Best MLB Prop Bets for Today: Keeping Things Simple with Saturday’s Prop Bets

Best MLB Prop Bets Today May 31

We’ve been on a roll late in the week, and there’s no reason we can’t keep it going on Saturday. With 15 games on the schedule, we had plenty of options, narrowing it down to our five favorite prop bets for the day. We kept things simple on Saturday, but have high hopes for all of our picks.

Best MLB Prop Bets Today: Tigers vs. Royals (4:10 PM, EST)

Mark Canha Over 0.5 Hits

Canha doesn’t play every day, but he’ll be in the lineup Saturday against lefty Tarik Skubal. That’s where the veteran outfielder has excelled the most this season, hitting .344 against lefties. Canha doesn’t have much power to speak of and often gets taken out of the game if the opposing team goes to a righty in the bullpen.

However, the chances are good that Canha can get one hit before Tarik Skubal leaves the game, especially since Skubal typically pitches deep into games. Canha is 2 for 6 with a home run and three walks in his career against Skubal, so this appears to be a favorable matchup for him.

Best MLB Prop Bets Today: Rockies vs. Mets (4:10 PM, EST)

Antonio Senzatela Over 2.5 ER

This is the first bet everyone should be making on Saturday. Senzatela is 1-9 with a 6.50 ERA on the season and has given up at least four runs in six consecutive starts. He’s obviously a lot worse when pitching at Coors Field, but Senzatela also has a 5.32 ERA on the road. To be fair, the Mets are only averaging a modest 4.3 runs per game over their last eight games despite being 6-2 during that stretch.

But they have more than enough lineup depth to do damage against Senzatela. We were prepared to bet over 3.5 earned runs for Senzatela, so over 2.5 is a no-brainer.

Pete Alonso Over 1.5 Total Bases

With a six-game hitting streak, Alonso is one of the best hitters to target against Senzatela on Saturday. While he only has one multi-hit game in those six games, Alonso has an extra-base hit in four of his last five games. He has 30 extra-base hits in 57 games this season, so there is a good chance he adds to that total, even if he can’t collect multiple hits.

Alonso is 4 for 11 (.364) with a double in his career against Senzatela, giving us every reason to think he will be a big part of the success the Mets are likely to have against Colorado’s starter on Saturday.

Best MLB Prop Bets Today: Giants vs. Marlins (4:10 PM, EST)

Robbie Ray Under 2.5 ER (-150) at bet365 Sportsbook

Even if the line were 1.5 earned runs, we’d still target Ray for this bet. After showing some positive signs offensively earlier this week, the Marlins were back to their old tricks on Friday, scoring no runs on just three hits. Playing a day game after a night game, it could easily be more of the same on Saturday. Meanwhile, Ray has been electric throughout May, pitching to a 1.41 ERA. He’s allowed one run or less in four of his last five starts and two runs or less in six of his last seven starts.

Virtually nobody in Miami’s lineup has faced him before, which only makes things more difficult for the Marlins. Obviously, we wish there was more value, but this feels like a safe bet.

Best MLB Prop Bets Today: Pirates vs. Padres (9:40 PM, EST)

Bailey Falter Under 3.5 Strikeouts

The Padres are the toughest team in baseball to strike out, which is why it’s easy to fade Falter in this spot. To his credit, Falter has a 0.92 ERA across his five starts in May. But those starts haven’t always been accompanied by a lot of strikeouts. He’s failed to go beyond three strikeouts in three of his last four starts and five of his last eight starts.

Even after striking out six Padres across seven innings earlier this month, the San Diego lineup should be better prepared for Falter this time around, keeping his strikeout total low.
