The Mariners have won the first two games of their series at T-Mobile Park against the Astros. They managed to do so on Saturday, despite Houston racking up 17 hits to their own seven. The Mariners continue their apparent dominance over the Astros, having won the last five games as the betting favorites. A series usually decided by pitching has instead been decided by hitting. Sunday's pitching matchup will feature Mike Burrows for the Astros and George Kirby for Seattle.

Saturday saw three home runs, one by catcher Raleigh, his second of the season, and Julio Rodríguez finally hitting his first of the season, a towering 426-foot blast to center field. For Houston, Álvarez homered, continuing his dominant run, hitting his sixth of the young season and driving in 14 runs.

It's incredible that the Astros stranded 30 runners on base last night, but that could suggest we'll have another high-scoring game on Sunday.

Our Seattle Mariners vs Houston Astros Prediction

The Astros have won only 1 of their 8 road games this season, but that hasn't been due to their offense but rather their lackluster pitching.

After a few lackluster series at the plate, the Mariners have undoubtedly had some of their most productive series, with Arozarena hitting a key home run in this game. So, betting on it over again seems like the right move.

Our prediction for Mariners vs Astros is: Over 7.5.
