The Colorado Rockies (15-27) have fallen to 4-16 in the month of May after losing to the Miami Marlins (24-19) last night 7-6 in Miami. The Rockies trailed 7-4 in the eighth inning before mounting a rally that fell one run short. The two team wrap up the series tonight at 5:10 MT in Marlins Park (TV: Root Sports).

For the second time in as many nights, the Rockies jumped out to an early first-inning lead, which proved to be short-lived.

Colorado pushed three across in the first thanks to a pair of RBI singles from Helton and Cuddyer, who finished the game 3-for-3 with two doubles and a walk, and a sacrifice fly from Rosario.

That lead quickly evaporated with righty Juan Nicasio struggling on the mound. Nicasio said he felt tired during the first three innings, but had no lingering effects from the line drive he took off the hip in his last start.

“I don’t know what happened with me,” Nicasio said. “In the first and second innings I was feeling down, I can’t throw my fastball hard, but in the fifth inning I was feeling strong — in the fourth inning, too.”

The Rockies are now owners of the worst record in the National League.

“It’s extremely frustrating for all of us,” Rockies manager Jim Tracy said. “It’s actually very painful to sit here, and knowing the kind of effort they’re putting forth, and to be thwarted and frustrated night after night. It’s painful as hell. … That gets tough to take.”
