Rio Grande, Puerto Rico (My Sportsbook) - The first round of the Puerto Rico Open was washed out Thursday by another round of heavy rain that left the Trump International course unplayable.

Only 18 players in a full PGA Tour field teed off before play was suspended at 7:19 a.m. local time. After a six-hour delay, the decision was made to postpone the round for the day.

It will resume Friday morning at 7:15 a.m. (6:15 a.m. ET) with preferred lies in effect.

The PGA Tour said that six inches of rain had fallen by 2 p.m. local time. Five inches of precipitation fell on the club last weekend and it received nearly a half-inch earlier this week.

Skip Kendall was one of only nine players to finish a hole before the weather stoppage. Kendall eagled the par-four 10th, holing a seven-iron from 159 yards to take the early lead at two-under.

It was the only hole Kendall played. He couldn't see the ball go in because the rain storms made it too dark.

Germany's Alex Cejka birdied No. 1 and five players made par on their only hole. Harrison Frazar was the only player to finish two holes and he was one- over par.

Michael Bradley is the defending champion after he held off Brett Quigley and Jason Day last year for his third PGA Tour victory.

Only three of the top 100 players in the world rankings are in Puerto Rico. Most of the best players are competing in the WGC-CA Championship in Florida.

NOTES: Friday will mark the fifth time this season that a tournament will feature preferred lies...It was the first time in the Puerto Rico Open's three-year history that there was a weather suspension.
