Tommy Haas: Through after Igor Sijsling suffered an ankle injury
Tommy Haas will have been a relieved man as he reached the second round of the Delray Beach International Tennis Championships.
The second seed's clash with Igor Sijsling was finely poised at a set apiece when the Dutchman was forced to withdraw with an ankle injury.
Haas had levelled the match at 5-7 6-4 but Sijsling was unable to continue after suffering a heavy fall during the second set.
Top seed John Isner was also given plenty to think about before he finally saw off the challenge of Jesse Levine 7-6 (7-3) 5-7 6-4.
Joining Isner and Haas in the second round will be Kevin Anderson after the sixth seed brushed aside Tim Smyczek 6-3 6-4.
However fellow seed Kei Nishikori is out after the No 4-ranked player suffered an injury in the first set of his match against Ivo Karlovic.
Former champion Ernests Gulbis needed just 73 minutes to beat James Blake 6-1 6-4, while Ricardas Berankis overcame Bjoern Phau 6-1 7-6 (7-4).
Daniel Munoz, Go Soeda and Denis Istomin all came through three-set epics to progress. Munoz edged out Ryan Harrison 6-2 1-6 6-3, Soeda held his nerve to see off Marinko Matosevic 2-6 6-4 7-6 (7-6) and Istomin came out on top 6-7 (7-3) 6-4 7-5 Benjamin Becker.
Lu Yen-Hsun booked his place with a 6-3 7-5 win over Bobby Reynolds, Jack Sock beat Matthew Ebden 6-3 6-3 and Edouard Roger-Vasselin was a 6-1 6-4 victor against Flavio Cipolla.
