There are many Brewer farm hands playing in one of the various winter leagues running at the moment. MLB.com has made it easy on us this year, giving us a page for each franchise. The most notable development for the Brewers so far is, unfortunately, how many guys who were supposed to be on the field are down and out with injuries. This is especially true at the premier postseason destination, the Arizona Fall League, where top prospects Mat Gamel, Angel Salome, Taylor Green and Jeremy Jeffress have all gone home for the year after seeing limited or no action.

There have been some notable performances (all stats are through action on 11/20):

• Lorenzo Cain, long a guy known more for his tools and projectablity than his production, is following up his strong regular season with a fantastic postseason. He's hitting .333/.382/.635 with 5 HR and 4 2B in 63 AB's, which represents a pretty good power surge from previous performances. Some of that is probably the parks he's playing in, but it's a positive development none the less. Next thing he needs to improve on is taking more walks, because 4 in 67 PA's isn't going to cut it.

• Brent Brewer is finally starting to show a little bit of the promise that led to his being selected in the second round of the 2006 draft. His regular season was disappointing, but so far in Arizona he's hitting .300/.344/.700 with 3 HR and 3 2B in 30 AB's. That's a very small sample, but any positive with Brewer at this point is going to stand out. He may be playing himself into a promotion to AA to open next year.

• OF prospect Caleb Gindl is having a solid, though unremarkable run in Hawaii. Fellow OF Logan Schafer is having a similarly decent run in Hawaii, though his walk rate is trending up, which is good.

• Until very recently, SS Alcides Escobar was having a terrible time in the Venezuelan Winter League, but 11 hits in his last 31 AB's has his line up to a moderately respectable .235/.305/.318. On the positive side, he's taking more walks than he generally has in the past. Still, that sort of production doesn't exactly scream "ready for the big leagues" does it?

• On the pitching side, one of the few top arms in the system having a good run is Omar Aguilar, who is following up a breakout campaign this last year with some good pitching in Arizona. A 12/4 K/BB ratio and 1.21 WHIP in 11 2/3 IP is pretty good for a guy in Arizona with less than 40 innings over A ball under his belt.

• Before being shut down with a tired shoulder, 2006 first round pick Jeremy Jeffress was getting hit hard in Arizona. His health and productivity are key to the Brewers right now, as he is one of the few impact pitching prospects left above rookie ball.

• Also in the "disappointing" category would be Alex Periard who's serving up HR at an alarming rate in Arizona and Cody Scarpetta is having trouble finding the plate in Hawaii.

• On a positive note, under-the-radar lefty reliever Mike Ramlow is following up a season where he opened a few eyes with a sound showing in Hawaii, though his walk rate in uncharacteristically high.

All in all, there isn't too much to get excited about here. A bad showing in one of the fall leagues doesn't mean much for long term projection.  A strong showing, however, may get you a longer look in spring training with the major league club and a poor one could have coaches and front office types longing to see a guy in the minors a bit longer. It's hard to say for sure what any of these performances mean until we see where they land to open next year.
