Mariners at Giants picks and predictions
Prediction
Mariners 5 Giants 4
Moneyline
BET MARINERS (+115).
The Giants are just 11-15 as a home favorite the 4th-worst mark in the league and one of only 6 teams to have a sub-.500 win rate in that scenario. Seattle is 10-13 as a road underdog but just won 2 of 3 games against the Rays who have the best record in MLB.
Webb struggled in his last start and the Giants haven’t been great with him on the mound the opposite of the Mariners with Woo.
Run line/Against the spread
PASS.
I don’t see much value here either way. I don’t think the Giants -1.5 (+150) come out on top by multiple runs and I prefer the plus-money moneyline value with the visitors instead of the expensive price tag to get insurance on Seattle +1.5 (-185).
Over/Under
The Mariners have gone Over the total in their last 4 games against an RHP and are 4-0 to the Over in their last 4 games after a victory. Seattle is 42-39-1 O/U this season and 5-1 O/U in its last 6 games.
The Giants cashed the Over in their last game against the Mets and have scored 4 or more runs in 2 of their last 3 outings. Put it all together and take the OVER 7.5 (-105).
