Tiger Woods' steady climb up the leaderboard on Friday at the 2019 Masters was fueled by a flurry of birdies. 

After starting the day T11 with an opening round 2-under-par 70 on Thursday, Woods roared out of the gate Friday afternoon. The first three holes he went par-par-par before he finally got a birdie putt to fall on the par-3 4th hole. He followed it up with a bogey on the par-4 5th, but then found another birdie -- this one from across the green -- on the par-3 6th hole.

Woods kept with that pattern as he finished his first nine when he posted a backbreaking bogey on the par-5 8th hole, then followed it up with a birdie on the par-4 9th hole to get him to 1-under on the day. If you thought his birdie on No. 6 was long, check the distance this one traveled.

Woods didn't slow down to open the second nine, either. He doubled up his birdie count from his first nine, in fact, and it started at No. 11 when he gave himself a manageable birdie chance at the par-4 11th hole.

Woods' preternatural ability to bounce back from bogeys on the day had nothing on his ability to bounce back from sliding security officers, though. No, seriously -- a security officer attempting to protect Woods accidentally slid into him after his approach shot on No. 14. After he managed to escape serious injury, he found his penultimate birdie of the day which moved him to 3-under.

Woods showed no signs of being slowed by the sliding security guard when he carded a birdie on the par-5 15th hole. He showed all the Tiger-like energy we've come to expect when he's really in the zone, too. When he walked this one in, it came replete with a signature fist pump and raucous cheers from the patrons ensued.

Woods finished the day 4-under and carded a 68, which put him just outside the top-10 to T6. At 6 under on the tournament, he'll enter the weekend just one stroke off co-leaders Brooks Koepa, Jason Day, Adam Scott, Louis Oosthuizen and Francesco Molinari.
