DUBLIN, Ohio — Charl Schwartzel made sure one hole didn't ruin an entire round Thursday in the Memorial. Schwartzel hit the ball so consistently well at Muirfield Village that the former Masters champion twice had stretches of four straight birdies. And when he made a double bogey with an 8-iron in hand and his ball on a tee toward the end of the round, he got rid of that bad taste with one last birdie for a 7-under 65.
