A resurgent Jason Day is fired up for the looming US Open and Masters having sniffed a second career major victory with a hot finish at the US PGA Championship.
The former world No.1 continued his return to form with a tie for fourth - three shots behind PGA champion Collin Morikawa - at San Francisco's TPC Harding Park to record his 10th top-five result in 38 major starts.
The 23-year-old Morikawa, playing just his second major, shot a 64 for a 13-under-par total and a two-stroke win from England veteran Paul Casey (66) and overnight leader Dustin Johnson (68).
Day, the 2015 PGA champion, carded a solid 66 to finish at 10 under alongside Matthew Wolff (65), Bryson DeChambeau (66), Tony Finau (66) and Scottie Scheffler (68).
Day posted three consecutive top-10s on the US PGA Tour leading into the PGA Championship and has clawed back up the world rankings to No.32.
The 32-year-old is champing at the bit to continue his bid for a second major, which he will do at September's US Open at Winged Foot in New York and the Masters at Augusta National in November.
"I can't wait to play these next two majors now," Day told AAP after his round.
"The US Open is the most testing major and I love that, but the Masters is my favourite event and one I really want to win. It's exciting."
Although no fans were in attendance, the PGA saw one of the most dramatic finishes to a major championship in recent memory.
A whopping seven players were tied for the lead late in the round before Morikawa chipped in for birdie at the 14th to break the stalemate.
A stunning eagle at the 16th set up a cruisy victory.
Day, made a late charge with a birdie at the 10th and a 40-foot birdie at the 11th before another at the 14th to post a share of the clubhouse lead.
But Morikawa took the first major of 2020 by the scruff of the neck.
"It was really cool to be able to be in contention again at a major on Sunday," Day told reporters.
"It's just nice to be able to know my game can handle the pressure of trying to win a major championship.
"There's still a lot more to improve on but if my putter gets hot, I'm going to win pretty soon.
"Everything is starting to connect and click."
Day's countryman Adam Scott signed off with a solid 68 to share 20th at four under, while fellow Queenslander Cameron Smith (70) finished at even-par.
