PHOENIX (AP) -- The Arizona Diamondbacks have extended the contracts of general manager Kevin Towers and manager Kirk Gibson through 2014.
Towers and Gibson each had their contracts extended three years. There also are mutual options for two more years that must be exercised by 2013, but also could be triggered by performance incentives.
Diamondbacks president and CEO Derrick Hall says the team offered the extensions because of how quickly Towers and Gibson turned around the middling franchise in their first full season at the helm.
Arizona won 94 games and reached the first round of the playoffs this year coming off a pair of 90-loss seasons.
The Diamondbacks announced the extensions on Friday.
