It will be an all-Spanish affair in the Winston-Salem Open final after Pablo Carreno Busta and Roberto Bautista Agut won their respective semi-finals on Friday.

Carreno Busta won through in straight sets but he was made to fight by Australian John Millman at the ATP 250 event. 

After claiming the first set in 35 minutes, it took one hour and 13 minutes for the second to be decided. 

Millman provided a tough test for the Spaniard, but fell short in the tie-break as Carreno Busta claimed a 6-4 7-6 (7-5).

The world number 49 will now face compatriot Bautista Agut in the decider after the latter moved past Viktor Troicki. 

Bautista Agut needed three sets to get past the Serbian in two hours, 10 minutes. 

However, he could have wrapped it up much earlier, having led 5-0 in the second set before Troicki made his way back into the contest. 

After taking out the second set, Troicki was unable to repeat his heroics in the third, with Bautista Agut finishing strongly for a 7-5 6-7 (2-7) 6-2 win. 

The result guarantees a third different Spaniard to win the tournament after Fernando Verdasco (2009) and Carlos Moya (1997).
