Tyrrell Hatton's shop-bought putter continued to prove a real bargain as the Englishman surged into a share of second place in the Dell Technologies Championship.
Hatton carded eight birdies in a flawless second round of 63 at TPC Boston to join Ryder Cup team-mate Justin Rose on 10 under par, a shot behind Players Championship winner Webb Simpson, who holed from 70 feet for an eagle on the 18th in his 63.
Rory McIlroy finally got going, shooting four under to move up to tied 21st.
European number one Tommy Fleetwood is three shots off the pace following a 65, with Spain's Rafael Cabrera Bello part of a nine-way tie for seventh on six under as he tries to enhance his case for a Ryder Cup wild card.
Tiger Woods and McIlroy are both seven shots off the pace on four under after rounds of 66 and 67 respectively.
Frustrated by poor putting during last week's opening FedEx Cup play-off event in New Jersey, Hatton sent his caddie to a Golf Galaxy store to buy a new putter, using a video app to make the selection.
"I was too embarrassed to go into the store to buy a putter. Obviously, he made a good choice," said Hatton, who posted a picture of the receipt on Twitter which showed that the club cost him $149 before taxes.
Well that’s the best $172 I’ve ever spent 😂😂🙈— Tyrrell Hatton (@TyrrellHatton) August 26, 2018
Was so nice to hole some putts again today, new putter worked it’s magic!

That proved to be money well spent as Hatton carded a closing 65 in New Jersey and six days later the same club helped Hatton one-putt six holes in succession, including a par save on the par-five second after hitting his second shot into the water.
