There was a recent article that I just read that tells how Matt Kemp put his full effort forward. The news explains how Kemp tried his absolute hardest during the game and, in the process, collided into the outfield wall.
This reminds me of an inspirational quote that I hear in the past:
“Effort is the best indicator of interest”
I greatly respect, how Kemp refused to walk off the field although he was obviously too injured to continue. Baseball means a lot to Kemp, so he is willing to put forward his “Maximum Effort”.
