"Watch the other team's players, watch the game," he said.
Porter says players nowadays grew up in a "SportsCenter generation," meaning they were fed highlights of baseball games, but didn't always get to see the work that went into the success.
"When I was coming up, you literally had to watch the game to find out what happened," he said. "Now, you see a guy hit a home run, but they don't show you the 1-2 breaking ball he took, the 2-2 changeup he took to get himself to the 3-2 pitch to hit the home run."
Porter has urged players to pay more attention to the details in their pursuit of success.
"Watch the game in its entirety, see what's going on, and you'll be amazed how you can learn and not wait for someone else to teach it to you," he said.
