It did not start. The match before it (Gicquel-Darcis) is currently in the 3rd set and match suspended because of rain. I'm sure the Montanes match is past the time most books had it to start, so maybe that's why your book no longer has it.
I also took Starace over Melzer in Austria (match just started), although a smaller bet. Starace has been good to me this tournament, so I played him to beat the home crowd favorite
