Collin Morikawa earned his second career major title with a victory at the 2021 British Open.

Louis Oosthuizen had led The Open Championship after each of the first three rounds, but it was Morikawa who stormed ahead with a 66 in his final round Sunday to finish 15 strokes under par for the tournament.

Jordan Spieth finished two strokes back for second place at Royal St. George's, while Oosthuizen ended up in a tie for third.

It continues an incredible 12 months for Morikawa, who won the PGA Championship last August and now has three straight top-10 finishes at majors. He also joins some elite company in a variety of categories:

Tiger Woods is the only other player to win these two majors before the age of 25.

Oosthuizen was the favorite heading into the final day thanks to his one-stroke lead and consistent play over the first three rounds.

The fourth round wasn't quite as smooth for the South African, however, as he finished the front nine with two bogeys and no birdies. The par-five seventh hole was especially disappointing as Oosthuizen hit it from one bunker to the other before saving bogey.

It opened the door for others to move up the leaderboard, with Morikawa especially taking advantage.

The 24-year-old grabbed the solo lead and built a small cushion thanks to three straight birdies from No. 7 through No. 9, plus a clutch par save on No. 10.

It was still far from a runaway as Spieth also remained in the hunt thanks to impressive putting.

It effectively created a two-man race between the Americans over the final few holes, though Morikawa remained just ahead on the leaderboard.

Every time Spieth put the pressure on with a birdie, Morikawa stayed in front with key shots when needed. The clutch putting continually turned heads—not only on birdies but also on pars:

Morikawa only had one birdie on the back nine, but finishing bogey-free in the final round helped him seal the impressive victory.

Oosthuizen dropped to a tie for third, although he still turned heads with a near ace on No. 11:

Jon Rahm also had an incredible round to shoot 66, including an eagle on No. 7 and a late run of birdies to stay in the hunt:

Rahm finished in a tie for third place despite an opening round of 71.

Other notable players like Brooks Koepka and Dustin Johnson had a strong final round to end up in the top 10.

Though this was the final major of the year, these quality performances could help build momentum going forward with the FedEx Cup playoffs on the horizon.
