mlb 09/08/08 1:42 PM ET Jonathan Mayo is a senior reporter for]]> There have been several more intriguing prospects who've debuted in the bigs, either because teams took a little more time to announce their callups or because they were waiting for the first round of playoffs to end.

As always, a great guide is Lisa Winston's Movin' On Up.

This week's Exchange starts with the slew of young Brewers who are settling down in Milwaukee. Mat Gamel is the third baseman of the future, and if you needed to wait for him to get called up to officially put a claim on him, then wait no longer. Gamel is not going to play much right now, but he could be the starter in 2009 if he continues to make improvements defensively.

Catcher Angel Salome likely won't play much immediately, either, but he's definitely one to watch since he won the Double-A Southern League batting title with a .360 average and owns a .322 career mark in the Minors. Salome also slugged an impressive .559 this year, and there may be more pop to come. Move over, Jason Kendall; Salome could very well be the guy behind the plate for the Brewers in '09.

Alcides Escobar came up with Salome from Huntsville. Again, this is a guy who won't make much of an impact this year, but Escobar can hit for average (.328 in 2008, .292 for his career) and can run (34 SB in '08). I'm not sure how the Brewers will handle the shortstop situation, but you'll want to be there to reap the benefits when Escobar lands a starting job.

It looks like the Dodgers are giving Scott Elbert the chance to contribute as a lefty out of the 'pen right away. I don't think he'll be of much use for fantasy purposes this month, but he'll be an intriguing pick next year. With his past arm problems in the rear-view mirror, Elbert could challenge for a spot in the 2009 rotation. However, even if the team keeps him in a short relief role, he'll be one to watch. The left-hander posted a .157 average against and 46 Ks in 41 1/3 innings at Double-A Jacksonville this year, which gives you an idea of just how nasty his stuff is.

Like Matt Antonelli and Wade LeBlanc, Will Venable is getting a chance to show the Padres how he could fit into their future plans. So far, so good, as the outfielder has gone 10-for-31 (.323) over his first nine games. NL-only owners may as well take a flier on the 25-year-old, who batted .292 with 14 jacks and 58 RBIs in 120 games for Triple-A Portland.

I hinted last week that perhaps Rockies prospect Dexter Fowler would get called up, and the Rockies made it official shortly thereafter. He's not playing much just yet, but he's fair game for keeper-league owners. Trust me: Fowler is just going to get better and better.

St Louis' Jason Motte has closer of the future potential. He may be a little old for a prospect at 26, but he's relatively new to pitching after beginning his professional career as a catcher. Motte struck out a whopping 110 batters in 66 2/3 Triple-A innings this year, and he's already fanned four in 1 2/3 innings with the Cardinals. At the very least, he should be a setup guy worth owning in NL-only leagues in '09.

And I know he was up earlier in the year, but it's always worth keeping an eye on Max Scherzer. The flamethrower made a spot start on Sunday and struck out 11 in five innings. If that kind of production can't help you down the stretch, then my advice is of no use to you anymore.
