Astros at Mariners picks and predictions
Prediction
Astros 4, Mariners 3
Moneyline
BET ASTROS (+115).
Houston is 5-1 in its last 6 road games vs. teams with a losing record and should bounce back after choking away a 3-run lead in the 8th inning Saturday. Seattle has not played up to the level of its competition lately and is 1-5 in its last 6 home games vs. teams with a winning record. The Astros have been good at closing out series and are 41-11 in their last 52 during game 3 of a series.
Run line/Against the spread
PASS.
Houston +1.5 (-175) should hit, but there is no need to pay the higher price on the run line when the Astros moneyline should hit. Bet Houston moneyline and/or the total instead.

Over/Under
BET UNDER 8.5 (-115).
The Under is 4-0-1 in Houston’s last 5 during game 3 of a series and 4-1-1 in its last 6 after a loss.
These teams tend to play low-scoring games vs. each other in Seattle, with the Under hitting in 6 of the last 8 meetings, and Sunday’s matchup should stay under the total once again as Seattle’s offense comes back down to Earth after plating 7 runs in the 8th inning Saturday.
