• No relief: For the third time in three days, the Colorado bullpen failed to hold an eighth-inning lead. This time LaTroy Hawkins gave up a solo homer to Josh Phelps to tie the game.
• Unsung heroes: Five Pittsburgh relievers combined for four-plus scoreless innings, allowing just one hit along the way.
• Figure this: The Pirates have now won four straight road games, which is their best road win streak since Aug. 2004.

Pirates 4, Rockies 2 (11 innings)
DENVER (AP) -- For the third straight day, the Colorado Rockies had an eighth inning lead. For the third straight day, their bullpen couldn't hold it.
LaTroy Hawkins gave up a pinch-hit home run to Josh Phelps to tie the game in the eighth, and Brian Fuentes allowed a game-winning single in the 11th by Freddy Sanchez as the Pittsburgh Pirates beat the struggling Rockies 4-2 on Monday night.
It was another frustrating appearance for Fuentes, who went on the DL in early July after blowing saves in four consecutive outings. No longer the closer, Fuentes struggled with command, facing five batters and walking one, hitting another and allowing a single.
"Command was the issue plain and simple for Brian Fuentes," Colorado manager Clint Hurdle said.
Fuentes was gone before the clubhouse doors opened and wasn't available for comment.
The Rockies opened a crucial seven-game homestand against the Pirates and Washington Nationals, two of the worst teams in the National League, and lost for the fifth time in seven games.
"Freddy had a great at-bat in the 11th, something he's done a few times in the past four or five days," Pittsburgh manager Jim Tracy said.
Said Sanchez: "Fuentes has some good stuff. I just wanted to put the ball in play and find a hole and the ball found a hole."
LaRoche went 3-for-5 with a pair of doubles. Josh Phelps hit a pinch-hit home run for Pittsburgh.
Tulowitzki defended himself for being thrown out trying to steal second base after singling to open the 10th. Matt Holliday struck out to start the double play.
"I went on my own," Tulowitzki said. "I figured it was the right play because Matt normally puts the ball in play."
Kata tripled into the right-field corner and scored on Sanchez's ground out in the first inning as the Pirates took a 1-0 lead.
Colorado starter Ubaldo Jimenez allowed a two-out double to Adam LaRoche in the first and then settled down, allowing only three hits after the first inning. He allowed a run in seven innings, and struck out four without allowing a walk.
Tulowitzki hit a 445-foot home run to center with two outs in the seventh to give the Rockies a 2-1 lead.
Pittsburgh starter Matt Morris was just as stingy, giving up two runs, but only one earned with seven hits in seven innings.
The Rockies left a runner on third base when Garrett Atkins drew a leadoff walk and moved to second on a ground out and to third on a wild pitch. But Morris fanned Ryan Spilborghs and Yorvit Torrealba to end the inning.
"These losses hurt," Tulowitzki said. "This loss really hurts."
