It's hard to quantify a Managerial candidate, there are no real stats , even w/l records can be very misleading as that depends on the team he's given and you don't always know what influence he has on new player acquisitions. Having said that
Jim Riggleman
Riggleman was named bench coach for the Washington Nationals for the 2009 season, and was promoted to interim manager on July 12, 2009 following Manny Acta's midseason dismissal.[5] Riggleman picked McLaren as his bench coach. He was retained as manager for the 2010 and 2011 seasons, but on June 23, 2011, he resigned as manager of the Nationals after a win against the Seattle Mariners and after the team won 11 of its previous 12 games. Riggleman was unhappy that the team had yet to pick up his contract option for the 2012 season. He said he told team management before the game that he "wanted to have a conversation" about his contract before the team left for a series against the Chicago White Sox, but "they didn't want to do that," so he offered his resignation. "I'm 58, I'm too old to be disrespected," he said.[6][7]

Jim Tracy
Tracy was manager of the Los Angeles Dodgers from 2001 to 2005, compiling 4 winning seasons and a 427–383 record. With Tracy as manager, the Dodgers won the National League's West division in 2004 but lost 3-1 to the St. Louis Cardinals in the National League Division Series. On October 3, 2005, after finishing the season at 71-91, Tracy and the Dodgers agreed to part ways citing "philosophical differences."[2]

Neither look exciting to me, Tracy though at least had some success with the Dodgers, so I'd go with him
