JT Poston pulls ahead by four at halfway point of John Deere Classic

JT Poston shot a second round score of 65 to be four strokes up heading into the weekend at the John Deere Classic.

The in-form 29-year-old had seven birdies on Friday at Silvis, Illinois, to move to 15 under par despite a bogey on the par-four sixth hole.

"I feel great," Poston told pgatour.com. "My last few rounds out here have been great going back into last week, so just going to try and keep riding that momentum and doing what I'm doing."

Poston finished second in last week’s Travelers Championship after failing to capitalise fully on an opening 62, and he added: "Last week, the one thing I think I learned after playing well Thursday was to try and keep the pedal down.

"I think this golf course may yield a few more birdies than last week but at the same time, you got to go out there and hit some golf shots to stay aggressive. I was able to do that, which is nice."

His six-under-par round was matched by fellow American Denny McCarthy, who lies second on 11 under after a bogey-free effort.

Argentina’s Emiliano Grillo shot 64 to take his place in a group at 10 under, alongside Austria’s Mathias Schwab and another American in Christopher Gotterup.

The lowest rounds of the day were a pair of seven-under-par 63s by Maverick McNealy and Kelly Kraft, who are both in an eight-strong group at nine under which also includes England’s Callum Tarren.

Defending champion Lucas Glover missed the cut by one shot at two under despite a 66.
