Although the 37-year-old lost narrowly after taking a lead of two sets to one, he would have gained plenty of confidence from his performance.Kohlschreiber made an assured start to his Hamburg Open campaign, beating Jaume Munar in straight sets on Monday. Kohlschreiber was broken just once in the match, which he went on to win 7-6(5), 6-4.The German was a semifinalist at Hamburg in 2014 and 2017, and he would be fancying his chances of making a deep run this year too.Filip Krajinovic vs Philipp Kohlschreiber head-to-headFilip Krajinovic and Philipp Kohlschreiber have not faced off on tour before, so their head-to-head is currently tied at 0-0.Filip Krajinovic vs Philipp Kohlschreiber predictionPhilipp Kohlschreiber has won six out of his eight titles on clayJust like his compatriot Novak Djokovic, Filip Krajinovic likes to operate from the baseline and deploy a conservative style of play. Krajinovic's solid groundstrokes, particularly the double-handed backhand, are his biggest strengths. The Serb is not a huge server, but he can hold his own in the rallies with his deep and consistent shots.Philipp Kohlschreiber, on his part, can generate impressive power from the baseline. The German can strike winners at will off both his forehand and backhand, something that is particularly useful on clay.Kohlschreiber might be at the advanced stage of his career, but his reflexes remain sharp. He has had an extra day of rest too, which might work in his favor on Wednesday.All things considered - especially his recent form - Kohlschreiber might have an edge in this match.Prediction: Philipp Kohlschreiber to win in three sets.
