Giants at Mariners picks and predictions

Prediction

Mariners 3, Giants 2

Moneyline

The MARINERS (-142) are a worth a look in the series finale Sunday, as Woo has been nearly untouchable at home.

Woo has allowed just 6 ER and 3 BB in 35 IP across 6 home starts this season. Seattle has had a lot of trouble with consistency lately, but Woo definitely hasn’t been the problem.

The Giants (+120) aren’t going to go quietly, as Ray has been pretty solid on the road, too. But you have to side with Woo, especially at home.

The Giants +1.5 (-178) will cost you nearly 2 times your potential return if you’d like a little insurance, and you just can’t take the visitors straight up.

That’s way too much risk and not nearly enough reward. If you like San Francisco, just bet it straight up.

AVOID.

UNDER 7 (+100) is worth playing a look with this pitching matchup between Ray and Woo. We should see plenty of donuts from both of these pitchers.

While playing the Under is going against the trends for Seattle, since the Over is 6-1-1 in the past 8 outings, that lone Under is when Woo pitched. In fact, the Under has cashed in each of the past 3 starts by the Seattle right-hander.

For the Giants, the Under has a slight 5-4-1 edge in the past 10 games, but be careful. The Over is 5-1 in the past 6 road outings for San Francisco, including the first 2 games of this series.

You may love betting on sports, but until college football and the NFL seasons officially start, the pickings can get slim. You can fill some of that time and scratch that itch at online casinos and enjoy slots, blackjack, video poker and more.
