Winners on the weekend in Doha and Chennai, Jo-Wilfried Tsonga and Milos Raonic lost their opening matches Wednesday at the invitational Kooyong Classic, a warmup for next week's Australian Open.
Tsonga, who won the Qatar Open in an all-French final Saturday against Gael Monfils, lost 6-4, 6-3 to Austria's Jurgen Melzer as cold, blustery conditions made it difficult for players.
Raonic, who didn't drop a service game en route to winning the Chennai title, lost 6-1, 6-2 to Mardy Fish, who had some mixed performances as part of the U.S. team at the Hopman Cup last week.
''It's been a long time since I've really felt 100 percent healthy, which I do now,'' said Fish, who finished in the top 10 for the first time last season. ''And now I just need the matches and I need to get going again.''
Raonic withdrew from the eight-man tournament after the loss, citing an upset stomach.
Australian teenager Bernard Tomic beat No. 7-ranked Tomas Berdych 4-6, 6-3, 6-4 and Monfils finished off the day with a 7-6 (2), 7-6 (3) win over American veteran Andy Roddick.
Monfils hit a between-the-legs forehand to seal the opening tiebreaker after earning four set points with a full-stretch backhand crosscourt winner that caught Roddick by surprise.
After a close second set, the deciding tiebreaker was lopsided with Monfils earning four match points on a Roddick backhand error. Roddick saved one before Monfils put away the match with a crisp volley.
