The New York Mets opened this series with a 3-1 win, and I think Game Tuesday night will be another low-scoring affair.

Arizona right-hander Zac Gallen (3-4, 2.50 ERA) is coming off the best start of his rookie season as he allowed just one hit over seven shutout innings in a 4-1 victory over the Padres last time out. He has posted a 2.25 ERA in six starts since coming over from Miami with five games going under the total and one push during that stretch.

As for Mets' starter Zack Wheeler (10-7, 4.33 ERA), the 29-year-old right-hander has posted a 3.42 ERA in eight starts since coming off the injured list and he held the Nats to one run over five innings last time out. Wheeler is 3-1 with a 2.82 ERA in six career starts against the Diamondbacks.

Under is 5-1 in the last 6 meetings at Citi Field. Under is 4-1-1 in the last 6 meetings overall.

8* play on UNDER.
