VYSOKY UJEZD, Czech Republic — Thomas Pieters of Belgium shot a 7-under 65 on Saturday despite being penalized for hitting the wrong ball, taking a one-stroke lead after the third round of the Czech Masters.
Pieters began the round one shot behind overnight leaders Matthew Fitzpatrick and Pelle Edberg but made an eagle on the par-5 first hole and continued with four birdies on the next nine. His lead could have been bigger if not for taking a double bogey on the 11th after playing the wrong ball in the rough.
"It's never happened to me before," Pieters said.
