Antrim cue ace Mark Allen has paid tribute to Terry Griffiths after potting his first title of the season.
Allen, who works closely with the 1979 world champion, says his success at the Ruhr Open was due in no small part to the influence of the Welshman.
Allen was back to something approaching his best to clinch the crown by beating Ding Junhui 4-1 in the final in Germany.
The 27-year-old Allen outplayed China's Ding in the final of the season's fifth European Tour event to take the €25,000 (£21,000) top prize.
"The way my form has been over the last few months, it's a big achievement to win here," said Allen.
"A lot of it is down to Terry Griffiths. We did some work last week and he made a change on the technical side and helped me to be more positive.
"I need to keep putting the work in with him and hopefully it will pay dividends.
"I was able to have a couple of hours rest after my semi-final, whereas Ding had a long match, so maybe he was not as fresh as me for the final, though I'm sure he was just as motivated."
Left-hander Allen landed his first title since he won the Haikou World Open seven months ago.
Allen took the opening frame of the final with a break of 76. Ding looked set to level until he missed a red to a centre pocket on 55, and his opponent battled his way back into the frame and took it on the colours.
A superb run of 100 put Allen 3-0 ahead, before Ding pulled one back with runs of 40 and 32. But there was to be no fight back, as Allen's 74 in frame five saw him over the winning line.
