Nicolai Budkov Kjaer faces hard-serving Reilly Opelka in round one of the Australian Open. The winner will be up against either 14th seed Alejandro Davidovich Fokina or unseeded Filip Misolic in round two. Time for our match prediction.

Kjaer is playing in only his second Grand Slam tournament. The other was on the grass of Wimbledon last year when losing in the second qualifying round  He is making his debut in this outdoor hard court Grand Slam and won his three qualifiers in just over six hours with two sets dropped.

The 19-year-old began 2026 with a loss to eventual champion Alexander Blockx in round one of the Canberra Challenger tournament. He's currently 135th in the live rankings, three below his career-high.

He's 72 places below Reilly Opelka in the live list. The American hasn't suffered a first round defeat in this Grand Slam since 2020. His best performance was a third round in 2022 but was  beaten in round two last year.

Opelka has played seven tie-breaks in his last five Australian Open matches so a side bet on sets going the distance could make a profit. Both of the tournaments he's played this year saw him beaten in the second round.

We tip Opelka to win this match.
