Well, this was unexpected.
After beating the Mariners, 1-0, this afternoon, completing a sweep of a three game set, Washington Nationals manager Jim Riggleman has resigned per a variety of reports, and apparently initially reported by Ken Rosenthal on Twitter.
The Nationals, despite missing heralded young starter Stephen Strasburg and getting little offensively from big dollar free agent signing Jayson Werth, are 38-37 on the year, putting them third in the N.L. East and exceeding most expectations for the club.
Riggleman, according to reports on Twitter, was unhappy with the way he has been treated by the Nationals, and told g.m. Mike Rizzo before the game that if the club did not pick up its 2012 option on his contract before today's game, that he would resign afterwards. He apparently made good on his threat.
Riggleman managed the San Diego Padres from 1992-1994, the Chicago Cubs from 1995-1999, and was the interim manager of the Seattle Mariners in 2008. He took over as the Nationals' manager halfway through the 2009 season.
