Mr. 57 lowered again.

Christobal Del Solar, a 31-year-old Chilean, who was birding in the eight-hole range, shot seven holes at Osprey Cove (North Cours) of Toronto, TPC Toronto, in Caliton, Ontario, to share the lead with Thorbjorn Olesen after the first round of the 2025 RBC Canadian open.

Last year, Del Solar set a PGA Tour record with 57-under 57 in the first round of the Astara Golf Championship at Korn Ferry Tour.

This time, he used a route that all-night rain reduction that stretched into the morning and forced the tour to allow for the first choice lie. Del Solar did the bird birds with the first and three consecutive pars, and he seriously started his bird festival. Few do better than he did on the 227-yard third shot seventh. Del Solar stuffed a long iron into it and kicked the bird. He fell on 3-11-11-11-34-foot bird^Th And wedge 10 inches at 12 o'clock^Th.

The 59 watch is fully effective as he reaches 9 holes in 14 holes and catches double digits on 16 birdies. But he hit 17 times, missing a 10-foot par putt and ended up failing to convert his 15-foot birdie putt. Still, it was the start of the rookie, who had two top ten in 10 games of the season and ranked 117th week in the FedEx Cup.

"I just hit the ball very well, it's simple and straightforward," he said.

Olesen, 35-year-old Dane and nine-time champion on the DP World Tour, believes his outstanding performance is his lowest round on the tour. He got over 5½ strokes on the green and ranked first in the stroke: putters. He canned a 34-foot putter in the first hole of the day and did not hurt.

"Don't think I've really missed any putters," he said. "I must have hit something very long, too. It's nice to see everything come in."

Olesen won the qualifiers in the 36-hole final at the Toronto Open on Monday, thanks to a birdie putt on his last hole and extended into Thursday.

"I spent a lot of money from the last putt," he said. "I didn't really have that good day. I felt like I was doing very well, but like the putt you knew you had to do, it can give you a lot of faith in yourself. Yes, I'm going to take it away for sure."

Del Solar and Olesen weren't the only ones to be low in the afternoon wave. Cameron Champ did not enter the field until he withdrew from Sahith Theegala on Wednesday, shooting a Wuji 62 with four birdies on each side. Jake Knapp fired 59 earlier this season, thanks to three birdies in the last four holes.
