Players interact with the fans in some very subtle ways.
Here is another story. My son and I, when he graduated from high school in 2009, took a trip out to California.
The Orioles were out on the west coast so we bought tickets to see them play the Angels on Saturday, July 4th and Sunday, July 5th (which is my son's birthday). For the July 5th game, we had field level seats down the RF line. The crowd was on the lighter side that day so there were plenty of empty seats around us.
My son was wearing an Orioles shirt and cap. Early in the game there was a final out to an Angels inning with a fly ball to the right fielder. I can't remember who the right fielder was but I'm thinking it was probably Markakis. After the catch we stood up, hoping that maybe he would toss the ball our way. It became apparent that he was eyeballing us and was moving in our general direction. We were maybe about 15-20 rows up, so it wasn't an easy toss. Sure enough, here comes the ball, on a perfect throw, right to us. What a birthday gift for my son!
There were several other fly outs to right field to end an Angels inning that day and every ball was sent in our direction. We ended up with about five baseball's that day.
Also, right before the game started, Orioles manager, Dave Trembley was in the stands near the Orioles dugout talking with some people. It was getting close to game time and he began to move towards the dugout. We happened to be standing about 10-15 feet away. He casually looked in our direction, no doubt aware that we were Orioles fans because of what my son was wearing. He looked at us and acknowledged us by giving a simple nod of his head and took a ball out of his back pocket and tossed it to my son. It was such a subtle gesture of acknowledgement and one I will never forget.
