Caesars Sportsbook promo code for MLB, WNBA and more on July 31

With executives working the phones ahead of the 6 p.m. ET trade deadline, just six MLB teams are in action on Thursday, July 31, but four of those six squads have legit postseason aspirations. The Yankees host the Rays, who have struggled of late and are under .500; the Braves visit the Reds and the Mariners host the Rangers in a pivotal matchup in both the AL West and AL Wild Card races. Thursday's also a lighter day for the WNBA as the Valkyries visit the Mystics, and the final PGA Tour regular season event kicked off this morning with the Wyndham Championship.

After entering 2025 with high expectations, the Braves have fallen flat on their face this year as one of the worst teams in baseball. The same can't be said about the upstart Reds, who are three games behind the Padres for the third and final NL Wild Card spot. Veteran righty Carlos Carrasco (2-2, 5.91 ERA) makes his first start for Atlanta, while Cincinnati starts lefty Andrew Abbott (8-1, 2.09 ERA). Abbott has been stellar all year long for Cincy and is coming off three straight quality starts, while Carrasco, who was most recently with the Yankees, is making his first MLB appearance since May 4. The SportsLine Projection Model, which simulates every MLB game 10,000 times, likes Under 9.5 as its top play for this game, as the Under hits in 58.8% of simulations.

The Rangers head to Seattle to face the Mariners in a series that has massive playoff implications. The Mariners have been busy at the deadline, acquiring Josh Naylor and Eugenio Suarez in two trades with Arizona to bolster the lineup. The Rangers have been one of baseball's best teams in recent weeks to get back into the playoff picture. These two AL West rivals enter the day tied for the third and final AL Wild Card spot, as they're both 57-52. George Kirby (5-5, 4.50 ERA) starts for the Mariners, and Kumar Rocker (4-4, 5.73 ERA) goes for Texas. Kirby allowed two runs in six innings in his last start against the Angels, and Rocker allowed three runs in four innings against the Braves in his most recent start. The model is backing the Mariners to win at home at -174 on the money line. Seattle wins in 60% of simulations.

The Mystics host the Valkyries in Thursday's lone WNBA contest. Washington is 13-13, fourth in the Eastern Conference, and Golden State is 12-13 and fifth in the Western Conference in its first season. WNBA expert Max Meyer has logged his WNBA best bets for Thursday's game, and he has a same-game parlay with two Brittany Sykes props.
