The Astros are coming into this game with a 24-30 record this season and they have not been trending to the over in their recent games. They have seen 7 runs total or less in their last 3 straight as well as 4 of their last 5 games, but their offense has not been awful in these as they have scored at least 5 runs in 2 of their last 4 games. They are going up against a Mariners team that is 29-26 this season and has not been trending to the over in their recent games either. They have also seen 7 runs or less in 4 of their last 5 games, but their offense has not been bad either as they scored 9 runs in their last game prior to this series starting. Luis Castillo is starting for the Mariners in this game and he is 4-6 with a 3.31 ERA this season. He has not been giving up many runs in his starts, but he has not been keeping them off the board either. He has consistently allowed at least 2 earned runs in each of his last 4 starts as well as 5 of his last 6, and he has not been pitching that well recently as he has allowed at least 7 hits in 2 of his last 3 starts while striking out just 5 batters in his last 2 starts combined. He has not faced the Astros this season and this is not a team he has pitched well against as he faced them 3 times last season and allowed at least 4 earned runs in 2 of those 3 starts against the Astros, those 2 starts being the 2 starts he got at home as well. Hunter Brown is starting for the Astros here and he is 1-5 with a 7.06 ERA this season. He has not been great this season as he has allowed at least 2 earned runs in 8 of his last 9 starts. He has also been worse on the road as he has allowed at least 3 earned runs in 3 of his 4 road starts this season, allowing at least 5 earned runs in 2 of those as well. He has also struggled against the Mariners as he faced them twice last season and allowed at least 5 earned runs in each of his starts against them, and he also allowed 2 earned runs against them earlier this season in a start that was at home where he has pitched better this season. Brown is going to give up runs on the road here like he has been doing all season and Castillo is also going to give up runs as he has not been shutting teams out and the Astros are a team he has struggled against a lot over the last 2 years. This total is too low for a game where both starters have not pitched that well this season and have struggled against their opponent in recent starts. Between these two sides, there will be enough runs in this game to push it over the total.
