Manager: Kirk Gibson didn't look nearly as smart in 2012 with an injury-ravaged team as he had in his managerial debut in 2011, when the Diamondbacks grabbed a playoff spot.

Key reinforcements: 3B-OF Martin Prado, OF Cody Ross, RHP Brandon McCarthy, SS Cliff Pennington, RHP Randall Delgado, RHP Heath Bell, LHP Tony Sipp, C Rod Barajas, 3B Eric Chavez, 1B-OF Eric Hinske.

Gone, not forgotten: OF Justin Upton, OF Chris Young, 3B Chris Johnson, RHP Trevor Bauer, RHP Matt Albers, C Wil Nieves.

Big fun: Adam Eaton, 24, who has a .355 career average in the minors, could be the igniter Young never became because of his high strikeout totals.

Big worry: With Hudson out for the first half of the season, the Diamondbacks need McCarthy to start fast after a fractured skull ended his 2012. His fragile shoulder bears watching as closely as whether he'll flinch on comebackers.

Padres

Last year: 76-86, but a 42-33 second half built some momentum for this season.

Manager: Bud Black remains entrenched despite a .477 career record, with GM Josh Byrnes exercising 2014 and '15 options on Black's contract after last season.

Key reinforcements: RHP Tyson Ross, RHP Freddy Garcia, RHP Fautino De Los Santos, IF Cody Ransom.

Gone, not forgotten: RHP Jason Marquis, RHP Cory Burns.

Big fun: With Chase Headley coming off a breakout season and he and Carlos Quentin committed for two and three years, respectively, the Padres are building some offensive identity after finishing in the bottom half of the NL in scoring for eight consecutive years.

Big worry: Catcher Yasmani Grandal's development is being slowed by a 50-game PED suspension to start the season.

Rockies

Last year: 64-98, with injuries costing Troy Tulowitzki significant time for the fourth season in the last five.

Manager: Walt Weiss, popular in Denver after a four-year run playing for the Rockies in the 1990s, was coaching high school baseball in 2012 and has no big league coaching experience.

Key reinforcements: LHP Wilton Lopez, C Yorvit Torrealba, RHP Chris Volstad.

Gone, not forgotten: 1B Jason Giambi, LHP Jonathan Sanchez, LHP Matt Reynolds.

Big fun: Catcher Wilin Rosario (a Rockies rookie record 28 homers last season) and second baseman Josh Rutledge might not need long to hit their way out of the bottom of the order.

Big worry: The health of Jhoulys Chacin and Jorge De La Rosa, along with the development of lefty Christian Friedrich, is critical as the Rockies scrap the four-man rotation for a more traditional arrangement.
