After looking at this year's Wimbledon really a so far I think it's safe to say that we're bound to get some change in the "top" of men's tennis. Now whilst this change can come from anyone there are a few people I can see breaking through faster than others. Jerzy Janowicz for example is my number one pick to be the first major break through as he has the service skills of some of the best in the game like Raonic, whilst also being able to hammer ground strokes on the court. I think if he gets some more confidence and a little more consistency he'll be top 5 by the end of the year. Vasek Pospisil is also someone I see making a nice run this summer. I feel he is the actual future for Canadian tennis. He may be a mental case right now however I've seen him live actually and have found that he has a ton of desire. He was also only two holds away from entering the third round of wimbledon. Bautista Agut- I've had my eye on him ever since I watched him at a Challenger event back in Novemberish I believe. He has fire and a good head on him. Plus he beats everyone he's supposed to beat. Give him time and he will shine. However who do you all think can be the next big thing.
