DENVER -- Talk about new blood.
Rockies rookie infielder Ryan McMahon has hit .324 -- with memorable homers on Friday and Saturday in wins over the Dodgers -- in 15 games (eight starts) since being recalled from Triple-A Albuquerque.
Outfielder David Dahl has hit .261 with a .370 on-base percentage in eight games (six starts) since his latest recall from Albuquerque.
The first question in today's Edward Jones Beat Reporter's Inbox echoes what many fans wonder: Will we be seeing more of them?

A couple days ago, I asked manager Bud Black during his pregame news conference about Dahl, who has started at all three outfield positions since his return -- including three times in left, where Gerardo Parra also starts.
What I've noticed is Black doesn't make declarations about whether young players are considered starters, for good reason. At catcher, for example, Tom Murphy received several starts when he was hitting, but after he struggled, he was sent back to Albuquerque, and Chris Iannetta and Tony Wolters reassumed their rotation with no fuss.

Dahl's starts came while Parra was going 0-for-11. The goal is to make sure both can be used, not to anoint a long-awaited former top pick a starter.
"I don't think there's a need to do that," Black said. "That's just me. I don't think you have to give any hard absolutes on anything.
"With any young player, there is a learning curve that takes time to develop into really a true big leaguer. Some guys, it happens fast. But most players, it takes a while to really entrench yourself as a big leaguer."
With Dahl and Parra in the outfield and McMahon in the infield, they have power and run-production potential that Black will plan to use either in the lineup or off the bench. The pace of close games figures to continue, so there will be a balance of starts in hopes that all will be able to contribute, whether they start or come off the bench in a given game.

Since his July 14 return from Albuquerque, the Rockies have won all five of Jon Gray's starts. Just one of them -- four runs and eight hits in 5 2/3 innings on Friday -- was not a quality start. If you look back to last year, Gray didn't give up more than three runs in any of his final 13 starts.
The answer to the "can" part is yes. As for the "will," we'll find out through a fun rest of the year, won't we?

 
Through nine games at Triple-A Albuquerque, Matthew Holliday is hitting .242 (8-for-33) with three doubles, two home runs and 10 RBIs. He also has seven walks to six strikeouts. Numbers-wise, it's headed in the right direction for him to make it as mainly a right-handed bat off the bench.
But it's going to come down to what the numbers don't tell us. Are the legs strong? Are there elements of the swing that the combination of detailed scouting and Major League pitching ability can exploit? The Rockies need to be confident in the answers before calling upon him, which is why they haven't rushed him based on a few solid games in the Pacific Coast League. But the early results look promising.

Wade Davis, coming off a solid ninth inning to earn the win Sunday, has struggled with delivery issues dating back to last season. They just have shown up more in the results this year. But this is where being a veteran helps. He can push aside all the unnecessary emotion and theories and work on the true delivery issues.

Ranked as the Rockies' No. 2 prospect, Peter Lambert, 21, is on the Major League radar, but it would likely take injuries to the rotation to make him a clear candidate to pitch in September. Activating him would also mean clearing a spot on the 40-man Major League roster (something that will have to happen to get Holliday in a Rockies uniform).
But even if he isn't called up, I could see the wisdom in carrying him with the big club and continuing his work. He could always be activated, if necessary, but even if that doesn't happen, there is value in doing his work with pitchers preparing for all-important games.

 
Like your thinking here. This is what they wore the night Todd Helton hit the walk-off homer off the Dodgers' Takashi Saito that triggered the run that eventually lifted the 2007 Rockies into the World Series.
But that uniform is not listed among the uniforms in the team's style guide -- just four (white pinstripes, black vests, purple and road gray) are -- and it hasn't been for several years. I am not clear on what it would take to bring it back for a late-season run, or even if it is allowed.
