Stanislas Wawrinka secured his place in the semifinal of the Chennai Open, racking up his 300th career victory in the process.
The number one seed became the fourth Swiss player in history to achieve the feat, which came in a comfortable 6-2 6-1 win against Aljaz Bedene at the ATP 250 hard-court event.
Wawrinka required little over an hour to triumph over the Slovenian, collecting seven breaks of serve along the way on Friday.
The 28-year-old said: "Someone told me before I came to Chennai that I could achieve the milestone this week.
"It is special, after a long time on the tour, and I am really happy. I was focused on the match, which was not easy."
The 2011 champion now moves on to a final-four showdown with Canadian Vasek Pospisil.
The fifth seed reached an ATP World Tour semi-final for the fourth time in his career by brushing aside Indian wildcard Yuki Bhambri 6-3 6-3.
Pospisil, who climbed almost 100 places in the rankings to 32 last season, hit a series of powerful and measured groundstrokes to complete the win in just one hour and nine minutes.
On the other half of the draw, sixth seed Marcel Granollers came through a marathon encounter with Frenchman Benoit Paire 6-2 3-6 7-6 (7-5), in a match lasting two hours and 13 minutes.
The Spaniard appeared to be heading for defeat in the quarter-final tie, after a double-break in the third set left the fifth seed 5-1 ahead.
But Paire surrendered his serve three times in a row, and Granollers held his nerve in a tight tie-break to set up a semi-final match with another Frenchman in the final four in the shape of Edouard Roger-Vasselin.
The seventh seed survived a second-set scare to oust Israel's Dudi Sela 7-5 6-7 (6-8) 6-0.
