Davey Johnson may be the oldest manager in the majors at 69 years old (he turns 70 on Jan. 30), but he is no stranger to technology. The Nationals skipper said over the summer he frequently texts back and forth with his players. Some will even text him when they need a day off. Johnson's cell phone skills should come in handy as Major League Baseball has announced a deal with T-Mobile to bring them to the dugout. Starting in 2013, managers will use these phones to call in relievers from the bullpen. According to MLB.com, the phones will be on their own independent network, eliminating reception problems in packed stadiums. Cell phone reception was almost non-existent last season at Nationals Park on days with big crowds. The league also announced plans to improve wireless internet coverage in stadiums, good news to fans.
