The Braves and Dan Uggla have agreed to a five-year contract extension, the team has officially announced.

The deal is worth $62MM, reports Ken Rosenthal of FOX Sports. Dave O'Brien of the Atlanta-Journal Constitution tweets that the salary in the first year of the deal is $9MM, plus a $1MM signing bonus. The salaries then even out to $13MM annually over the four remaining years. It's the highest average annual salary for a second baseman in baseball history. Uggla is represented by Terry Bross.

Atlanta acquired the 30-year-old Uggla (31 in March) from the Marlins in exchange for Omar Infante and Michael Dunn soon after he turned down a four-year, $48MM extension offer. The new contract covers his final year of arbitration eligibility and four free agent years. Uggla earned $7.8MM in 2010.

Despite being a middle infielder, Uggla is one of the game's most consistent sluggers. He's hit between 31 and 33 homers in each of the last four seasons, making him just one of nine players to go deep 30 times every year since 2007. A career .263/.349/.488 hitter, Uggla enjoyed his finest season in 2010 thanks to a .287/.369/.508 batting line with career highs in homers (33) and RBI (105). UZR rates his defense as consistently below average.

According to MLBTR's Transaction Tracker, this is the largest contract the Braves have given out since signing Andruw Jones to a six-year, $75MM deal way back in 2001. Only four players – Cliff Lee, Carl Crawford, Jayson Werth, Troy Tulowitzki – have signed for more guaranteed money this offseason. Carlos Gonzalez figures to join that group shortly. The two sides were reportedly close to a deal last month.
