The Diamondbacks announced (on Twitter) that they have agreed to terms on extensions with general manager Kevin Towers and manager Kirk Gibson that will keep them under contract beyond the 2014 season. Arizona declined its 2015 options on Towers and Gibson following the 2013 season, MLB.com's Steve Gilbert notes, but ownership never had much doubt in the pair.
"We’re very happy with both of them," president and CEO Derrick Hall told Gilbert at the time of the option decision. "They’re under contract and they can still be extended. It’s not a big deal. We’re all on the same page." Managing partner Ken Kendrick offered similar sentiments: "I’m comfortable with those guys. I think it’s important for them to go out and prove themselves once again. I hope and believe they’re going to be long-term Diamondback people."
Gibson took over as the D-Backs' manager midway through the 2010 season and has posted a 290-279 record since that time. He's led the Snakes to an NL West division championship (2011) in that time and also finished runner-up to the Dodgers in 2013. Gibson was named National League Manager of the Year in his first full season at the helm in 2011.
Towers was hired as the D-Backs' full-time general manager in September 2010, replacing interim GM Jerry Dipoto (who is now GM of the Angels). Towers has more experience than nearly any general manager in baseball, as he served as GM of the Padres from 1995 to 2009. His moves since taking the reins in Arizona can be viewed in MLBTR's Transaction Tracker.
Some of the more notable deals include his trade of Justin Upton (along with Chris Johnson for Martin Prado, Randall Delgado, Zeke Spruill and Brandon Drury), his trade for Aaron Hill (in exchange for Kelly Johnson) and subsequent extension and his trade for Trevor Cahill and Craig Breslow (in exchange for Jarrod Parker, Ryan Cook and Collin Cowgill). In addition to Hill, Towers has also extended Paul Goldschmidt (five years, $32MM), Prado (four years, $40MM) and Miguel Montero (five years, $60MM). This offseason's most notable move came at the Winter Meetings when he landed Mark Trumbo in a three-team trade that sent Adam Eaton to the White Sox and Tyler Skaggs to the Angels.
