Detroit Tigers ace Tarik Skubal is toeing the rubber against the Arizona Diamondbacks at Chase Field today, and the back-to-back AL Cy Young winner will look to make it back-to-back wins to open the season.

My top Tigers vs. Diamondbacks predictions and MLB picks are calling for just that, with Arizona countering with veteran Zac Gallen this afternoon.

Who will win Tigers vs Diamondbacks today: Tigers -1.5 (48 cents)

With Arizona Diamondbacks starter Zac Gallen’s ERA and xFIP climbing in each of the past three seasons before allowing four runs on five hits and a pair of walks through four frames in his first 2026 start, I’m anticipating a long season ahead for the veteran righty.

It’s just the opposite for Detroit Tigers ace Tarik Skubal, with the star southpaw ranking second among qualified starters in ERA and xFIP since the beginning of the 2024 campaign.

Additionally, the Arizona offense is off to a ho-hum start with a 23rd-ranked xwOBA.

COVERS INTEL:

Arizona righty Zac Gallen surrendered the 10th-highest barrel percentage among qualified starters in 2025, and he allowed three through just four innings in his 2026 debut.

Tigers vs Diamondbacks Over/Under pick: Under 8.5 (58 cents)

I’m anticipating Skubal doing the heavy lifting to keep this total Under the number, as he’s allowed three earned runs or fewer in 26 of 32 starts since the beginning of last year.

Additionally, even with Gallen in a clear decline, the Tigers enter with a 25th-ranked wOBA alongside a middling 15th-ranked xwOBA through five 2026 games.
