The Phillies will add six minor-league players as September call-ups, a group that includes many familiar names and two intriguing new ones.

Catcher Cameron Rupp, a former third-round pick who ascended to the top of the organization's catching ladder with a solid season, was added to the roster. He is joined by infielder Freddy Galvis and pitchers Tyler Cloyd, Luis Garcia, Mauricio Robles and Joe Savery.

A notable omission from that list is enigmatic reliever Phillippe Aumont, who apparently will be sent home. Aumont appeared in 22 games for the Phillies earlier this season but could not find the strike zone at triple-A Lehigh Valley following a July demotion. He walked 36 in 34 2/3 innings. The 24-year-old faces an uncertain future in this organization.

Rupp and Robles are the only players yet to see big-league time. Robles, a lefty, pitched without control like Aumont. He walked 31 in 38 innings with the IronPigs but managed a 1.42 ERA. The 24-year-old was a waiver claim from Seattle last winter. Scouts are impressed by his hard fastball, but, like Aumont, he has failed to harness it.

Rupp, 24, batted .260 with a .760 OPS across double-A Reading and triple-A Lehigh Valley. He bashed 14 homers and developed a reputation as a reliable backstop. Carlos Ruiz is a free agent at season's end, and while it is difficult to imagine a catching tandem of Erik Kratz and Rupp, it is a chance for Rupp to taste the majors and gain comfort in case he's needed in 2014.

Top prospect Maikel Franco was not among the promoted, although Ruben Amaro Jr. said his name was "discussed internally." Franco ended his season Monday at double-A Reading with a 3 for 4 performance. He batted .320 with a .926 OPS and 31 homers.

Part of the issue is playing time; the Phillies want an extended look at third baseman Cody Asche. Franco played eight games at first base for Reading, and asking the 21-year-old prospect to play an unfamiliar position at the major-league level is an unfair situation.

Franco will play winter ball in the Dominican Republic. He will likely attend big-league camp in spring training.

In addition, Lehigh Valley manager Dave Brundage will be in uniform as an extra coach during the final month.
