According to the St. Louis Post-Dispatch, "Lefthanded starter Mark Mulder is scheduled to make two more rehab starts before the end of the month and, according to pitching coach Dave Duncan, could join the starting rotation in the first week of September. Mulder will start Sunday for High-A Palm Beach opposite New York Mets starter Pedro Martinez, who also is on a rehab assignment. Barring difficulty, Mulder's next start will be Aug. 31 at Class AAA Memphis. He'll join the big-league team when roster expands Sept. 1. Duncan said Mulder's repaired rotator cuff "is not an issue. Has not been an issue at all. ... Everything as a whole has been better. His delivery, consistency, endurance. Everything is improving each time."
