No clubs expressed interest in right-hander Shaun Marcum before Friday's deadline for contending teams to trade for players and have them eligible for postseason play. Manager Ron Roenicke hinted that trades are still possible in September.
For that to be true, Marcum would have had to clear waivers. Melvin declined to say whether Marcum had cleared, citing MLB rules.
Outfielder Norichika Aoki missed a second straight start with a stiff neck, suffered in a collision with Nyjer Morgan at Wrigley Field on Thursday.
"He's still a little sore, but he's fine," Roenicke said of Aoki. "He'll be able to pinch-hit tonight if we need him, which is encouraging. Hopefully we get him back in there [on Sunday]."
