INSIDE PITCH

DENVER -- Ryan Zimmerman had an MRI on his strained right hamstring Wednesday morning, and the news was not good: The Nationals placed the third baseman on the 15-day disabled list.

"It's a pretty substantial strain of the hamstring," manager Matt Williams said after the Nationals' 6-4 loss to the Colorado Rockies. "It's going to be a couple weeks, at least."

Zimmerman was injured in the fifth inning Tuesday night, running hard to first base to avoid hitting into a double play. He grabbed his hamstring just as he neared the base and then stumbled over the bag.

"It's hard to say anything on a long-term outlook," Zimmerman said. "I'm sore today, just like we thought I would be. We don't really have any timetable or anything like that, other than it's a pretty decent strain, and I'm pretty sore today."

This is the second time this season that Zimmerman has gone on the disabled list. He missed 44 games with a fractured right thumb before returning June 3. In July, Zimmerman is hitting .362 (21-for-58) with a .418 on-base percentage and a .569 slugging percentage.

"It's tough, but those are things that happen," he said. "There's nothing you can really do about it. There's no reason to pout or feel sorry for yourself. I'm going to be here for these guys. We're playing good baseball. I think we'll continue to do that until I get back. And hopefully I'll get back sooner rather than later."

With Zimmerman in the starting lineup, the Nationals are 33-19 and averaging 4.9 runs per game. Without him, they are 22-25 and averaging 3.5 runs.

After Wednesday's game, Zimmerman flew with the Nationals to Cincinnati, where they play Friday. Williams said Zimmerman could be more comfortable on the team's charter than he would be on a commercial flight.

"He'll get back from there in the next day or so and start getting some work done on it with the therapists at home," Williams said.

To replace Zimmerman on the roster, the Nationals recalled infielder Zach Walters from Syracuse of the Triple-A International League.

NOTES, QUOTES

RECORD: 55-44

STREAK: Lost one

NEXT: Friday -- Nationals (RHP Tanner Roark, 9-6, 2.91 ERA) at Reds (RHP Alfredo Simon, 12-4, 2.74 ERA)

PLAYER NOTES:

--RF Jayson Werth did not start, but he pinch-hit in the seventh and went 1-for-2 with one RBI. Manager Matt Williams said Werth has had a little "barky" knee coming out of the All-Star break, adding the knee was hurting him in a series against Milwaukee before the Nationals came to Colorado. Werth was sore after a busy Tuesday night in which he ran down a couple of hits in the right-field corner.

--3B Ryan Zimmerman (right hamstring strain) was placed on the 15-day disabled list. He was injured in the fifth inning Tuesday night, running hard to first base and avoiding hitting into a double play. He grabbed his hamstring just as he neared the base and then stumbled over the bag. Zimmerman underwent an MRI on Wednesday morning that revealed what manager Matt Williams called "a pretty substantial" strain.

--INF Zach Walters was recalled from Triple-A Syracuse after 3B Ryan Zimmerman (right hamstring strain) was placed on the 15-day disabled list. Walters began his second stint this season with the Nationals as a pinch hitter and singled in the ninth and scored. In his past 10 games with Syracuse, Walters hit .475 (19-for-40) with four homers and 10 RBIs and tallied a .523 on-base percentage and .875 slugging percentage. He appeared in 27 games, starting twice, for the Nationals from April 13 to May 24 and hit .182 (6-for-33) with three home runs and four RBIs.

--CF Denard Span went 4-for-5. Three of the left-handed-hitting Span's hits came off LHP Jorge De La Rosa, matching Span's career high for hits against a left-hander. He also did it Sept. 14, 2013, against Philadelphia. It was Span's ninth game of three or more hits this season and second since the All-Star break. The other was on Friday against Milwaukee.
