PALM BEACH GARDENS, Fla. –– Luke Donald is in contention at the Honda Classic, and he partly has technology to thank.

He’d been struggling with his putting – in the second round of the Farmers Insurance Open at Torrey Pines a few weeks ago, Donald didn’t have a single one-putt – so he sent off a video of his stroke earlier this week to Pat Goss, the head coach at Northwestern.

Goss told Donald that his sternum was moving a little during the stroke, which meant the head of Donald’s putter was exiting a little too far to the left.

“Just trying to stay a little more centered,” Donald said of his adjustment, which keeps the putter moving better down his line. The result? In two rounds at PGA National, Donald has made 245 feet of putts, which included three putts beyond 25 feet. He made five birdies on Friday, one day after making two in difficult, windy conditions playing in Thursday’s afternoon wave.

“That’s the magic of technology these days,” Donald said after Friday’s 67 moved him to 4-under 136 through two rounds. Second-round play was suspended by darkness on Friday, and of the players who finished 36 holes, Donald trails only Patrick Reed (134).

“You can get a quick lesson, and now it’s 240-something feet of putts I’ve made over two days. … That tip was obviously worth it. I told him, ‘You’re still useful. You might stick around for a little bit.’ ”

So might Donald, the former World No. 1 who has four top-10 finishes in his last five starts at the Honda, including a victory in 2006, when the event was played across the street from PGA National at the Country Club of Mirasol. Donald had missed the cut in his last three starts (Humana/Farmers/Northern Trust). His best finish of 2014-15 is a T-41 at the HSBC Champions in China.
