Rockies' baserunning gaffes add to woes

DENVER -- With minimal scoring chances, two baserunning errors added to the Rockies' woes in their 4-2 loss to the Phillies on Wednesday night at Coors Field.

In the fourth, Wilin Rosario rocketed a two-out single to left with Carlos Gonzalez on first, seemingly setting the Rockies up with a prime opportunity to further chisel into the Phillies' 4-1 advantage. Left fielder Ben Revere fired his relay throw in to third as Rosario tried to snag an extra base -- but shortstop Freddy Galvis cut the ball off and whipped a short throw to second.

Rosario didn't stand a chance.

"I think he saw the ball going to third and tried to make an aggressive play there," Rockies manager Walt Weiss said. "The shortstop did a nice job. He never hesitated and wheeled around and threw it to second immediately. I think Wilin thought that ball was going to be relayed to third."

Had Rosario stayed at first, recent callup Ben Paulsen would've batted with men on the corners. As a result, Paulsen led off the fifth -- and like Rosario, he too singled to left. But just one batter later, Paulsen also displayed a lack of baserunning awareness.

The call was a hit-and-run. Nick Hundley's connection with a Severino Gonzalez fastball appeared sufficient as a line drive was crushed to center.

Except center fielder Odubel Herrera left his feet and snagged Hundley's loud out. Paulsen was halfway to third before he peeked. It was easy double play.

"It was a bad read by me," Pauslen said. "It was one of those where I was too aggressive, and next time, if it goes through, I'll be standing on third -- or back on first.

"I thought Nick crushed that ball, and I read it off the bat right away as a double and maybe scoring. Next time, I just can't be so aggressive."

From there, the Rockies mustered just one runner into scoring position.

"You can't make outs on the bases," Weiss said.

Worth noting:

• Colorado reliever Brooks Brown (right-shoulder inflammation) will likely make another rehab appearance with Triple-A Albuquerque on Thursday in hopes of returning some time during the Rockies' four-game weekend series vs. San Francisco.

If the rehab outing goes without any setbacks, Weiss said Brown still wouldn't be activated from the disabled list until potentially Saturday -- with Friday serving as a rest day.

"With Brooks, we want him to go down and possibly throw one-plus [innings]," Weiss said. "Doesn't have to be two innings, but he does that often with us. We want to make sure he can do that and bounce back and be fine."
