Cardinals Recall Righty For "Meaningful Role" Down The Stretch

The St. Louis Cardinals are working on preparing their pitching staff for the upcoming postseason. As a means to that end, they've recalled right-hander Dakota Hudson, for a "meaningful role" down the stretch. 
Hudson has already started 25 games for the Cardinals this season, and holds an 8-7 record, with a 4.16 ERA. His control of the strike zone is what's held him back, with a mediocre 77:58 K/BB ratio in 134 innings.

But the real reason for his promotion at this time is quite possibly to give veteran Adam Wainwright a bit of rest heading into the playoffs.
After another season approaching 200 innings, 41-year-old Wainwright has been experiencing a "dead arm" period, and manager Oliver Marmol said one potential role for Hudson would be to plug him into the rotation to give Wainwright an extra day of rest. 

“He could be used a couple of different ways,” Marmol said of Hudson. “Insert him into the rotation to buy people a day. We can use him as long relief. We could use him for an inning... 
“I’d like to give him the opportunity to continue to contribute to us winning, and have a role that is meaningful.”

To make room on the roster for Hudson, the Cardinals optioned lefty Packy Naughton to the Triple-A Memphis.
