And now giant-killer Tennys stuns Thiem

Australian Open

Tennys Sandgren pulled off another upset at the Australian Open on Monday as he sent Dominic Thiem packing.

The American claimed a stunning victory over ninth seed Stan Wawrinka in the second round and then booked his place in the fourth round with a four-set win over Maximilian Marterer from Germany.

And he continued his great form in the last 16 as he stunned fifth seed Thiem 6-2, 4-6, 7-6 (7-4), 6-7 (7-9), 6-3 in a match that was just three minutes shy of four hours.

The 26-year-old, playing in his first Australian Open, had a match point in the fourth set, but Thiem fought back and took it to a fifth-set decider.

Sandgren, though, claimed the decisive break in the sixth game and then served out the match to reach the quarter-finals of a Grand Slam for the first time.

The world No 97 will face either Novak Djokovic or Hyeon Chung in the last eight, but he admits he feels like he is still in dreamland.
