Spring Training predictions for February 23

Picks
Mariners Mariners moneyline+102
Athletics Athletics moneyline+140
Phillies Phillies moneyline+120

Pick #1: Mariners moneyline

+102 at DraftKings

Logan Gilbert is among baseball's top arms, and the Seattle Mariners right-hander makes his spring debut against the Los Angeles Dodgers today.

That's a tough sell, but it's why we're getting a good number on Seattle. With Landon Knack on the bump for L.A., I'll go with the better starter.

Plus, the Mariners boasted a better bullpen in 2025, and I'll take that edge if Gilbert can leave with the lead intact.

Pick #2: A's moneyline

+140 at DraftKings

I generally prefer the A's lineup to the San Francisco Giants. So, getting plus money against right-hander JT Brubaker is a boon.

Obviously, it depends on the respective lineups, but if we get Lawrence Butler, Nick Kurtz, Tyler Soderstrom, Brent Rooker, and Shea Langeliers — even if only for an inning or two — that could be enough.

That alone makes the value at +140 worth a look.

Pick #3: Phillies moneyline

+120 at DraftKings

The Philadelphia Phillies are going the no-name route with right-hander Alan Rangel toeing the rubber against the Washington Nationals opposite Jake Irvin.

The 28-year-old made his MLB debut in 2025 as a reliever, which explains why the Nats are favored. But Irvin was one of baseball's least effective starters last summer, boasting a 5.70 ERA across 33 starts.

While both teams will go to the pen relatively early, I won't be surprised if Philly's bats jump on the right-hander out of the gate.
