Sure, on paper, it looks like these two teams will have trouble breaking the six-run barrier with a pitching matchup of lefty Madison Bumgarner versus righty Noah Syndergaard.

But there are a number of factors that point to this low total going over. It's not too much to ask either of these two teams to put up three runs apiece, which would be enough to push this above the total.

The Giants have scored at least three runs in seven of their last eight games. They've faced some excellent starters, too, during this span, including Clayton Kershaw, Johnny Cueto and Rich Hill. San Francisco has gone over six of the past seven times it has faced a righty starter. The Giants square off against Syndergaard without a weak hitter in the lineup as Bumgarner is one of the best-hitting pitchers in baseball.

The Mets were able to overcome devastating injuries to three of their key young pitchers by playing long-ball smacking a franchise-record 218 homers. That was the second-most in the National League. Bumgarner wasn't that sharp either down the stretch surrendering four or more runs in four of his last nine starts.The over cashed in seven of his last 10 starts. The Mets also have gone above the total seven of the past eight times they've faced a southpaw starter. The over has cashed five of the last six times Bumgarner has opposed the Mets.

San Francisco also has a shaky bullpen. It blew five ninth-inning leads in September.
