During spring training in 2018 he ran the Major League Baseball Players Association free agent camp.

Porter was raised in Newark, New Jersey in the South Ward and is a graduate of Weequahic High School.

He was granted free agency following the 2001 season, and he played the remainder of his career in the Atlanta Braves and Colorado Rockies minor league systems.

Porter was hired by the Washington Nationals on November 2, 2010, as their new third base coach, taking over from Pat Listach,[10] and took himself out of consideration for the Pittsburgh managerial job when he accepted his position with the Nats before the Pirates finished their interview process.

Chicago bench coach Jamie Quirk was yelling, apparently at Porter, from inside the Cubs dugout, causing Porter to leave his position in the third base coach's box and approach the third-base dugout to confront Quirk.

Porter was chosen over fellow candidates Tony DeFrancesco, Dave Martinez, and Tim Bogar.

One notable annoyance came with the team bringing Mark Appel (the top pick of the previous MLB draft by Houston) to throw a July bullpen session in Houston in the presence of the team pitching coach Brent Strom, which raised objections from Astro players due to perceived special treatment and objections from Porter due to not being notified of the session before it happened.

[17] Porter was replaced on an interim basis by Tom Lawless, who managed the final 24 games of the year that resulted in Houston finishing in fourth place in the division, their first non-last place finish in four years with the help of fresh players such as Dallas Keuchel and Chris Carter.

[23] Porter had approximately one week to assemble a staff, find a baseball facility for the camp, and secure temporary housing for the players attending it.

[22] Porter's coaching staff included former MLB players Chris Chambliss, Tom Gordon, Brian Jordan, Reid Nichols, Dave Winfield,[21] and Dmitri Young.

[26] Porter is from Newark, New Jersey, but has lived in Houston, Texas, since 1996,[14] and founded and is CEO of Future All-Stars Sports Development Academy since 1998.
