The Indianapolis Indians' Twitter account reported that Polanco leads all of Triple-A with a 196 wRC+, according to FanGraphs.com, meaning he's created 96 percent more runs for his club than the average Triple-A player.
Meanwhile, Double-A Altoona shortstop Alen Hanson went 3-for-4 with a solo home run, stole two bases and turned four double plays as the Curve beat the Richmond Flying Squirrels, 3-0.
Hanson, the Pirates' No. 5 prospect and No. 58 on MLBPipeline's Top 100 Prospects list, is now batting .273/.309/.448 with four homers, 19 RBIs and 10 stolen bases.
The 21-year-old is on pace to post similar numbers to those from his 2013 campaign, which came on the heels of a breakout '12 season in which he hit .309/.381/.528 with 16 homers and 35 steals for Class A West Virginia.
