Friday trading preview
- Astros to beat Rangers (54%)
- Dodgers to beat Red Sox (55%)
Don't look now, but here come the Astros. Houston has won eight of its last 10 to claw back to .500, which is good enough for second place in the AL West. They're just a half-game behind the Texas Rangers, who come to Houston to open an extremely important three-game series on Friday. Hunter Brown (2-1, 3.45 ERA) gets the ball for the Astros while Nathan Eovaldi (10-8, 4.05) goes for the Rangers. The SportsLine Projection Model, which simulates every game 10,000 times, has Houston winning at a 60% rate. Polymarket has the Astros priced at 54%.
Also surging back into relevance are the Boston Red Sox, who at one point won 15 straight games. They're currently seven for their last 10, but going to Los Angeles to face the Dodgers is no easy task. Boston will be without recent trade acquisition Curtis Meade, as the infielder suffered a fractured wrist just two plate appearances into his Boston tenure. The Sox will start Ranger Suarez (4-3, 3.02) on Friday while Edgardo Henriquez (4-1, 2.79) will serve as an opener for the Dodgers. L.A. wins in 63% of the model's simulations. Polymarket offers the Dodgers at 55%.
