Collin Morikawa left Bay Hill a year ago with an 80 on his scorecard and a second straight missed cut in the Arnold Palmer Invitational at Orlando, Fla. That wasn’t on the former Cal star’s mind when he arrived to this signature event because it was more about the state of his game than the golf course.

Bay Hill is tough as ever. Morikawa is starting to look more like the two-time major champion.

He made a 12-foot birdie putt on the 18th hole Saturday for a 5-under 67 that enabled him to take a one-shot lead over Russell Henley going into the final round.

“It’s a course that if you’re not playing great it’s going to show. It’s just one of those that you can’t fake it,” Morikawa said.

There was no faking it on a course that has been baked by three days of sun, increasing warmth and greens that are lightning quick. Morikawa missed a 5-foot par putt on the 14th hole for his only bogey in the last 45 holes.

That’s almost as impressive as his six birdies Saturday. And now he has 18 holes and a strong chasing pack to try to capture his first PGA Tour title in 17 months.

Shane Lowry, the 36-hole leader, shot a 76, leaving him six shots behind. Rory McIlroy made bogey on three of his last four holes for a 73 to fall seven shots behind. Scottie Scheffler shot a 71 to fall eight shots back.

Jason Day, who opened with a 76, put himself back in the mix with a tournament-low 64 on Friday and a wild round of 69 on Saturday.

Amateur one shot back at Puerto Rico Open >> South African amateur Kieron Van Wyk shot a 7-under 65 to pull within a stroke of leader Karl Vilips with one round left in the Puerto Rico Open.

The 23-year-old Van Wyk, a senior at the College of Charleston, is making his first PGA Tour start.

Takeda takes lead at LPGA tourney >> Rio Takeda of Japan shot a 3-under 69 to hold a two-shot lead after three rounds of the LPGA’s Blue Bay tournament on China’s southern island of Hainan.

No. 7 Alabama beats No. 1 Auburn at OT buzzer >> Mark Sears hit a game-winning floater as time expired, and No. 7 Alabama spoiled the home finale of rival and No. 1 Auburn with a 93-91 overtime road win.

The off-balance buzzer-beater from the free-throw line was only the third made basket of the game for Sears, who finished with nine points.

Alabama (24-7, 13-5 Southeastern Conference) got 23 points from Grant Nelson and 15 points each from Labaron Philon and Clifford Omoruyi.

The win ended a two-game losing skid for Alabama and handed a second straight loss for Auburn (27-4, 15-3).

Johni Broome scored 34 points, including a game-tying layup in the final minute of regulation and a game-tying 3-pointer with 15 seconds left in overtime.

Tennis

Djokovic stunned at Indian Wells >> Novak Djokovic was shocked by Botic Van De Zandschulp 6-2, 3-6, 6-1 in the second round of the BNP Paribas Open at Indian Wells, suffering an early exit at the hands of a tournament lucky loser for a second consecutive year.

Djokovic fell to lucky loser Luca Nardi of Italy last year, and history repeated itself on the Stadium One court a day after top-seeded Alexander Zverev also went out.

Tallon Griekspoor upset Zverev 4-6, 7-6 (5), 7-6 (4) on Friday.

The loss came eight days after Zverev also was the top seed when he was upset by American teenager Learner Tien 6-3, 6-4 in Acapulco, Mexico.

The Zverev-Griekspoor match lasted 3 hours, 7 minutes. Griekspoor collapsed on the court after converting his sixth match point for his first win over an opponent ranked in the top five.
