This is sort of getting ridiculous.
Jason Day followed up his opening-round 61 with a 63, tying the PGA Tour record for the lowest score after two rounds, sitting at 18-under and holding a five-stroke lead at the midway point of the BMW Championship, the third leg of the FedEx Cup Championship.
Day leads the points chase already, and if he wins the tournament he could climb as high as No. 1 in the world depending on where Rory McIlroy and Jordan Spieth finish.
Day actually made a bogey on Friday – a 5 on the par-4 No. 13, but he shot a birdie ahead of it and two more afterwards. He added an eagle on No. 18 for good measure.
At 18-under, his lead is five over Brendon Todd and Daniel Berger. Todd also shot a 63, Berger a 64 on Friday. Kevin Na and Jordan Spieth are tied for fourth at 11-under, seven strokes off the lead.
Spieth overcame back-to-back bogeys on 12 and 13 thanks to a strong finish of birdie-eagle on 17 and 18.
