Philippoussis, Chang Move to Second Round 　　Mark Philippoussis and Michael Chang beat their opponents in three sets respectively Monday, advancing to the second round of the Eurocard Open in Stuttgart, Germany. 　　Philippoussis, who injured his knee in a quarterfinal match against Pete Sampras in Wimbledon in July, beat Gianluca Pozzi 6-4, 4-6, 7-5. While Chang edged Rainer Schuettler 3-6, 7-6 (7-4), 6-2 in another match. 　　Philippoussis tried to come back in August, losing in the first round in Indianapolis, and did not play again until earlier this month. 　　The Australian will meet top-ranked American Andre Agassi in the next round. 　　Agassi and all other seeded players had a bye into the second round. Apart from Sampras, Patrick Rafter and Carlos Moya, who are injured, all other top ranked players are at the tournament, one of the so-called Super 9 series. SportsNews 1999-10-27 Page8
