How should I take this?!?

So I go workout at Crossfit and this guy starts talking to me after being introduced by a friend... As I was getting ready to workout he asked me if he could tag team his workout on the rower.. I said yes of course.. Then I was busting his chops because he likes a different baseball team than I do. So we were kidding about it and he was walking around the box and he stuck his tongue joking around (this guy is a couple of years older but is a very humble and genuine guy. He was joking around).. Then one day I was at a table reading over my workout and he comes and stands right behind me and doesn't say a word. He must of stood there for about a minute until I turned around and bumped into him. We laugh but said nothing. This past weekend a group of Crossfiters were at a party and he walked to the table were I was talking to some friends and I looked at him he goes HEY! Sits down and joins in on the conversation.. I don't remember what we were talking about but it must of been about relationships. So he quietly said he was single.

Does this mean anything or should I take as a friendship
How should I take this?!?
