The Arizona Fall League is firing up for its 20th season and has broken out with new logos for its annual 40-game run. The league, started in 1992, is a melting pot where top prospects are observed by talent evaluators from early October till mid-November.

This year’s class will include P Gerritt Cole, the top overall pick in the 2011 First Year Player Draft for the Pittsburgh Pirates. This will be the third straight year that the draft’s top pick will play in the AFL, Cole following P Stephen Strasburg and OF Bryce Harper.

The top two prospects in all of baseball, Angels’ OF Mike Trout and Harper of the Nationals, will be teammates for the Scottsdale Scorpions. Trout and Harper go 1-2 in the prospect rankings for both and Baseball America.

The Arizona Fall League is under the radar for casual baseball fans as the MLB post-season plays out. But for prospect watchers and fans of teams that didn’t get to play in October, an eye should be kept on the Valley of the Sun as help for your club may be on the way.

The time to start following the action is now as the rosters are filling up. Check the AFL’s page and follow the Twitter feed for @MLBazFallLeague.
