Match between two guys who are known for their tempers, and known to get crazy in matches and have meltdowns, particularly Haase. Melzer has a 2-0 H2H, both wins in three sets on clay. Melzer has two first round losses after winning the Memphis title in mid-February. Haase defeated Matosevic in straight sets on Wednesday to make it to the second round. Melzer has a 4-8 record in Miami in his career, and I think that run of poor form at this event continues. I'm going with Haase in straights.
