Sunday's Men's Singles final at the ITF Masters Series event is an enticing contest between second seed Robin Ammerlaan (NED) and fourth seed Shingo Kunieda (JPN).
Ammerlaan was presented with a simlar task to Wagner after losing the first set of his semi-final against third seed Satoshi Saida (JPN) 26. However, the World No 2 asserted late on in the second set and eventually ended prospects of an all-Japanese final as he defeated Saida 26 75 62.
Meanwhlle, Kunieda had a decidedly more comfortable pathway to Sunday's final, defeating Tadeusz Kruszelnicki (POL) 60 63 in the other semi-final.

Injury ruled Gravellier out of her semi-final against Korie Homan (NED), giving Homan passage into an all-Dutch final against defending champion and World No 1 Esther Vergeer. Vergeer had one of her more challenging recent matches, but still came through her semi-final against compatriot Sharon Walraven for a comfortable 64 62 win.
