For a long stretch, Marvin Seidel played the Yonex ASTROX 88 D PRO. The racket was built specifically for doubles and is mainly designed for pressure from the backcourt.
With its head-heavy balance and stiff shaft, it suits players who generate a lot of pace from the backcourt while also wanting a direct racket for fast follow-up actions. That mix is especially interesting in men's doubles, where attack and defence can switch within just a few shots.
