Whitlock set to face Suljovic in first semi-final at 2021 Gibraltar Darts Trophy
Both though were not at their best with Whitlock first through with a 6-4 win over Brendan Dolan, this was despite only averaging 83.4.
It was his doubling that was the impressive part of his game with Dolan missing 4/20 and Whitlock pinning 6/15 throughout the tie.
While for Suljovic, he ended the title defence of Krzysztof Ratajski, the 2019 winner with a 6-2 victory despite only averaging 86.51.
But both have shown this weekend that the form is there so they will hope to catch light at the right time in the semi-finals at Europa Point.
