MUNICH (AP) — Top-seeded Alexander Zverev will play for a record-equalling third ATP Munich title after reaching the final on Saturday. The German riding home crowd support will face second-seeded Ben Shelton in Sunday's decider at the BMW Open.

Zverev, playing Tallon Griekspoor, was heckled while serving at 5-5 in the second set when the supporter yelled: “Let’s go, you… wifebeater!” The top-seed won the game but during the changeover spoke to chair umpire Fergus Murphy.

World number three Alexander Zverev fired nine aces en route to toppling Hungary's Fabian Marozsan 7-6(3) 6-3 on Saturday to set up a Munich Open final showdown with American Ben Shelton.
