Collin Morikawa ran off four straight birdies after making the turn Friday, finished with another birdie and shot 6-under 66 to build a three-shot lead in the second round of the Workday Charity Open at Muirfield Village in Dublin, OH. Louisville area native Justin Thomas fired a six under 66 Friday and is tied for second with Kevin Streelman at 10 under. Kentuckian JB Holmes withdrew before the second round due to a shoulder injury and Nashville’s Brandt Snedeker sits at one under par after two rounds. Weather forced a couple of delays with the remainder of the second round to conclude Saturday morning before the cut is made for the third round.
