Matthew Fitzpatrick and Pelle Edberg both shot a 5-under 67 on Friday to share the lead after the second round of the Czech Masters.
It was the second flawless round at the Albatross Golf course near Prague for the 20-year-old Fitzpatrick.
The Englishman holed a 20-foot putt for eagle on the par-5 12th and finished his round with his third birdie of the day on the 18th for an 11-under total of 133.
The 36-year-old Edberg of Sweden had six birdies, including four on the front nine, and a bogey. Thomas Pieters of Belgium was one shot back after carding a 68.
Both Fitzpatrick and Edberg are seeking their first European Tour victory.
