Houston Astros vs. Boston Red Sox preview
The Red Sox roll into Houston looking to prove their 65-54 record is no fluke, but they'll face a rejuvenated Astros squad that's grinding out wins at home behind solid pitching.
Boston's offense has been clicking at fifth-best in the league with 5.0 runs per game, though they'll have their work cut out against Houston's stingy staff that ranks fifth in runs allowed at just 3.94 per nine innings.
Dustin May takes the ball for Boston with decent career numbers, but Spencer Arrighetti has been inconsistent for the Astros with a 4.78 ERA that could give the visiting bats some hope.
Houston's bullpen advantage is real here, posting a league-best 73.9% save rate compared to Boston's shaky 59.3% mark that's cost them games down the stretch.
The Red Sox have struggled defensively all season, ranking 29th in fielding percentage, which could be costly against an Astros team that knows how to capitalize on mistakes at home.
This Tuesday night clash at Daikin Park should be a proper test for both clubs, with Houston's pitching depth likely to be the difference maker in what projects as a tight, low-scoring affair.
