Gilles Muller, Anett Kontaveit pick up Ricoh Open titles
Neither player was able to force a break of serve in the match but 34-year-old Muller had the edge over his 38-year-old opponent in both tie-breaks. He clinched victory by winning four successive points.
Muller said: "I think we should make a suggestion to the ATP that we just start with the tie-break next time! It's always tough to play Ivo and I'm glad I could beat him."
Kontaveit built momentum after saving two break points in the third game of the match and eased through the first set.
She fell 3-1 down in the second but turned the tide by winning 10 successive points and did not look back.
