In September, Ambrose skipped a second opportunity to drive the No. 77 car because his wife Sonja gave birth to their daughter Adelaide on the same day as the Cup race at Dover. Ambrose finished the 2007 season 8th in the points standings, highest of any driver not also competing in the Nextel Cup, and finished second behind David Ragan in the Rookie of the Year standings. On Sunday 20 April 2008 Ambrose was involved in a racing incident with Boris Said in the Busch Series event in Mexico. Ambrose admitted "getting into the back" of road course specialist, Said, causing Said to wreck and ruining his chances at a race where Said has consistently finished in the top 10. After the race Said claimed that he was not mad at Ambrose, but wanted to apologize to (Ambrose's) crew chief, Gary Cogswell because it was going to "cost him a car," implying that Said will wreck Ambrose intentionally next time they find themselves on a NASCAR track together. Even though NASCAR said that Boris just wrecked himself by getting loose, and that Ambrose has repeatedly apologized, in numerous subsequent public appearances, Said has not backed down in his threatening of Ambrose, at one point suggesting he would not apologize but preferred to "beat (Ambrose's) ass".
