Two big guys in action on Day 2 at Roland Garros.
Juan Martin Del Potro appeared to be back to full strength about a month ago, but he had to take some time off to heal from another injury, possibly resulting from playing too much.
Karlovic is a big server, but clay isn't his best surface. If nothing else, this match should provide for some excellent shotmaking and interesting points.
Look for Del Potro to get by in this one in 3 entertaining sets.
