Top-seeded James Blake reached the second round of the Delray Beach International with a 7-5, 7-5 win over Robert Kendrick on Wednesday.
The 12th-ranked Blake had his the first set interrupted by rain and was down 2-3 and 3-4 in the second set.
"I was sweating a little bit when he was up a break twice in the second set," Blake said. "It was a tricky match, I was sitting around all day and there wasn't a lot of rhythm." Donald Young fell apart after leading 5-0 in the first set and eventually lost to Amer Delic 7-6 (7), 6-3.
The 18-year-old Young, who served for the opening set at 5-1 and 5-3, had two set points on Delic's serve in the 10th game, then watched four set points go by the wayside in the tiebreaker. After losing the first set, he tossed his racket out of the stadium. "I'm still trying to figure it out myself," said Young, when asked how he lost control of the match. "I've beaten him before and it shouldn't have gone to the tiebreaker in that first set. It did, he won it and all credit to him."
Delic, who won the opening set with a crisp backhand crosscourt winner, missed the racket throw, but sensed that Young's emotions were taking over.
"He did unravel," said Delic, who had received a warning himself early in the match for hitting a ball outside the stadium. "After the first set, he chucked his racket but I didn't see it. But I heard the boos from the crowd."
Young started the second set with a 2-1 lead after breaking Delic's serve in the third game, but couldn't keep his composure. ATP supervisor Mark Darby said Young, who received a code violation warning for tossing his racket, could be in further trouble for the match, which will be reviewed.
