The steady drizzle that fell Friday morning almost made Augusta National Golf Club unplayable, several players said after completing their second round.

By the end of the day, heavy rains had made sure the second round of the Masters would not be completed Friday. Thirty-eight players will come back to finish their round at 7:45 a.m. today.

The course was already wet from rain earlier this week, and the conditions worsened as rain fell throughout the morning. Masters officials did not stop play until late afternoon, when the rain forced players and patrons to scramble for shelter.

The players who teed off early complained they were at a disadvantage because of all the rain.

"If the course would have been dry, I really think I could have shot 3- or 4-under," said Fred Couples, who won the Masters in 1992. "I did get upset because the course was under water."

When Couples reached the fifth green, he said workers were clearing water off the green just 5 feet from the pin.

"I was screaming my head off," he said. "Well, not really screaming, but talking louder to the officials. I apologized. I don't think they dropped the ball on it, but I had never seen that before here. Every shot was almost a casual water shot."

According to the Rules of Golf, players are allowed to drop a ball if it is considered to be in casual water. The benchmark for determining that is to step on the ground in question and see whether any water rises above the heel mark of the shoe.

In certain cases, tournament officials can allow players to lift, clean and place their ball. That's a considerable advantage over hitting a ball caked in mud, but Masters officials did not enact that Friday.

"The eighth fairway had a river running down it," Couples said. "I kept saying to the officials, 'What are we going to do?' Two holes later, it was fine."

Stewart Cink, who shot a 2-under 70 to get to even par through 36 holes, said he thought play should have been halted in the morning.

"When you have standing water on the green, that is above and beyond what we should do in a major championship," Cink said. "It was over the line, no question. This isn't a member-guest (tournament). My umbrella was gathering water at one point."

Cink's group held up play as he had to take a drop on the seventh fairway. Finding a suitable place to drop was a challenge, he said.

"I basically dropped my ball in mud," he said.

Billy Andrade teed off in the rain at 9:25 a.m.

"I don't think the golf course could have taken much more," Andrade said. "They said when we were on the third hole they were pretty close to calling it."
