Mariners vs White Sox MLB Betting Preview
Both Emerson Hancock and Sean Burke look like pitchers who’ve legitimately taken a step forward this season, which is why I like both the Mariners' moneyline and the under in this matchup. The weather helps too, temperatures in the mid-50s with wind blowing in slightly should continue to suppress offense.
Hancock, in particular, has shown dramatic improvement. The pedigree has always been there as a former first-round pick, and when those types of prospects finally break out, even later than expected, it tends to carry more credibility. Through this point in the season, Hancock owns a 25% strikeout-minus-walk rate, which is elite territory.
That number may come down somewhat, but the gains themselves look sustainable. Blending together expected FIP, xERA, and other predictive indicators, he’s graded out as a top-10 starting pitcher for me so far this season.
Sean Burke has improved as well. Last year, he projected closer to a below-average arm, but the underlying metrics have taken a major step forward, with his expected indicators now sitting below 4.00. I still give Hancock the edge, but both starters profile well enough to support a lower-scoring environment.
I make the total closer to 7.25, so I like the under 8 and would still play under 7.5 down to around -105. One of the stronger under looks on the board today, especially with weather conditions cooperating.
The bigger gap comes offensively. Seattle grades out far better than Chicago against right-handed pitching. I have the Mariners around a 120 wRC+ in the split, the best offense on the slate against righties today, even ahead of the Yankees, while the White Sox sit closer to an 89 wRC+, nearly a 30-point gap in offensive quality. Seattle also owns the bullpen edge, even with some moving pieces in relief.
Putting it all together — better starter, better offense, better bullpen, and favorable weather, I make the Mariners closer to -160 in this matchup. I played them up to -145 and still prefer the under alongside the Seattle side.
