The Picks

  • C.J. Alexander Under 0.5 Hits (+112)
  • Taylor Walls Under 0.5 Hits (+105) 
  • Mariners ML (-108)

Athletics vs. Toronto Blue Jays

Thursday, May 29, 2025 – 7:07 PM EDT at Rogers Centre

The AI Model thinks C.J. Alexander will only add .535 hits tonight for the Athletics. However, Alexander’s under .5 hits are currently at an underdog price of +112. There’s some value on this plus-money prop!

C.J. Alexander Needs Time!

The Athletics will give C.J. Alexander the start at third base tonight. He hasn’t been up in the league for very long. However, he’s hit a .000 ISO and wOBA of .297 with no walks against righties since getting the call.

Alexander has hit no balls with the barrel and has added just 20% of hard contact.

Tonight, he’ll take on Jose Berrios of the Blue Jays. Ultimately, Berrios has limited lefties to 21.2% of fly balls and has earned 43.3% of ground balls against lefties this season. His strikeout rate is low, and his walk rate is high. Walking Alexander wouldn’t be an issue. We’re looking for Alexander not to earn a hit.

So far this season, he’s added a .222 average in nine at-bats. He’s got a career .176 average in 17 at-bats. He also doesn’t even have a home run or an RBI. He’s also never had a stolen base and has a career OPS of .352.

Alexander has potential in the MLB, but it will undoubtedly take him some time. A matchup against a veteran righty isn’t ideal.

Fade Alexander tonight. Let’s grab his under in the hits category for plus-money.

Tampa Bay Rays vs. Houston Astros

Thursday, May 29, 2025 – 8:10 PM EDT at Daikin Park

Our AI Model thinks Taylor Walls will only add .455 hits in tonight’s game for the Rays. Meanwhile, his hits prop is at .5, with the under at +105. The AI Model believes there’s value on fading Walls tonight.

Walls Might Walk, But That Doesn’t Matter

Taylor Walls and the Tampa Bay Rays will battle Ryan Gusto of the Houston Astros. Gusto hasn’t been great recently, but he’s held his first 77 lefties to a BABIP of .302, which isn’t all that bad.

Walls, a switch-hitter, has added a .030 ISO and wOBA of .257 against his last 41 righties. He’s walked 17.1% of the time and is patient. However, he’s also hit 30.8% of hard contact, a 0% barrel percentage, and a .231 BABIP against righties over the last 30 days.

Walls hasn’t produced against righties very much over the last 30  days. Let’s fade him at +105 MLB odds.

MLB Pick: Taylor Walls Under 0.5 Hits (+105) at Bet365


Washington Nationals vs. Seattle Mariners

Thursday, May 29, 2025 – 9:40 PM EDT at T-Mobile Park

The AI Model suggests the Seattle Mariners will earn a 4-3.1 win over the Nationals. The Mariners are slight underdogs at -108, but are expected to win by a solid margin using the AI Model. Let’s bet on the Mariners tonight.

MacKenzie Gore Is Only Good For Strikeouts!

The Washington Nationals will pitch MacKenzie Gore for tonight’s game against the Mariners. Gore has a high strikeout rate, but he’s also allowed a .184 ISO and wOBA of .336 to his last 115 batters.

The Mariners aren’t the most consistent offense against lefties. However, Julio Rodriguez, Cal Raleigh, and Randy Arozarena have done some damage. Those three can lead the charge against Gore.

Meanwhile, the Nationals’ offense has hit a .124 ISO and wOBA of .288 against righties over the last 30 days. They’ll take on Emerson Hancock, who has limited his last 127 batters to 7.1% of walks and 45.9% of ground balls. Hancock has a better overall matchup, so grab the Mariners at -108.
