SPRINGFIELD: Unheralded Robert Streb matched the record-low round in major golf history on Friday with an astonishing seven-under par 63 to seize a share of the lead after the second round of the PGA Championship. Top-ranked defending champion Jason Day’s amazing run of seven birdies in eight holes to grab a share of third was overshadowed by a 29-year-old American on a rain-soaked Baltusrol layout soggy enough to surrender low scores in a wild afternoon of shot making. Back-nine starter Streb made a lone bogey and eight birdies, the last of them on a curling 21-foot putt at the par-three ninth to make history and match compatriot Jimmy Walker for the 36-hole lead at nine-under 131. “I was pretty excited about itI was waiting on it to break, waiting on it to break and it finally turned there at the end.” Said Streb “It was a great round. Happy to be part of that 63 club.” He added. Streb’s 63 was the 30th shot at a major but he was the 28th Player to achieve the feat, Fiji’s Vijay Singh and Australian Greg Norman having done it twice. British Open champion Henrik Stenson andrunner-up Phil Mickelson each did it two weeks ago at Royal Troon.
