Earlier today, the Dodgers announced that Don Mattingly would not return in 2016 as their manager. It was described as a mutual agreement to separate, and now both parties will be allowed to pursue different opportunities. While there appear to be a couple names at the top of LA's list, it's not clear as to who they might interview.
Gabe Kapler
According to Buster Olney, Kapler is a "serious frontrunner to be the Dodgers manager". He's been with Los Angeles since November of last year as their Director of Player Development, and managed Boston's Single-A affiliate for one season in 2007. He has a strong reputation as being analytically inclined, which is likely something that the Dodgers front office will prioritize in their search for a new manager.
Dave Martinez
While the Dodgers missed out on Joe Maddon, they could potentially go after his bench coach, Martinez, who occupied the same role in Tampa from 2007-2014. Earlier this month, Maddon gave his endorsement, saying that "he's definitely ready to manage...When he comes to the ballpark every day, he walks in the door as though he's going to manage the game."
Martinez could very well be considered a frontrunner alongside Kapler, as the Dodgers' president of baseball operations, Andrew Friedman, already has an existing relationship with him.
Ron Wotus
After being named GM of the Dodgers, Farhan Zaidi said he had "plans to analyze the Giants to see if there [were] lessons to be gleaned while building Los Angeles' 2015 roster. 'I think any time a team has that kind of success, you really have to study them hard and see what lesson there are to learn.'"
While most of the credit for San Francisco's success would undoubtedly rest with the players, the front office, and Bruce Bochy, it would be impossible to overlook Ron Wotus if anyone were to study the Giants. He's been their bench coach since 1999, and served under three different managers (Dusty Baker, Felipe Alou, and Bochy). He's been key in positioning San Francisco's infielders, and has blended old school baseball with the new data driven approaches.
Ron Roenicke
Roenicke began the 2015 season as the manager of the Brewers, but ended it as the Dodgers' third base coach. From the moment he was hired, the conspiracy theories began to fly, as Mattingly was seemingly on the hot seat from the day he was named manager.
In four plus seasons as Milwaukee's manager, he lead the team to a record of 353-331 (.508), and took them to the NLCS in his first year.
Bud Black
Black, like Roenicke, also started the year as a manager, but after the Padres started 32-33, A.J. Preller decided that wasn't good enough and fired him. San Diego proceeded to go 42-55 under Pat Murphy, which potentially highlights how great of a job Black was doing with the players he was given.
With Black, the question doesn't seem to be if he'll manage again, but simply when and where. With four managerial openings he could be considered for, there's a strong likelihood that he'll be back in the big leagues in 2016.
