Jon Rahm became one of the early movers up the Fort Worth Invitational leaderboard on Saturday, posting a 6-under 64 to climb up to 8-under for the tournament.
As Rahm met with reporters, leader Justin Rose had just opened his round with three consecutive birdies.
"Hopefully Justin stops making putts," Rahm said, smiling. "Stops making birdies and gives the rest of us a chance tomorrow."

Rose didn’t get the memo. He did what the No. 5-ranked player in the world should do with a lead going into the weekend – he extended it.
Rose started the day at 10-under, one stroke better than playing partner Emiliano Grillo (9-under), and got off to a fast start.
As stated, the 37-year-old Englishman made three straight birdies and another on No. 6. Another birdie on No. 11 pushed him to 15-under for the tournament, although he gave a stroke back with a bogey on the par-3 16th.
But that proved to be Rose’s only bogey on the day and he finds himself in great shape to earn his first win of 2018 on Sunday. He is at 14-under and with a four stroke lead over Brooks Koepka and Grillo.
"I've won and lost actually from four ahead, so I've got experience both ways," said Rose, who last played this event in 2010. "Just shows you can't get ahead of yourself. It is a big lead, but it isn't big enough. It's not big enough to be counting the holes away."
Rose admitted the key to getting a plaid jacket will be finding the right balance between playing smart and staying aggressive.
Oh, and staying hydrated throughout the day. Temperatures were in the high-90s on Saturday, and Rose admitted it affected him somewhat on the back nine.
Similar forecasts are called for Sunday.
"[My caddie Mark Fulcher] has done a great job of just literally handing me water bottle after water bottle. It seems relentless," Rose said.
He smiled and then said: "To be honest with you, I haven't even seen the inside of a restroom yet, so you can't even drink quick enough out there.
"It was a factor today for sure. It's as hot tomorrow, so recovery tonight is a big focus."
Rose should feel good about his chances, of course, but Colonial winners have come back from bigger deficits.
The biggest deficit a winner has overcome is seven when Nick Price won the 1994 event. He fired a 6-under 64 in the final round and defeated 54-hole leader Scott Simpson in a playoff.
The most recent winner to come back from at least four shots is in 2001 when Sergio Garcia won his first PGA Tour event. Garcia overcame a five-stroke deficit with a 7-under 63 on Sunday, as 54-hole leader Phil Mickelson posted an even-par 70.
Koepka, ranked No. 11 in the world, appears to Rose's biggest challenger and will be playing with him in the final group with the tee time set for 1:05 p.m. The 2018 Colonial could become a showdown between two U.S. Open champions -- Koepka won last year's, Rose in 2013.
"Got to get off to a good start here," said Koepka, who is making his first appearance at this event. "If you can birdie the first two, at least, put some pressure on Rosey, you'll be just fine.
"Playing really well and I'm pleased with where I'm at."
