The big names of IndyCar Series racing keep dropping out of Sunday's Grand Prix of Baltimore.
Reigning champion Ryan Hunter-Reay's No. 1 DHL Chevrolet stalled out on the opening lap and after climbing back into contention later on, finally ended his day on the 42nd lap with what he called "electrical issues."
On the 53rd lap, it was pole sitter Scott Dixon's turn. Coming down a straightaway, Dixon's Target Chip Ganassi's No. 9 Honda was forced into the wall when archrival Will Power had maneuvered in front of him, though Power's Team Penske No. 12 Chevrolet brushed the wall and was able to continue. Power was later given a drive-through penalty for Sunday's incident, causing him to drop out of contention.
Dixon, whose pit road collision with a member of Power's crew last week resulted in a drive-through penalty and caused him to lose the GoPro of Sonoma Grand Prix to Power, had words with his fellow driver as he walked in the pit road area near the warehouse.
Earlier in the race, Dario Franchitti also was forced to end his day early because of mechanical malfunction.
