Rafael Montero allowed four runs on 10 hits in six and 2/3 innings in the Mets' 5-4 loss to the Rockies on Thursday.
The Rockies scored two runs in the third inning behind back-to-back RBI singles by DJ LeMahieu and Nolan Arenado. Montero later allowed solo home runs in the fifth and sixth innings.
Offensively, Montero picked up his first career RBI when he drove in Amed Rosario in the fifth inning. He notched his first big league hit last month in a game against the Athetics at Citi Field.
Montero departed in a tie game in the seventh inning, marking his second straight no-decision. Hansel Robles went on to earn the loss after issuing a bases-loaded walk in the ninth inning.
Montero, who has made eight starts for the Mets this season, has not won a game since June 25. He is 1-7 with a 5.78 ERA in 22 games for the Mets this season.
