The Atlanta Braves are moving to a six-man rotation for two weeks.
Manager Fredi Gonzalez says he'll pick the best five starters at the end of August.
The Braves created a surplus in their rotation last month by trading for Paul Maholm, signing Ben Sheets and moving Kris Medlen from the bullpen. Right-hander Tommy Hanson, who leads Atlanta with 12 wins, returns from the disabled list this week and will start on Friday against the Dodgers.
Medlen is 2-0 while allowing only three earned runs in three starts. Gonzalez says Medlen will stick in the rotation if his success continues. Sheets is 4-2 with a 2.13 ERA in six starts in his comeback from elbow surgery.
The six-man rotation includes Tim Hudson, Mike Minor, Maholm, Sheets, Medlen and Hanson.
