Gstaad, Switzerland (SportsNetwork.com) -
Former top-10 star Gilles Simon came up a first-round loser Tuesday at the Swiss Open tennis event.
Spaniard Pablo Andujar was leading the sixth-seeded one-time world No. 6 Simon 6-2, 3-2 when the Frenchman retired due to an illness on the red clay at Roy Emerson Arena.
Meanwhile, seventh-seeded Dutchman Robin Haase avoided an upset by outlasting Kazakhstan's Aleksandr Nedovyesov, 6-4, 6-7 (3-7), 6-3, on Day 2. Haase was last year's Gstaad runner-up to this week's top seed, Russian Mikhail Youzhny.
