Best MLB prop bets April 1: Back Fernando Tatis Jr. and Tigers starter Casey Mize on Tuesday

MLB prop bets

Tuesday’s 13-game MLB slate provides us with plenty of player prop options.

The pregame narrative: I’m going back to two players I recommended last night (Mike Trout, Fernando Tatis Jr.) and have a best bet on Detroit Tigers right-hander Casey Mize.

Check out the best MLB prop bets for April 1.

Best bet: Mize over 4.5 Ks (-139)

Embed: #112046

It’s early, of course, but the Seattle Mariners’ 28.4 K% (fifth-highest in MLB) can’t be ignored. 

Not after they had the highest K rate in MLB last season. 

Mize was once a big name — the 2018 No. 1 overall pick — and he’s looking to become that again after working his way back to the big leagues last season. 

The right-hander missed all of 2023 and was limited to two starts in 2022. 

He made 22 appearances last season (20 starts) and was not overly impressive (below-average K rate, high walk rate, 4.49 ERA). 

But he delivered above-average velocity and a strong groundball rate. And he was sensational this spring. 

  • 1.89 ERA in 6 appearances
  • 1.00 WHIP
  • 25 Ks in 19 IP 

Take spring stats with a grain of salt, but reports had Mize flashing increased velo and his splitter (his top putaway pitch in 2024) got rave reviews. 

At pitcher-friendly T-Mobile Park, this is about as soft a landing as you could ask for in a season debut.

Key stat: The Mariners are last in MLB in contact rate.

Best MLB picks

Trout over 1.5 total bases (+114): Trout has followed up a scorching spring (1.026 OPS, three homers) with next to nothing so far.

The three-time MVP has one hit (a single) and a .176 on-base percentage through four games. He’s 0-for-4 against this line. 

Trout hasn’t been hitting the ball with authority, but he’s only struck out three times. And, like last night, he faces another pitcher that’s not a big bat missser. Trout will enjoy the platoon advantage, too.

Southpaw Matthew Liberatore gets the ball for the St. Louis Cardinals. The former first-round pick has a career 18.9 K% and 4.99 ERA. 

Liberatore kept runs off the board in spring training but struggled to amass strikeouts. I like Trout’s chances to put the ball in play. At these odds, I’ll keep betting him on this market.

Tatis over 1.5 total bases (+108): The San Diego Padres stud enjoys a plus matchup tonight: Logan Allen of the Cleveland Guardians.

Allen was demolished by right-handed bats last season, and San Diego’s leadoff man is one of the best.

  • Righties slashed .306/.377/.574 against Allen in 2024.
  • 18 of his 22 homers were surrendered to RHBs.

While not as extreme, Allen had pronounced lefty/righty splits in his rookie 2023 season, too.

Allen entered last season with promise and is coming off a good spring. But plus money on this prop for a superstar hitter is excellent value to me.

Tatis has topped this in four of five games and enters Tuesday hitting .450 with a 1.150 OPS. He’s struck once in 22 plate appearances.
