Mattingly had a 260-225 record in his first three seasons with the Dodgers, who reached the NL Championship Series last season, automatically triggering an extension of his contract that was set to expire at the end the season.
He was runner-up for NL manager of the year.
Last winter, the Dodgers declined to exercise Mattingly's option for 2014, a move he believed portrayed him as a lame duck in the clubhouse.
Iglesias, Tigers agree
The Detroit Tigers have agreed to a one-year deal with shortstop Jose Iglesias.
Iglesias finished second in last year's AL rookie of the year vote, hitting .303 in 109 games with Boston and the Tigers. Detroit acquired him from the Red Sox in a three-way deal before the trade deadline.
Iglesias replaced Jhonny Peralta at shortstop for Detroit while Peralta was serving a drug suspension last season. Peralta has signed with St. Louis.
Iglesias is part of an infield the Tigers hope will be improved defensively in 2014. Miguel Cabrera is moving from third base back to first to replace Prince Fielder, who was traded to Texas.
Roger and out
The Jolly Roger has walked the plank in Pittsburgh. The Pirates announced the franchise will make the gold "P" the team's primary logo, replacing the beloved eye-patch-wearing sailor who has been the club's main symbol for nearly 80 years.
The team will still have the Jolly Roger on the sleeves of some of its uniforms for the time being. Some variation of the Jolly Roger has been a part of the Pirates' identity since 1936, though the classic "P" dates back more than a century.
