Perry and Langer each shot 5-under 67 to finish at 13-under 203 on TPC San Antonio's AT&T Canyons Course. Perry saved par on the final hole of regulation with an 18-foot par putt.
''I made clutch putts just to even hang in there with him,'' Perry said. ''Putter saved me.''
Perry extended his lead in the Charles Schwab Cup from 494 to 612 points entering the season-ending Schwab Cup Championship next week in San Francisco.

''He's going in with a very large lead,'' Langer said. ''I don't know if it's over. Theoretically, it's possible. I'm going to play as well as I can and see what happens.''
