ST. LOUIS -- Adam Wainwright will make his next scheduled start on Tuesday, but the Cardinals have not ruled out the possibility of building in extra rest for the right-hander if there are continued concerns of fatigue.
While Wainwright has downplayed a connection between his workload (464 2/3 innings since the start of 2013) and his second-half slide (3-5 with a 4.68 ERA and 1.94 strikeout-to-walk ratio), general manager John Mozeliak acknowledged that the two may not be entirely unrelated.
"I think there are a lot of people speculating on a lot of things going on with Adam," Mozeliak said on Friday. "Fatigue certainly could be a plausible answer. Going back to the All-Star break and not being able to take full advantage of that, to rolling into being how he's used, is something you can always look back at.
"If there is a way to getting him extra rest, we'll certainly have to consider it. But this time of year, the type of race we're in, it's going to be hard to do."
The Cardinals are not yet sold on adjusting Wainwright's September schedule and will see how he fares against the Pirates next week before making any decisions. If the Cardinals keep with their current rotation order, Wainwright is set to make another five starts before the end of the regular season.
