NEW YORK (Interstat) — The New York Mets and Colorado Rockies conclude a three-game series Sunday at Citi Field, with a forecast of 46-degree rain complicating an already challenging season for both last-place clubs.

First pitch is scheduled for the afternoon, though the conditions could lead to delays. The Rockies (11-16) took the series opener Friday 4-3 and played a scoreless tie Saturday that was suspended.

Colorado sends left-hander Jose Quintana (0-2, 5.40 ERA) to the mound. The veteran has struggled to find consistency, having allowed multiple runs in three of his five starts. He will face a Mets lineup that ranks near the bottom of the National League in runs scored.

New York (9-17) counters with right-hander Freddy Peralta, who has been unlucky despite solid peripherals. Peralta pitched 5 2/3 innings of two-run ball Friday against these same Rockies, striking out eight but taking the loss. He has a 2.95 ERA over his last four outings.

A key player to watch for Colorado is reliever Michael Lorenzen, who has been effective in multiple roles. Lorenzen threw seven innings of one-run ball Friday in a spot start against the Mets, and he has a 2.92 ERA over his last seven appearances.

For New York, right fielder Brett Baty went 2 for 4 with two RBIs in Friday’s loss. The Mets have dropped four of five and scored three runs or fewer in three of those games.

The game total is set at 7.5 runs, with New York installed as a 1.5-run favorite. The Rockies have won five of their last seven overall and have been competitive on the road.

Colorado’s schedule includes a trip to Cincinnati beginning Tuesday, while New York returns home to face Washington. These two teams will meet again in Colorado from May 4-6.

The series finale gives both teams an opportunity to gain traction, though the cold and wet forecast may test both pitching staffs and favor the visitors, who won the first meeting and carry momentum into the rubber match.
