Denny Hamlin isn't ready to say he's back, even after winning the pole for the Coca-Cola 600 with a record-setting qualifying lap Thursday night. He said it would take a win Sunday night or at another Sprint Cup race later in the season before he's willing to make that declaration. But Hamlin showed he continues to be on the mend after being sidelined for four races with a compression fracture in his lower spine following a March 24 crash involving former teammate Joey Logano.
