Joey Logano picked up his third Xfinity Series win of the season by throwing a big block on the final lap at Talladega Superspeedway.

Logano was the leader on a restart with eight laps remaining Saturday. He had Elliott Sadler hooked to his bumper as drivers jockeyed for position.

An outside lane formed led by Chris Buescher, a teammate of Sadler's at Roush Fenway Racing. As the cars circled the track for the final lap, Sadler had no room to make a move for the lead, and separated from Logano's bumper.

Buescher's pack surged forward, and Logano slid up the track to cut off the momentum.

The block allowed Logano to seal the win.

Buescher and Sadler faded to sixth and seventh.
