We take out weekly look at middle infielders every Wednesday. All stats and notes are through games of Tuesday, Aug. 30.

When tackling the task of the potential September call-ups, we discovered something pretty important: The true impact Fantasy players are already in the big leagues.

That might sound like a "no sh...oot," but this isn't as cut and dry as you might think.

Guys like B.J. Upton and others still could help a Fantasy team in crunch time, but it seems 2005 has been the year of the rookie and all the impactful minor-leaguers have already been called up. With a so-so free-agent crop on tap this winter and a slew of teams in the hunt around the trading deadline, a stale market forced franchises to find answers from within. Read: Oakland, Atlanta, New York (both), Anaheim, et al.

So, what usually is a frenzy of top arrivals in September, looks more like AL-only and NL-only roster fillers and fliers for us right now.

There are still some sleepers to be gobbled up in the coming weeks, but their potential Fantasy impact is limited to playing time.

Working off the MLB.com 40-man rosters -- because teams tend to avoid adding top prospects to the 40-man roster this time of year, if they can avoid it -- here is our look at those who could get a September call-up among middle infielders:

Bleacher Banter

Tracy, N.H.: Now that Nomar Garciaparra is healthy, should I start him over Jhonny Peralta or keep Nomar benched?

E.M.: While they both hold similar Fantasy potential because of their pop, the Indians are in the thick of a pennant race and will ride the bat of their emerging No. 3 hitter here on out. Garciaparra's Cubs have folded their tents and will begin evaluating players for 2006, so he is no certainty to play every day. Nomar is a free agent, by the way. Anyone facing this choice should start Peralta over Nomar in all leagues going forward.

Steve Gerkin, Orlando, Fla.: I was thinking about dropping Geoff Jenkins and/or Tony Clark for Mike Jacobs and/or Clint Barmes. I have Miguel Tejada at short and just picked up Jose Reyes at second (dropping Mark Grudzielanek). Catchers are Michael Barrett and Bengie Molina. My best chances of gaining ground are in HRs and RBI.

E.M.: Go for it. Barmes is a top prospect who will play every day in his return late this week, while Jacobs has been thrown right into the fire and has good pop for a catcher. We say they are more for depth, though, as your starters are solid.

Alex Tzoumas, New Hyde Park: I am in a 12-man keeper league in which everyone keeps four players each. I'm definitely keeping A-Rod, but with guys like Adam Dunn, A.J. Burnett and Eric Gagne, I have no room to keep Felix Hernandez or Jhonny Peralta. (Gagne because my league's points award closers like him.) Do you think Peralta or Hernandez should be in my list?

E.M.: I rarely ever bother with keeper questions this time of year, especially when you're talking about someone like Gagne, who will at least some portion of 2006 (and perhaps the whole year). Also, you never know where Burnett could wind up in free agency. At this point you cannot keep Gagne because of the uncertainty of his recovery. Also, imagine if you decide to keep Burnett and then he goes and signs with the Reds? Peralta and Hernandez should be in your mix over those two question marks, but any number of events could unfold between now and 2006.
