Zimmermann roughed up by Cardinals in defeat

Righty allows eight early runs; Owings, Walters go deep in seven-run ninth

VIERA, Fla. -- Right-hander Jordan Zimmermann had an outing he would like to forget as the Cardinals outslugged the Nationals, 16-10, at Space Coast Stadium on Friday afternoon. Washington is on a three-game losing streak, while the Cardinals have won three in a row.

Zimmermann pitched three innings and allowed eight runs on nine hits. He threw 61 pitches, 39 for strikes. St. Louis went to work on Zimmermann in the second, scoring two runs. David Freese scored on a groundout by Rob Johnson, while Shane Robinson scored on a single by Ronny Cedeno to make it 2-0.

The Cardinals sent 10 hitters to the plate in the third and scored six runs off Zimmermann. Johnson and Greg Garcia highlighted the scoring with two-run hits.

The Nationals scored their first two runs off Cardinals right-hander Shelby Miller in the third on Bryce Harper's two-run triple, scoring Wilson Ramos and Chad Tracy.

Nationals reliever Nathan Karns was on the mound when St. Louis scored seven runs in the fifth. Shane Robinson highlighted the scoring with a grand slam to make it 15-2. Only one of the seven runs was earned because of an error by Anthony Rendon.

In the sixth, Ryan Zimmerman doubled in Cory Brown for the Nats' third run.

The Cardinals scored their 16th run in the eighth off left-hander Patrick McCoy. Cody Stanley crossed the plate on a single by J.R. Towles.

In the ninth, Washington plated seven runs. Zach Walters hit a two-run shot, Micah Owings ripped a solo homer, Matt Skole added a two-run single, Chris Marrero collected an RBI double and Steve Lombardozzi hit an RBI single.

Up next: The Nationals return to Space Coast Stadium to host the Marlins on Saturday at 1:05 p.m. ET. Right-hander Chris Young will replace Ross Detwiler in the rotation and make his first start for the big league club. On Monday, Young allowed two unearned runs in two innings in a Minor League intrasquad game at Space Coast Stadium. Young struck out one and walked none. He threw 41 pitches, 26 for strikes.
