Rod Pampling
Making his seventh start in the Shriners Hospitals for Children Open, Rod Pampling followed a career-low 60 (to tie the course record set by J.J. Henry in 2014) with a second-round 3-under 68 to move to 14-under 128, good for a one-stroke lead over Brooks Koepka at the darkness-delayed Shriners Hospitals for Children Open.

Pampling’s 128 total is the lowest 36-hole score (any rounds) of the season, topping Scott Piercy’s 129 in the first two rounds of the Safeway Open.

Tom Lehman (125) owns the best opening 36-hole score at the Shriners Hospitals for Children Open (2001).

Pampling’s lowest opening 36-hole scores on the PGA TOUR:

128 – 2016 Shriners Hospitals for Children Open (60-68; TBD)
130 – 2006 DEAN & DELUCA Invitational (67-63; finished third)
131 – 2009 Quicken Loans National (67-64; finished T20)
131 – 2003 CareerBuilder Challenge (65-66; finished T21)
131 – 2005 Shriners Hospitals for Children Open (67-64; finished T16)

In six previous starts at the Shriners Hospitals for Children Open, Pampling’s best result is a T16 in 2005. He has not competed in Las Vegas since 2012 when he finished T68.

Pampling is making his third start of the season (Safeway Open/MC and Sanderson Farms Championship/T42) and 342nd on the PGA TOUR.

Pampling has two career PGA TOUR victories, but not since the 2006 Arnold Palmer Invitational presented by MasterCard (3/19/2006). He also won the 2004 The INTERNATIONAL (modified stableford format).

For the last two seasons, Pampling has secured his PGA TOUR card via the Tour. This past season, Pampling posted two top-15 finishes in the Tour Finals to finish 23rd on the final priority ranking order.

Pampling has missed the FedExCup Playoffs the last four seasons.

This marks Pampling’s second 36-hole lead/co-lead on the PGA TOUR, having opened 67-63 at the 2006 DEAN & DELUCA Invitational for the outright lead. He followed with matching even-par 70s on the weekend to finish solo third at Colonial.

Second-Round Lead Notes
The 36-hole leader/co-leader has gone on to win five of the last nine Shriners Hospitals for Children Opens: Webb Simpson (2013), Kevin Na (2011), Jonathan Byrd (2010), Marc Turnesa (2008) and George McNeill (2007).

Most recently, Tyler Aldridge, Chad Campbell, Morgan Hoffmann and Brett Stegmaier shared the second-round lead at the 2015 Shriners Hospitals for Children Open at 10-under 132. Eventual-champion Smylie Kaufman posted rounds of 67-72—139 (-3) and was seven shots back after 36 holes.

So far during the 2016-17 season, Justin Thomas (CIMB Classic) and Hideki Matsuyama (World Golf Championships-HSBC Champions) held the 36-hole lead/co-lead and went on to victory.

Brooks Koepka
Making his 65th PGA TOUR start, Brooks Koepka followed a bogey-free, 9-under 62 Thursday with a second-round 4-under 67, sitting one stroke behind leader Rod Pampling.

Koepka eagled the par-5 ninth and 16th holes Friday, marking his 40th and 41st eagle, respectively, on TOUR since the 2013-14 PGA TOUR season, tied with Dustin Johnson for most on TOUR during that timeframe.

Koepka is making his fourth start in the Shriners Hospitals for Children Open. Sandwiched between two missed cuts in 2013 and 2015 is a T4 effort in 2014.

Koepka is one of seven players who made the trip from Shanghai, China, after competing in last week’s World Golf Championships-HSBC Champions (T40), his only start of the 2016-17 season.

Koepka is one of three U.S. Ryder Cup team members in the field, in addition to Jimmy Walker and local favorite Ryan Moore. In September, Koepka made his first-ever start at the Ryder Cup, going 3-1 in his four matches in the United States’ 17-11 victory at Hazeltine, including a dominating 5&4 singles victory over reigning Masters champion Danny Willett. His three-point total (tied with Brandt Snedeker) was second only to Patrick Reed’s 3 ½ points.

Koepka is in search of his second career PGA TOUR victory (2015 Waste Management Phoenix Open).

Chris Kirk
A week after taking a share of the 54-hole lead at the Sanderson Farms Championship, Chris Kirk opened with a 131 total, equaling his second-best opening 36-hole score on TOUR, one behind the 130 he recorded at the 2013 Sony Open in Hawaii (finished T5). Kirk heads into the third round three back.

Kirk has top-10s in his first two starts of the 2016-17 season: T8 at Safeway Open and T2 at Sanderson Farms Championship.

Kirk is in search of his fifth PGA TOUR victory (2011 Sanderson Farms Championship, 2013 RSM Classic, 2014 Deutsche Bank Championship, 2015 DEAN & DELUCA Invitational).

Making his fourth start in the Shriners Hospitals for Children Open, Kirk has yet to crack the top 25 in three starts.

Aaron Wise
Making his fifth start on the PGA TOUR, sponsor invite Aaron Wise, starting on No. 10, played the back nine in 6-under, including eagles at Nos. 12 and 16. Wise was through 14 holes when play was suspended Friday. When he returned Saturday morning, he posted par-bogey-par-par and heads into the third round three shots off the lead.

The 2016 NCAA Champion will be a rookie on the 2017 Tour. He missed the cut at the Safeway Open and Sanderson Farms Championship. Wise lives in Las Vegas and works on his game with local teaching professional Jeff Smith.

Wise was a standout on the Mackenzie Tour – PGA TOUR Canada where he remains the youngest winner in Tour history. He won the 2016 Syncrude Oil Country Championship at the age of 20 years, 1 month, 10 days. In seven starts in Canada, he never finished outside the top 15, leading to his fourth-place finish on the Order of Merit to earn Tour status.

Pat Perez
Pat Perez (T5) posted a second-consecutive 5-under 66 Friday to move to 10-under 132. So far this week he is 8-under on the three par-5s at TPC Summerlin this week, including four birdies and two eagles.

Perez recently returned to action at the CIMB Classic (T33) for the first time since February, after sitting out much of the 2015-16 season due to a shoulder injury.

This week snaps a streak of three straight missed cuts for Perez in Las Vegas (2013, 2014, 2015). In 11 starts at the Shriners Hospitals for Children Open, he now has five made cuts, with a T14 in 2010 his best outing.

Additional Player Notes
With matching 5-under 66s in the first two rounds, James Hahn (T5) will make the cut for the first time in his three starts at the Shriners Hospitals for Children Open, having missed in 2013 and 2014.  His 132 through two rounds  equals his second-best opening 36-hole score on the PGA TOUR, second only to the 2013 CareerBuilder Challenge (130/finished T4).

Keegan Bradley, who is T5 after a second-round, bogey-free 6-under 65, finished No. 103 in the FedExCup last season, marking the first time since joining the TOUR in 2011 he has failed to advance at least to the second Playoffs event. With top-25 finishes in his first two starts this season – led by a sixth-place finish at the CIMB Classic – he is currently No. 17 in the FedExCup standings.

Chez Reavie posted a 10-under 61 to improve his score by 15 strokes from an opening-round 15-over 76. He entered the round ranked T141, but moved to T36. The 61 equals his career-best round on the PGA TOUR (61/2013 John Deere Classic).

Despite a double bogey on the par-4 12th hole, Brian Harman posted a 10-birdie, 8-under 63 to jump to T8. Harman had just 52 feet of putts made during an opening-round 70, but accumulated 154’11” feet of putts made Friday.

Celebrating his 38th birthday on Friday, Kevin Streelman (T46) posted a second-round even-par 71.

Greg Chalmers aced the par-3 fifth hole with a 7-iron from 190 yards en route to an even-par 71 (missed cut). The last ace at that hole in the Shriners Hospitals for Children Open was by Dan Forsman in 2003. Chalmers’ six aces on the PGA TOUR have come at the following events: 2004 John Deere Classic, 2009 Puerto Rico Open, 2011 Deutsche Bank Championship, 2013 Valero Texas Open, 2013 The Barclays, 2016 Shriners Hospitals for Children Open. Chalmers now moves to a tie for fourth for most holes-in-one by a PGA TOUR player (Hal Sutton and Robert Allenby lead with 10).

It’s been 23 years since Davis Love III (T46) won the 1993 Shriners Hospitals for Children Open and this week marks his 23rd start in Las Vegas. Since 1992, Love is a combined 160-under par in the event, the second lowest score to par behind Jim Furyk (-171).

Defending champion Smylie Kaufman is currently T46 after rounds of 71-67. He is seeking to join Jim Furyk (1998-99) as the only players to win back-to-back at the Shriners Hospitals for Children Open.

With his win at the Sanderson Farms Championship, Cody Gribble became the 13th left-handed winner on the PGA TOUR and the youngest left-handed player to win since Phil Mickelson won the 1996 AT&T Byron Nelson. Gribble is currently T46 after a second-round 5-under 66.

Dating to 2010, Las Vegas native Scott Piercy has the most birdies by any player at the Shriners Hospital for Open:

Player Total birdies since 2010 (through round two)
Scott Piercy 123
Nick Watney 116
Jason Bohn 116
Chad Campbell 112

Stuart Appleby withdrew before round two with a back injury.
