Both have dealt with injury issues this season. Wheeler had a knee injury and Kintzler, who was in the Brewers' bullpen on Opening Day, recently had surgery to repair a stress fracture in his right arm.
Scarpetta rejoined Double-A Huntsville on Tuesday, as he was activated from the disabled list.
Outfielders Mike Trout (Angels) and Bryce Harper (Nationals), the two top-rated prospects in baseball according to MLB.com, headlined the list of players headed to Arizona this fall.
"As we make final preparations to celebrate our 20th season, it is rewarding to know organizations continue to assign their top prospects to the Arizona Fall League," said
AFL director Steve Cobb. "The 2011 rosters are deep and talent-laden and could become one of the most impressive classes we've showcased in Arizona."
Bradley donned a Brewers jersey for the first time Tuesday and was introduced to the local media in a press conference at Miller Park. He is one of two 2011 first-round picks on the Peoria Javelinas roster, which is comprised of Brewers, Cardinals, Mets, Mariners and Padres prospects.
Mariners first-round pick Danny Hultzen, the No. 2 overall selection out of the University of Virginia, also is on the roster.
Until play begins on Oct. 4, Bradley will join fellow Brewers first-rounder Taylor Jungmann in the Instructional League.
Bradley said his biggest focus was on improving his consistency as a pitcher.
"Being able to go out there every fifth day and to consistently deliver those pitches, to the best of my ability," Bradley said. "You can always get more refined, you can always get sharper. That's just my goal, to get better every day."
Brewers scouting director Bruce Seid talked Tuesday about scouting and drafting Bradley, who fell to Milwaukee at the 15th pick in the first round.
"I remember seeing him in the Cape Cod League all-star game last year, and not really knowing who Jed was at that time, I said, 'This is a guy we want on our wish list for next year,'" Seid recalled. "I've been saying that all along, and here he is today. So, you know, wishes do come true."
