Tony Kanaan took control of the ABC Supply Wisconsin 250 following pit stops by the leaders shortly before the halfway point at Lap 125. Kanaan currently leads Will Power, Ryan Briscoe, Scott Dixon, and Juan Pablo Montoya.
The first stint of the race was headlined by two-time defending Milwaukee race winner Ryan Hunter-Reay. Needing a big result to keep his championship hopes going, Hunter-Reay charged from 19th on the grid to 11th over the opening 25-30 laps.
Meanwhile up front, pole sitter and Verizon IndyCar Series points leader Power built a lead of about one second over Kanaan while the entire field slowed down dramatically as the tires fell off on performance.
Pagenaud opened the first wave of pit stops on Lap 52, with Power and Kanaan coming in together at Lap 59. The latter two cycled back to first and second when Ed Carpenter went in at Lap 63, and a short time later, Kanaan went to the inside of Power in Turn 3 in an attempt to take the lead from him.
But Power was able to hang tough on the outside to keep the lead, and another attack from Kanaan on the very next lap ended the same way with Power maintaining control.
Power and Kanaan returned to first and second with Briscoe in third, Montoya in fourth despite hitting a wheel on his first pit stop (Race Control gave him a warning instead of a penalty), Helio Castroneves in fifth, and Hunter-Reay moving further up to sixth.
Around Lap 90, both Hunter-Reay and Josef Newgarden got past Castroneves for fifth and sixth respectively; NBCSN’s Kevin Lee later reported that Castroneves’ slide was due to understeer on his No. 3 Team Penske Chevy.
Shortly after Lap 100, the second wave of pit stops began. Kanaan went in for service at Lap 114, but Power opted to stretch his tires out to Lap 121. Unfortunately for him, that decision backfired as Kanaan passed Power on track to take the lead for the first time this afternoon.
