Ed Carpenter's #20 Fuzzy's car has retired from the race. That's what you say when a car is dropping out. It doesn't mean Ed is retiring from racing, it just means he's done today.
Ed completed 98 laps before going out for mechanical issues, and currently sits in 31st place. His teammates JR Hildebrand and Josef Newgarden are still out on the field, running 6th and 3rd respectively.
Buddy Lazier is also currently out for mechanical reasons, but no word has come down on whether he's out.
