Action PRO's White Sox vs Guardians Best Bet

Parker Messick Over 6.5 Strikeouts
FanDuel Logo

By Action PRO

Action PRO projects Parker Messick to record 6.85 strikeouts, yielding an immediate value edge against the current 6.5 line.

Messick has been exceptionally comfortable against this Chicago lineup, dominating them across three prior outings this season with a pristine 2.29 ERA and 21 strikeouts over 19.2 innings.

His overall form remains sharp as the season winds down, demonstrated by a massive 12-strikeout display against the Detroit Tigers on September 5.

Messick has eclipsed his strikeout projection in 7 of his last 10 starts. Even with a minor cool-down during three of his last four appearances, his overall swing-and-miss stuff makes Over 6.5 Strikeouts the top play for Wednesday's divisional finale.

Pick: Parker Messick Over 6.5 Strikeouts (-110 or Better)

Yankees ML | Ben Rice Prop

By Ryan Minion

The Twins and Yankees will square off on Wednesday afternoon in another spot where I heavily favor targeting player prop markets.

33-year-old veteran left-hander Carlos Rodon will get the start for New York, while righty Zebby Matthews will take the mound for the Twins.

In what has been an up-and-down 2026 campaign for Minnesota’s right-hander, with Matthews currently posting a 4.98 ERA so far, I expect this to be another tough challenge against a red-hot Yankee lineup.

In this case, I expect the Yankees’ lefty slugger Ben Rice to have a monster day at the plate versus the Twins’ 26-year-old.

In eight previous encounters between the two, New York’s 27-year-old has recorded four hits – two of which were for extra bases, with a double and a home run.

The Yankees’ youngster put on a ton of muscle in the offseason and has quickly established himself as one of baseball’s premier power hitters — ranking seventh in all of baseball with 38 HRs in 2026 thus far.

Matthews has struggled to keep the ball in the yard for most of the season, allowing 23 homers in fewer than 120 frames on the mound.

I expect this to be a highly favorable matchup for Rice given his remarkably impressive pull-heavy left-handed power bat.

New York’s Designated Hitter is also on an absolute tear right now, so he enters Wednesday’s contest in phenomenal form.

That said, I favor backing Rice to exceed an alternate 2.5 HRR total as my primary betting angle ahead of Wednesday’s American League showdown.

As a secondary wager, I'm willing to take a shot on the Yankees moneyline as well given their far superior lineup and a rather significant edge on the mound on Wednesday afternoon.

Picks: Ben Rice Over 2.5 HRR (+125 or Better) | Yankees ML (-150 or Better)

Brandon Marsh Over 0.5 Walks
FanDuel Logo

By Derek Carty

THE BAT X is forecasting 0.50 walks for Brandon Marsh. Oddsmakers are implying 0.30 walks, so I believe there is value on this prop.

If you take the over, you'd be projected to win 41% of the time, for a 54% ROI and an expected value of $54.20 (based on a $100 wager).

This play is good down to at least +171.

Pick: Brandon Marsh Over 0.5 Walks (+171 or Better)
