Best MLB prop bets March 29: Bet on big bats Alvarez and Guerrero Jr.

MLB prop bets

Yordan Alvarez’s power is highlighted in Saturday’s MLB prop bets.

The pregame narrative: I’m betting on the slugger to get his first hit of the season in style. I also have picks on Max Muncy and Vladimir Guerrero Jr.

Check out the best MLB prop bets for Saturday, March 29.

MLB prop bets

Best bet: Alvarez over 1.5 total bases (+105)

Alvarez is hitless in two games to start the season but it hasn’t been all that bad.

He has three walks, translating to a .375 OBP, which is above average. Walks don’t help us here but I think this is the perfect spot for Alvarez to break out with the bat.

  • In 13 at-bats against New York Mets starter Griffin Canning, he has seven hits (.539 batting average)
  • That includes one double, two home runs and more walks (3) than strikeouts (2).
  • Canning has a career ERA of 4.78 and is coming off his second-worst season in the majors (5.19 ERA).

The Astro’s top slugger sees Canning well and is in a great spot to have his first great game of the season.

Key stat: In 2024, Yordan Alvarez racked up a career-high 313 total bases. 

Best MLB picks

Muncy 1+ RBI (+165): Muncy’s had a rough start to the season; there’s no denying that. He has one hit in 14 at-bats and is looking for his first RBI.

The good news is that he’ll be in a prime position to be productive tonight.

In three plate appearances against Detroit Tigers starter Reese Olson, Muncy has one single, one walk and one home run.

He batted .256 against right-handed pitching last season, with 41 RBI, per Fan Graphs. That’s much better than his .172 average against lefties.

With Olson on the mound, Muncy should continue hitting in the five-hole behind Shohei Ohtani, Mookie Betts, Freddie Freeman and Teoscar Hernandez.

That’s a premium spot to be in to drive in some runs. I’ll gladly take a shot at this price.

Guerrero Jr. over 1.5 total bases (+100): There’s arguably no better matchup for a hitter on today’s slate.

Guerrero has seen Oriloes’ starter Dean Kremer 30 times, batting .357 with 5 home runs and two doubles.

And I know it’s only two games, but I’m convinced the slugger is in for a great season after his incredible second half of 2024.

He had two walks on opening night, scoring one of the Blue Jays’ two runs. He followed that up with a two-hit performance yesterday with one going for extra bases.
