Shanghai Open Tennis
Top seed and defending champion Roger Federer battled past in-form Russian Daniil Medvedev 6-4 4-6 6-4 to reach the last-16 at the Shanghai Masters.
Federer broke Medvedev twice to take the opening set.
Fresh off the biggest title of his career in Tokyo, Medvedev saved a break point early in the second set and that gave him momentum to grab a break of his own to force a decider.
Both players failed to take their opportunities to take an early lead in the final set before two unforced errors from Medvedev handed Federer a break in the ninth game.
