Best MLB Prop Bets Today May 15

Thursday is one of the more challenging days for MLB props that we’ve had this season. There are just six games on the schedule, so our options are somewhat limited. However, we’ve been able to take a deep dive into each game to find the best prop bets.

Best MLB Prop Bets Today: White Sox vs. Reds (12:40 PM, EST)

Nick Martinez to Record Win

Martinez has just one win this season in eight starts. In fact, the Reds have only won once in those eight starts. However, he’s not been as bad as those stats might indicate, especially lately. Over his last four starts, Martinez has lowered his ERA from 6.00 to 4.23, so he’s found a groove. The Reds have scored just eight total runs in those four games, so Martinez isn’t getting enough run support. That has a chance to change on Thursday, as the Reds try to avoid getting swept by the lowly White Sox.

Even if the Reds have struggled lately, it makes no sense for them to get swept at home by a team that’s only 5-17 on the road this season. Martinez has pitched six full innings in three straight starts, so he should do his job and put himself in a position to get the win.

Best MLB Prop Bets Today: Astros vs. Rangers (8:05 PM, EST)

Hunter Brown Under 4.5 Hits Allowed

Brown has been the star of Houston’s rotation this season. With a 1.48 ERA, he ranks fourth in the big leagues in that category, while being tied with he most wins with six. More importantly, he’s allowed four hits or fewer in six of his eight starts. Even in two starts in which he gave up three runs, Brown kept the opposing lineup to just four hits.

While the Rangers have won five in a row, they’ve beaten up on the Rockies this week. Facing Brown will be a much stiffer challenge for them.

Marcus Semien Over 0.5 Hits

Admittedly, we’re being a little contradictory with this pick. While Brown has given up a limited number of hits this season, Semien has owned him in the past. Semien is 12 for 19 (.632) in his career against Brown. That is not a small sample size, so there is no doubt this is a favorable matchup for Semien. Of course, the 34-year-old is having a dreadful season, batting just .179.

However, he has a hit in four of his last five games, so there are some signs of life. Also, given his horrible season, Semien has decent odds to get one measly hit, which he should be able to do given his track record against Brown.

Christian Walker Over 1.5 Strikeouts

Walker faces a nightmare scenario on Thursday, with the Astros going up against Jacob deGrom. Walker is 0 for 7 with three strikeouts in his career against deGrom, who has tallied at least six strikeouts in four of his last five starts. Meanwhile, Walker is batting just .208 and has struck out multiple times in four of his last five games.

He went 0 for 12 with seven strikeouts in a three-game series against the Royals this week. Against deGrom, Walker’s struggles are likely to continue, which is why we’ll take the plus-odds on him striking out multiple times again.

Best MLB Prop Bets Today: Athletics vs. Dodgers (10:10 PM, EST)

Freddie Freeman Over 1.5 Total Bases

Freeman has become a frequent target for us, and he’s rarely let us down, so we’re happy to go back to him on Thursday. Despite going just 1 for 7 over the first two games of this series against the A’s, the 35-year-old is batting .362 on the season. Dating back to April, Freeman has collected multiple bases in nine of his last 18 games, which is why we’re getting such good odds on this bet. While Freeman has just two career at-bats against starter Osvaldo Bido, the A’s starter has gotten beat up in his last couple of starts.

We’re betting on the Dodgers having some success against him on Thursday, with Freeman being a big part of that.
