Nicolai Budkov Kjaer Faces Reilly Opelka in ATP Madrid 2026 First Round

On Thursday, April 23, 2026, Norwegian qualifier Nicolai Budkov Kjaer will take on American veteran Reilly Opelka in the first round of the ATP 1000 Mutua Madrid Open. The match is scheduled to begin at 6:30 p.m. Local time (12:30 p.m. UTC) on Stadium 3 at the Caja Mágica in Madrid, Spain, according to the official tournament schedule confirmed by L’Équipe and verified through multiple sports sources.

Budkov Kjaer, ranked 140th in the ATP rankings entering the tournament, earned his main-draw spot through qualifying. Opelka, the 70th-ranked player in the world, brings significant experience to the clay courts of Madrid, having reached the fourth round here in 2023. Their only previous meeting came at the Australian Open earlier in 2026, where Opelka prevailed in straight sets.

This clash represents a classic David versus Goliath scenario on the red clay. Budkov Kjaer, at 19 years old and 1.91 meters tall, represents the next generation of Norwegian tennis following in the footsteps of Casper Ruud. Opelka, at 28 years old and an imposing 2.11 meters, uses his powerful serve and aggressive baseline game to dominate opponents, particularly on faster surfaces.

The Norwegian has shown promise on the Challenger circuit this season, reaching the final in Thionville, France, where he lost to Oscar Otte in a tight three-set battle. His qualifying run in Madrid included victories over local Spanish players, demonstrating his ability to handle the pressure of performing in front of a home crowd.

Opelka comes into the match after a solid start to his clay court season, with victories in Barcelona and Miami. His serve remains one of the most formidable weapons in tennis, regularly exceeding 220 km/h and producing numerous aces per match. However, his movement on clay has historically been a function in progress, which could provide an opening for the younger, more agile Budkov Kjaer.

Tennis analysts note that the key to this match will be Budkov Kjaer’s ability to extend rallies and force Opelka into uncomfortable positions on the baseline. The Norwegian’s two-handed backhand and willingness to come to the net could disrupt Opelka’s rhythm, particularly if he can neutralize the American’s serve early in points.

For Opelka, the strategy will likely involve using his serve to win quick points and minimize extended exchanges where Budkov Kjaer’s consistency could grow problematic. The American will require to maintain his focus throughout the match, as lapses in concentration have occasionally plagued him during longer contests.

The head-to-head record shows Opelka leading 1-0, having won their only previous encounter at the Australian Open in January 2026 with a 6-4, 6-3, 6-4 victory. That match took place on hard courts, making this clay court encounter a significantly different challenge for both players.

Weather conditions in Madrid for the match are expected to be favorable for tennis, with temperatures in the mid-20s Celsius and light winds. The clay courts at the Caja Mágica are known for their slower pace compared to other European clay venues, which could further benefit Budkov Kjaer’s defensive capabilities.

A victory for Budkov Kjaer would represent one of the biggest upsets of the tournament so far and significantly boost his confidence and ranking prospects. For Opelka, advancing past the first round is crucial as he looks to build momentum for the upcoming French Open, where he aims to improve upon his previous best showing.
