The Cleveland Guardians have won five straight and face the Detroit Tigers for the second meeting of a three-game AL Central showdown at Comerica Park on Wednesday, September 17.

My Guardians vs. Tigers predictions and top MLB picks are calling for Detroit veteran Jack Flaherty to lead the way in snapping Cleveland’s winning streak.

Guardians vs Tigers prediction

Guardians vs Tigers best bet: Jack Flaherty Over 5.5 strikeouts (-105)

Detroit Tigers righty Jack Flaherty was sharp in his past start against the high-powered New York Yankees, notching seven strikeouts across five frames, and the Cleveland Guardians have an above-average strikeout percentage against righties for the campaign.

While game-to-game inconsistency has been part and parcel with Flaherty this season, he’s been partial to punchouts with a fifth-ranked 10.56 K/9 and 10th-ranked 27.8 K% among qualified starters.

Additionally, Flaherty’s 29.6 called-plus-swinging-strike percentage ranks eighth.

The veteran also sports an unsustainably low 66.0% strand rate and an unsustainably high .342 BABIP across 17 starts dating back to late June, so his inflated 5.42 ERA isn’t a truly accurate portrayal of his mound prowess.

Flaherty sports a much more respectable 3.75 xFIP during the stretch, and he fanned six or more batters in 11 of those 17 outings.

Guardians vs Tigers same-game parlay (SGP)

In addition to Flaherty pitching well, I also expect Cleveland starter Gavin Williams to continue limiting opposing lineups. He’s turned in a tidy 3.16 ERA this season and has surrendered two runs or fewer in eight of his past 10 starts for an even better 2.28 mark.

Plus, the Guardians have cashed the Under in 34 of their last 54 away games (+13.30 Units / 22% ROI)

The final leg of this same-game parlay calls for Tigers outfielder Riley Greene to drive in a run, and he’s up to 108 RBI for the campaign while posting an eye-popping .377 wOBA, .295 ISO, and .897 OPS against righties.
