpire David Rackley.
That brings my overall strikeout rate expectation for Woo close to 30% for this start. Averaging 23 batters faced, I’d project him for closer to seven than six and see some value in this number up to -120.
Pick: Bryan Woo Over 5.5 Strikeouts (-120 or Better)
