Fritz fights through to reach Toronto Masters quarters, Tauson stuns Swiatek as Osaka sails

Taylor Fritz battled into Monday morning before finally getting past Czech Jiri Lehecka with a 7-6 (7/4), 6-7 (5/7), 7-6 (7/5) victory in three hours to reach the quarterfinals of the ATP Toronto Masters.

The US second seed finished off a complete matched set of Masters 1000 quarterfinals as the last piece of the puzzle fell into place in Canada.

The late-night marathon lasted 39 games without a break of serve, with 15 aggregate break points going begging.

Fritz delivered two aces in the final-set tiebreaker on his way to the narrow win, moving into the last eight as Lehecka drove long.

Fellow American Ben Shelton earned a second chance after Flavio Cobillo failed to serve out their match, with the fourth seed finally securing a somewhat contentious 6-4, 4-6, 7-6 (7/1) win.

The pair had words after the match, which Shelton characterised as nothing serious.

The winner, who now plays Alex de Minaur, earned his 100th ATP-level win after nearly two and a half hours, firing an ace on his second match point to wrap up a place in the last eight for a third straight tournament after Wimbledon and Washington.

De Minaur pushed his ATP winning streak to seven matches as he fended off Frances Tiafoe 6-2, 4-6, 6-4,.
