Worth noting

• Hurdle was coy when questioned about the progress of Gregory Polanco, the Pirates' top prospect and the No. 12 prospect in all of baseball, according to MLB.com's rankings. Hurdle said he last talked with Triple-A Indianapolis manager Dean Treanor on Sunday.

"He's moving along fine," Hurdle said. "Making progress."

Polanco, 22, is batting .345 with a .408 on-base percentage and .558 slugging mark in 50 games with Indianapolis. He has only played right field this season after mostly manning center the last two years.

• Charlie Morton's 61 percent ground-ball rate entering his start Wednesday is tops in the Majors since the start of 2013.
