Answer based on context:

The 2010 Atlanta Braves Season features the Braves attempt to reclaim a postseason berth for the first time since 2005 Atlanta Braves season. The Braves were once again skippered by Bobby Cox, now in his 25th and final season managing the team. The Braves started the 2010 season slowly and had a nine-game losing streak in April. Then they had a nine-game winning streak from May 26 through June 3, the Braves longest since 2000 Atlanta Braves season when they won 16 in a row. On May 31, the Atlanta Braves defeated the then-first place Philadelphia Phillies at Turner Field to take sole possession of first place in the National League East standings, a position they had maintained through the middle of August. The last time the Atlanta Braves led the NL East on August 1 was in 2005 Atlanta Braves season. On July 13, 2010 at the 2010 MLB All-Star Game in Anaheim, Braves catcher Brian McCann (baseball) was awarded the MLB All-Star Game MVP Award for his clutch two-out, three-run double in the seventh inning to give the National League its first win in the All-Star Game since 1996 MLB All-Star Game. He became the first Brave to win the All-Star Game MVP Award since Fred McGriff did so in 1994. The Braves made two deals before the trade deadline to acquire Álex González (shortstop, born 1977), Rick Ankiel and Kyle Farnsworth from the Toronto Blue Jays and Kansas City Royals, giving up shortstop Yunel Escobar, pitchers Jo-Jo Reyes and Jesse Chavez, outfielder Gregor Blanco and three minor leaguers. On August 18, 2010 they traded three pitching prospects for first baseman Derrek Lee from the Chicago Cubs. On August 22, 2010 against the Chicago Cubs, Mike Minor (baseball) struck out 12 batters across 6 innings; an Atlanta Braves single game rookie strikeout record. The Braves dropped to second in the NL East in early September, but won the NL Wild Card. They lost to the 2010 San Francisco Giants season in the 2010 National League Division Series in four games. Every game of the series was determined by one run. After the series-clinching victory for the Giants in Game 4, Bobby Cox was given a standing ovation by the fans, also by players and coaches of both the Braves and Giants.

For how many years did Cox manage the Braves?
