Emotional club pro Michael Block toils during 11-over first round at Charles Schwab Challenge

(CNN) — Less than a week since his stunning performance at the PGA Championship, club pro Michael Block endured a tough first round at the Charles Schwab Challenge, shooting 11-over par.

Block earned hero status at last week’s major when he finished tied for 15th, dunking a hole-in-one on Sunday and later receiving a congratulatory text from NBA legend Michael Jordan.
