(Reuters) - Italy's Matteo Manassero blitzed the course as he hit an 11-under-par 61 on Friday for a one stroke lead after the second round of the DP World Tour's Jonsson Workwear Open at the Glendower Golf Club.

A career low round for the 30-year-old over the Johannesburg course included two eagles and seven birdies and took him to a 15-under-par two round total of 129.]
