In 2008, Martinez agreed to be a special instructor for the Yankees to help their first basemen with defensive skills.

After Spring training, he was named Special Assistant to the General Manager.

Starting in Spring training 2010, Martinez became a color commentator for the YES Network, replacing the departed David Cone.

Prior to the 2004 Summer Olympics, the host nation, Greece, trying to build up their chances of winning a medal, decided to put together a team of North American baseball players of Greek heritage.
Martinez, having some Greek ancestry, was approached by the Greek Olympic team manager, Rob Derksen, and asked to play for the host nation.
Martinez, along with fellow MLB players Eric Karros and Aaron Miles, declined the offer because the games were in the midst of the Major League Baseball season.

Martinez was named the hitting coach for the Miami Marlins for the 2013 season, replacing Eduardo Pérez.
On July 28, 2013, Martinez resigned from the position amid allegations of physically abusing Derek Dietrich several months before the resignation.
Martinez's behavior in the clubhouse was reported to include verbal attacks towards the Marlins' Justin Ruggiano and Chris Valaika, along with minor league player Matt Downs.

Despite his credibility as a hitter, Martinez presided over the worst offense in Marlins history and as a result, the 2013 Miami Marlins were referred to as  one of the historically worst offensive efforts in Major League history.
