Best MLB Player Props Today

Christian Walker to Record 2+ Total Bases (+120)

Tobias Myers is someone we can feel good about picking on, and that has me looking at Houston Astros player props. Christian Walker to record at least two bases is my favorite of the bunch.

Myers was decent as a rookie (3.99 SIERA), but he's really struggled so far in 2025. His MLB sample is only seven innings, but in that span, he's got a 6.38 SIERA, 20.6% walk rate and 7.0% swinging-strike rate. Obviously, we can't put too much stock into seven innings, but he was also bad in 13 1/3 Triple-A innings earlier this spring, mustering a lowly 14.5% strikeout rate while allowing a 48.8% fly-ball rate.

Giving up a lot of fly-balls is something Myers did in 2024, too, with the righty permitting a 40.6% fly-ball rate.

Walker is starting to heat up. Over his last 45 plate appearances, he's logged a .357 wOBA with a pair of jacks. Myers' fly-ball ways should be a good matchup for Walker, and I like the Astros' slugger to rack up two-plus bases.

Brandon Nimmo to Record an RBI (+140)

The New York Mets are in a smash spot today against Ryne Nelson, and Brandon Nimmo can take advantage.

Nelson, exclusively a reliever so far in 2025, is being forced into action because the Arizona Diamondbacks are giving Corbin Burnes a little time off to rest an ailing shoulder. Prior to this season, Nelson was primarily a starter in his career, and it didn't go all that well -- hence his move to the 'pen. Across 2023 and 2024 (294 2/3 frames), Nelson pitched to a 4.64 SIERA and 17.8% K rate.

The Mets are expected to have success offensively as they're listed at -120 to go over 4.5 runs. Nimmo will likely be slotted fourth or fifth in the lineup, putting him behind the likes of Francisco Lindor, Juan Soto and Pete Alonso. That's a pretty great spot for RBI chances.

Miles Mikolas Under 17.5 Outs Recorded (-118)

While it's tough on the stomach to back the Pittsburgh Pirates' offense, I'm doing so today via this prop.

Let's get this out of the way: the Pirates are one of the worst offenses in the league, ranking 26th in wOBA. But Miles Mikolas isn't very good, either, and six innings is a high bar in today's game.

Mikolas has fallen off a cliff so far in 2025, recording a 5.02 SIERA and 13.4% K rate. Despite a 43.0% fly-ball rate, Mikolas hasn't allowed a dinger due to a lucky 0.0% homer-to-fly-ball rate, but the long-balls are coming.

Mikolas has notched 16 or fewer outs in five of his six outings this campaign. He's completed six innings just once, and he's thrown more than 82 pitches only once. Even in a nice matchup, Mikolas should have a tough time getting 18 outs.
