Marco Andretti posted the fastest Indianapolis 500 practice speed of the month Monday, turning a fast lap of 225.100 mph on the 2.5-mile oval.

Defending series champion Ryan Hunter-Reay was third at 224.386. Australia's Will Power was fourth at 223.784 and Panther Racing's J.R. Hildebrand was fifth at 223.624.
