RIO GRANDE, Puerto Rico – Boo’s back.

Playing in his first PGA TOUR event since the 2017 RBC Canadian Open, Boo Weekley shot a 7-under-par 65 Saturday at the Puerto Rico Open to move into the top-15 early on Moving Day.

Weekley (72-73-65) was away from the PGA TOUR for nearly 18 months after being sidelined with tendinitis, which led to surgery.

During his comeback, doctors discovered cancer in his shoulder.

A second procedure to a remove a cyst kept him on the shelf until November 2018, when he finally started hitting balls again.

Weekley has played four of the first five events on the Web.com Tour in his return to action and told reporters at the LECOM Health Classic of his cancer diagnosis.

He got into the Puerto Rico Open on a Sponsor’s Exemption and has made the most of the opportunity so far.

The 45-year-old started his first round 4-over through five holes, but has righted the ship since then.

Weekley said he was nervous returning to the TOUR after being away for so long.

“I know I need to make this cut and just I put a lot of pressure on myself right out of the gate,” said Weekley. “Once I got kind of calmed down out there, I went back to playing golf.”

The three-time TOUR winner said Saturday’s round could have been even lower.

He missed short birdie putts on the par-4 3rd, the par-3 16th, and the par-4 17th. The winds that had been swirling around Coco Beach Golf Club the first two days had subsided through Saturday morning.

He said the key to his solid play of late has been to get straightened up at address. He sent a video to his coach last week who showed him some old videos and photos of his positioning and Weekley was able to make the adjustment.

“It was kind of like one of them days you could have really got after it, you know, but then again I'm happy with what I shot,” said Weekley. “You can't ever complain when you shoot under par anyway on any of these golf courses.”

Weekley admitted he wasn’t 100 percent yet, health-wise, but he’s aiming to feel that way in about three months.

“Once I get back to playing golf and still doing the same little regimen that I've been doing with my shoulder and my arm, elbow and stuff, I should be back to normal,” he explained.

Weekley isn’t sure what his schedule is going to look like for the balance of 2019 – he’s planning on playing mostly Web.com Tour events but will say ‘yes’ to any PGA TOUR opportunity that comes along – but one thing is for sure: he’s just happy to be back playing again.

“I feel like I can actually hit golf shots,” he said.
