The team scheduled a news conference for July 23 in Indianapolis to announce the deal.
"We're in good shape," Reutimann said after his win. "We basically shook hands and got things all lined up. I'll be at Michael Waltrip Racing next year. I may be cutting grass, but I'll be at Michael Waltrip Racing."
General manager Ty Norris confirmed an announcement is scheduled and that Reutimann and crew chief Rodney Childers will not be going anywhere.
"Both these guys proved tonight they deserve a contract," Norris said. "They deserve to be around."
