Matt DiBenedetto getting a new crew chief starting in the All-Star Race

Starting in the All-Star Race at Texas, Matt DiBenedetto will have a new crew chief.

Jonathan Hassler will now be calling the shots from the #21 pit box. Hassler is a Penske engineer who was a fill-in crew chief for him at Martinsville where he finished 12th.

Starting with this weekend’s all star race in Texas, Jonathan Hassler will assume the crew chief role for our 21 Mustang.
We want to thank Greg Erwin for leading our team for the previous three seasons.
