Bjorn Phau takes on compatriot Dominik Meffert for a place in the final of the Heilbronn Challenger.
Both these guys are experienced competitors at challenger level and although unseeded this week, they've both been in the finals of many of these events in the past so it's no surprise to see them in the last four.
Phau is a wily competitor who reached a career high of 59 back in 2006 and he saw off seventh seed Grega Zemlja 6-3, 6-4 in round one before taking advantage of a bit of a breakdown from Martin Klizan in the quarters, easing past the talented Slovak 6-0, 6-3.
Although ranked 171, such is the strength of this draw that Meffert actually had to come through three rounds of qualifying. It seems to have stood him in good stead as he's enjoyed some top notch results in the main draw. First he took out former world number 33 Andrey Golubev in straight sets, then outlasted veteran fourth seed Michael Russell before seeing off the big serving Rik De Voest 6-3, 6-4.
As for who's going to win this one, well the head-to-head stands at 2-0 to Phau who won 7-6(10), 6-4 when they met in Dortmund last summer but both those wins were on clay.
Indoors, look for Meffert to sneak through in three sets.
