MYRTLE BEACH, S.C. — Michael Block won the PGA Professional National Championship in a playoff Wednesday to lead the 20 qualifiers for the PGA Championship.

The 38-year-old Michael Block, the PGA head professional at Arroyo Trabuco Golf Club in Mission Viejo, California, beat Jamie Broce with a 3-foot birdie putt on the second extra hole.

“It’s amazing to be sitting here as a national champion,” said Block, the former University of Missouri player who earned $75,000. “I wasn’t leading that championship for one second until that putt dropped on the second playoff hole.”

Block closed with his second straight even-par 72 at The Dunes Golf & Beach Club to match third-round leader Broce at 2-under 286. Broce, the University of Toledo coach, shot a 75. He bogeyed the final hole, lipping out a 4-foot par try.
