A.J. Burnett is slated to make his next rehab start Monday with Triple-A Indianapolis. The right-hander was charged with eight runs — five earned — on five hits in 1.2 innings Wednesday for Single-A Bradenton, walking one and striking out four. Manager Clint Hurdle said Thursday that Burnett pitched a clean, 10-pitch first inning but got into trouble in the second when some young players "ambushed him, got on bases and things started happening."

As Burnett approached the 20-pitch mark, special assistant to the general manager Jim Benedict noticed that the foundation of Burnett`s delivery wasn`t where it needed to be.

"(Burnett) just tried to power through and focus on getting his pitch count up. The guys kept taking swings, and they kept hitting balls and finding grass," Hurdle said. "He wasn`t happy about it, but there`s no injury."
