Houston Astros Preview
The Astros lost 8-7 to Seattle in their most recent game and have now dropped six straight, including the first two games of this series. Houston has produced enough offense to stay competitive, but the inability to limit runs has defined this losing streak.
Houston is hitting .281 with a .377 on-base percentage and .462 slugging percentage, making it one of the more productive offenses early in the season. Yordan Alvarez leads the team with a .360 average, six home runs, and 14 RBI, while Jose Altuve and Cam Smith are both hitting over .300. The lineup has consistently created scoring chances and has not been the issue.
The concern is pitching. Houston has a 6.47 ERA and 1.68 WHIP, allowing a .265 opponent average and issuing 87 walks. That level of baserunners has made it difficult to hold leads or keep games within reach, even when the offense performs well.

Seattle Mariners Preview
The Mariners are coming off an 8-7 win over Houston and have taken the first two games of this series. Seattle has now won two straight after a three-game losing streak and has been more effective at home, where they are 5-4 this season.
Seattle is hitting .193 with a .302 on-base percentage and .323 slugging percentage, showing ongoing struggles at the plate. Cole Young leads the team with a .269 average, while Luke Raley has three home runs, and Cal Raleigh leads with 10 RBI. The offense has not been consistent, but it has done enough in key moments during this series.
Pitching has been the strength. The Mariners have a 3.14 ERA and 1.07 WHIP, allowing a .229 opponent average while striking out 134 and walking just 34. That ability to limit baserunners and control innings has allowed Seattle to stay competitive despite lower offensive production.
