Ernest Gulbis vs Victor Estrella prediction

Both players have poor and inconsistent result lately; they only won twice on their last 10 matches played. Ernest Gulbis even getting his rank down until #589 today. However I consider Ernest Gulbis are a better player on grass surface, his record was 15/21 on grass, these record still better than Victor Estrella's had with 5/15 form. This is logic choice and I count Gulbis has 55% chance to win here, and I believe Gulbis will use this opportunity to back to his track; so I back him to win today.
