The Boston Red Sox (65-54) head to Houston's Daikin Park on Wednesday night looking to salvage the series finale against the Astros (66-52) in what's become a reunion tour featuring Alex Bregman's return to Houston and Carlos Correa back in an Astros uniform.
Both teams are locked in tight playoff races with Boston clinging to the second Wild Card spot despite road struggles (26-33 away from home) while Houston battles for AL West supremacy with elite offensive numbers (.259 team average, 133 homers) despite key injuries.
The pitching matchup features Walker Buehler (7-6, 5.40 ERA) trying to build on his recent success against this same Astros lineup versus Hunter Brown (9-5, 2.51 ERA), who dominated Boston in their last meeting but still took the loss in extras.

Houston Astros vs. Boston Red Sox preview
The Red Sox arrive in Houston carrying momentum from their recent series win over the Astros at Fenway, where Walker Buehler outdueled Hunter Brown just 11 days ago in a 7-3 Boston victory.
Both teams are locked in playoff races, with Houston clinging to the AL West lead while Boston holds down the second Wild Card spot despite their pedestrian 26-33 road record.
The storylines write themselves with Alex Bregman now wearing a Red Sox uniform returning to his former home, while Carlos Correa has made his way back to Houston to help fill the void left by Isaac Paredes' season-ending injury.
Buehler has been shaky away from Fenway with a 6.52 road ERA, but the Red Sox have won his last three starts, suggesting he's finding his rhythm when it matters most.
Brown has been Houston's most reliable starter with a stellar 2.51 ERA and dominant 0.98 WHIP, though he'll be looking for revenge after Boston tagged him for seven runs in that August 2nd matchup.
Both bullpens rank among the league's elite, setting up what could be a late-game chess match between two clubs that have combined for at least eight runs in seven straight contests.
