The Chicago Cubs will use a six-man starting rotation over the next few weeks to give their starters some extra rest, according to Joe Maddon.

Adam Warren was sent to Triple-A Iowa to be stretched out and then will be recalled to start. Maddon says the Cubs will use a six-man rotation heading into the All-Star break, and perhaps after it, as well.

"This is when it gets a little bit sticky at this time of the year," Maddon said. "You want to make sure they're healthy and well ... I love it. I've been part of this before, primarily after the break."
