Tiger Woods has notably struggled with his putter on Tour this season. On Tuesday at the Quicken Loans National, he was experimenting with a mallet putter on the practice green.
Woods was using a TaylorMade Ardmore 3 putter at TPC Potomac instead of his Scotty Cameron Newport 2, for which he used to win 13 of his 14 major titles (he used another Scotty Cameron Newport model to win the 1997 Masters).
Here's a look:
First putter out is the TaylorMade. Looks like an Ardmore with a single white sight line down the middle of the flange.
