Notes: Holliday OK after dugout misstep

Notes: Holliday returns to lineup

DENVER -- Matt Holliday arrived at Coors Field with a welt on the top of his head and a bemusing explanation of why he had to leave after the fourth inning of the Rockies' 4-2 loss to the Reds on Friday night with a head contusion.

Holliday said he bounded down the dugout steps after the top of the fourth inning hoping to get to the video unit so he could study his previous at-bat.

"There was something on the last step, so I was going to jump over, skip a step," Holliday said. "As I jumped, I hit the top, the brick, of the doorway. So that's what happened."

There were no witnesses. Teammate Todd Helton saw Holliday as he lay dazed at the bottom of the dugout stairs. Rockies trainer Keith Dugger and one of the Rockies' team doctors checked Holliday to make sure he didn't have a concussion.

Holliday left the stadium immediately after the game and did not speak to the media until Saturday afternoon. But all was fine, and he was back in the starting lineup for Saturday night's game against the Reds.

Rockies manager Clint Hurdle had no qualms removing Holliday from Friday's game.

"That's what our trainer felt best doing, and they handled it the way they deemed to be professional, for his well being, first and foremost," Hurdle said. "He'll be OK today. Keith put him through a battery of tests and felt comfortable sending him back out there."

Fogg's comeback: Right-hander Josh Fogg pitched five innings and gave up three runs, two earned, with three strikeouts and no walks in a rehab start for Triple-A Colorado Springs at Oklahoma on Saturday night. He threw 80 pitches, 53 strikes.

Fogg is on the 15-day disabled list with a strained left groin, but is eligible to be removed on Thursday.

However, it isn't clear if Fogg will rejoin the rotation. Right-hander Taylor Buchholz, who moved into the rotation when Rodrigo Lopez was out with a forearm injury and slid into Fogg's spot for the last two starts, has had his moments. Also, Hurdle called for slumping rookie Jason Hirsh to perform better.

"We need to make sure he's healthy," Hurdle said of Fogg, not wanting to offer details of the plan. "We're going to have six starters here in a matter of time, and we're only going to use five. I will say that."

On the Rox: Double-A Tulsa right-handed reliever Juan Morillo, who went 3-0 with a 0.69 ERA and held opponents to a .196 batting average in nine games in May, was chosen the Rockies organization pitcher of the month. Class A Asheville second baseman Daniel Mayora was chosen the organization's player of the month after batting .375 (36-for-96) with 11 doubles, three home runs, 20 RBIs and 23 runs scored in 25 games. ... With third baseman Garrett Atkins out of the lineup as he recovers from his early season slump, Hurdle put rookie shortstop Troy Tulowitzki in the fifth spot. Hurdle earlier had balked at moving Tulowitzki there to bat behind Helton. The fifth batter often faces pressure because teams pitch around Helton. ... In the 28 games before Saturday night's contest, the Rockies were hitting .216 (50-for-132) with runners in scoring position. Only the Reds (.208) and Blue Jays (.207) had lower averages in the Majors.

Up next: Lopez (2-0, 2.35 ERA) will start against Reds right-hander Matt Belisle (5-4, 4.26) in Sunday's three-game series finale.
