Robert Blair and Gabby White won the title in Mulheim
Robert Blair earned some compensation for having to retire in the mixed doubles final of last season's German Open by winning it this time around.
The Scot, who partnered Imogen Bankier last year, and England's Gabby White defeated Japan's Shintaro Ikeda and Reiko Shiota 16-21 21-16 21-15.
Their win in Mulheim was ideal preparation for the sixth seeds ahead of the All England Championships.
Blair and White defeated Bankier and Chris Adcock in the semi-finals.
That 21-17 21-17 victory over the Anglo-Scottish pair ranked 43 in the world, as well as a quarter-final win over number 25 duo Alexandr Nikolaenko and Valeria Sorokina, is expected to boost their own ranking further.
Blair, who retired in the first game of last season's German Open final with a back injury, and White are currently ranked 55 as they head for Birmingham.
They take on Thailand's Patipat Chalardchaleam and Saitree Amitapai in the first round on Wednesday.
Blair and White recently beat the Thai duo in the Malaysian Open first round in three close games.
Seventh seeds Adcock and Bankier are also heading for Birmingham boosted by a quarter-final win over Koreans Lee Yong Dae and Kim Ha Na.
Adcock and Bankier will face Ikeda and Shiota for the first time in the opening round on Wednesday.
