Prospect Bethancourt among September callups

Catcher coming up Tuesday; Constanza, Terdoslavich, Jaime, Shreve also on way

ATLANTA -- Highly regarded catching prospect Christian Bethancourt will headline the list of Minor League players that will attempt to help the Braves gain a postseason berth in September. But when the rosters expand Monday, Bethancourt -- Atlanta's No. 3 prospect, according to MLB.com -- will not be among the first wave of additions who are expected to arrive from the Triple-A Gwinnett club.

Braves manager Fredi Gonzalez indicated a group of Gwinnett's players will arrive at Turner Field in time for Monday afternoon's series opener against the Phillies. Bethancourt will join Atlanta on Tuesday, after Gwinnett concludes its regular season Monday.

Along with Bethancourt, outfielder Jose Constanza and switch-hitting utility man Joey Terdoslavich will be the position players who will spend the season's final month on Atlanta's roster. The pitchers getting a call are right-handed reliever Juan Jaime and left-handed reliever Chasen Shreve.

Constanza and Terdoslavich are the only members of this group who have not spent time at the Major League level this year. But they have both been with Atlanta for extended stretches over the past few years.
