Sampras supreme on way to final

Tennis

Pete Sampras stretched his unbeaten run to 21 matches with a 6-3, 6- 4 victory over the unseeded Dutchman Jan Siemerink in the Stuttgart Open semi-finals yesterday. The triple Wimbledon champion, who has won his last three tournaments, including the US Open, and is unbeaten indoors this year, took 79 minutes to clinch his place in today's final of the $2.2m indoor event. The winning streak is the second longest of his career. In 1994 the 25-year-old American won 29 consecutive matches. Sampras made a key break of serve in the sixth game to lead 4-2 before taking the first set in 32 minutes. Although he dropped his serve at the start of the second set, he bounced back with breaks in the third and seventh games. Sampras will meet Boris Becker in the final after the German proved he was back to his best after a serious wrist injury with a 6-4, 6-3 victory over Michael Chang.
