U.S. Open | Carballes Baena hands Rune shock first-round exit

Spain's Roberto Carballes Baena battled past an error-riddled Holger Rune 6-3 4-6 6-3 6-2 in the first round of the U.S. Open on Monday, handing the fourth seed a shock early exit from the year's final major.

Carballes Baena was lethal from the baseline and fired off seven aces as his Danish rival struggled to make any form of impact on a muggy afternoon match at Flushing Meadows.
