Best MLB Prop Bets Today: Tons of Value Available with Monday’s Prop Picks

Best NBA Prop Bets Today May 12

Last week was easily our most successful of the season. We started strong and finished strong, giving us high hopes for another good week. On Monday, we’re going to be a little aggressive, targeting several MLB props with plus odds that we think offer great value.

Best MLB Prop Bets Today: Pirates vs. Mets (7:10 PM, EST)

David Peterson to Record Win

Despite pitching well this season, posting a 3.05 ERA, Peterson hasn’t had much luck when it comes to picking up wins. The lefty has just two wins in seven starts, one in late March and another in late April. However, the Mets are 5-2 in games he’s started, so the opportunity is there because Peterson has pitched well enough to win in most of his outings. On Monday, he’ll face a Pittsburgh team that has just three wins in its last 14 games, giving the Mets a good chance to win. Also, despite winning a series against the Braves over the weekend, the Pirates have scored just 14 total runs over their past eight games. If Peterson can keep performing, he should leave Monday’s game with a lead and a chance to win.

Pete Alonso Over 1.5 Total Bases

The Mets are hoping Alonso will help give Peterson a lead on Monday. With the fourth-highest OPS in the big leagues, Alonso has been one of MLB’s best hitters all season. He and the Mets have to deal with Paul Skenes on Monday, but that’s why this bet has such good odds. While he’s cooled off a little in May, Alonso has six extra-base hits and three multiple-hit games over his last 10 games. He’s also 2 for 3 with a double in his career against Skenes. While that’s not a big sample size, it tells us that Alonso is more than capable of mashing against Pittsburgh’s ace the way he has against every other pitcher this season.

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

Xander Bogaerts Over 1.5 Hits/Runs/RBI

This has become one of our favorite prop bets to target this season. Bogaerts isn’t having a great season, but he hits in the middle of a dangerous San Diego lineup, which gives him plenty of opportunities to score runs or drive them in. He’s also capable of having a multi-hit game, doing so three times in his last seven games. Equally important, Bogaerts has been more productive against left-handed pitching this season. He’s also 3 for 8 with a pair of home runs in his career against Yusei Kikuchi, who starts for the Angels on Monday. That puts Bogaerts in a good position to be productive.

Jorge Soler Under 0.5 Hits

With a .233 average, Soler has become a hitter who’s easy to face. To his credit, Soler has a hit in the last three games that he’s started. But he’s still batting just .200 in May, so that doesn’t sound like a streak that’s going to last very long. He also has a surprisingly tough matchup on Monday against San Diego’s Michael King. Soler is 0 for 11 with four strikeouts in his career against King. In fact, he’s 3 for 50 (.060) in his career against pitchers on San Diego’s roster, giving us low hopes for Soler throughout this series.

Best MLB Prop Bets Today: Diamondbacks vs. Giants (9:45 PM, EST)

Merrill Kelly Under. 5.5 Hits Allowed

The Giants just got swept by the Twins over the weekend. They’ve also been limited to three runs or less in four of their last six games, so Kelly is getting them at a good time. Kelly’s modest 4.09 ERA is a little bit of an illusion because he’s been hard to hit. Before allowing three runs on six hits against the Mets in his last outing, Kelly gave up four hits or fewer in five consecutive starts. In eight starts, only the Mets and Yankees have managed more than four hits against him. On Monday, Kelly only has to keep the Giants to five hits or fewer, which makes this a no-brainer.
