The New York Mets have won four in a row and will go for a series sweep of the defending NL East champion Washington Nationals Sunday night. There's definitely some value on Mets as an underdog here, and I think they'll cover the runline in a low-scoring contest.

The Mets hand the ball to Matt Harvey (0-0, 0.00 ERA) who allowed just one hit in five scoreless innings against the Philadelphia Phillies in his season debut. Under is 6-2-2 in Nationals last 10 home games vs. a right-handed starter and Harvey is 1-3 with a 3.86 ERA in six career starts here at Nationals Park.

The Nats turn to Tanner Roark (1-0, 1.29 ERA) who is is 7-2 with a 2.76 ERA in 17 games (11 starts) against the Mets and went seven innings, allowing a run, four hits and a walk against the Atlanta Braves on Monday night. Under is 6-1 in Roark's last seven home starts and 9-1 in his last 10 starts following a Quality Start in his last appearance.
