Michael Block last after Day 1 of Charles Schwab Challenge - ESPN

Michael Block, the teaching pro in California who finished tied for 15th at last weekend's PGA Championship, carded an 11-over 81 in the opening round of the Charles Schwab Challenge at Colonial on Thursday in Fort Worth, Texas.

Block was playing in the PGA Tour event on a sponsor's exemption he received after his inspirational finish at Oak Hill.

He's currenty last in the 120-player field.

His round included seven bogeys (including four in his first five holes) and three double-bogeys (including three in his final four holes).

There were highlights, though.

Block had two birdies and also made an impressive save on the par-4 10th after his tee shot flew way right and landed on a bridge cart path, where he hit wedge over a tree from 100 yards out to the front side of the green before escaping with a par.

Block is 19 shots behind leader Harry Hall. He'll begin play in the second round Friday at 9:48 a.m. ET.
