The Los Angeles Dodgers have exercised their option on Dave Roberts' contract for 2019 while continuing to work on a long-term deal for the manager who has taken the team to consecutive World Series. ''The reason that we've kind of slowed down a little bit is we've got a lot of coaching staff decisions to make and interviews,'' Friedman said Wednesday at the general manager's meetings. Roberts just finished his third season as the Dodgers' skipper, when Los Angeles lost the World Series in five games to the Boston Red Sox.
