RHP Josh Collmenter pitched so well over his final seven starts that he appears to have won himself a spot in the 2015 starting rotation, general manager Dave Stewart said the day after the regular-season ended. "You have (to) look at Josh," Stewart said. "I'm not the guy to say because I'm not going to write the lineup, but you have to assume Collmenter and (Wade) Miley are locks in our rotation." Collmenter, 11-9 with a 3.46 ERA, led the D-backs in victories and finished 10th in the NL in WHIP (1.13). He was 3-2 with a 1.26 ERA in his final seven starts since Aug. 22, trailing only San Francisco RHP Jake Peavy (1.17) and Pittsburgh LHP Francisco Liriano (1.23) in that time frame.

LHP Wade Miley, who reached 200 innings for the second consecutive season, is considered a "lock for the 2015 starting rotation," general manager Dave Stewart said the day after the regular season ended. "You have to look at Wade," Stewart said. "You have to assume (Josh) Collmenter and Miley are locks in our rotation. Miley was 8-12 with a 4.34 ERA in 33 starts and 201 1/3 innings. "It's a goal you set for yourself, but it's not that big of a deal," Miley said of his innings. "I want to maximize innings, throw as much as you can. The more innings you throw, the more you benefit your club." Miley set career highs in strikeouts (183) and walks (75).

RHP Archie Bradley remains the top prospect because of his stuff -- a mid- to-high-90s fastball and a developing breaking pitch despite an up-and-down season in which he was shut down for a month with elbow soreness that did not turn into anything more dramatic. The seventh player taken in the 2011 draft, Bradley has the power arm that plays at the top end of a rotation once he learns location. There are rotation spots open in 2015, but he will not be rushed.

1B Paul Goldschmidt made his second All-Star team while cementing his status as one of the games superstars, albeit without much fanfare. Goldschmidt slashed .300/.396/.542 with 39 doubles, 19 homers and 69 RBIs. He tied for fourth in the NL in doubles despite playing only 109 games before suffering a fractured fourth metacarpal in his left hand when he was hit by a pitch Aug. 1, and would have been second in OPS and slugging but was 23 plate appearances short of qualifying. And there's this -- the D-backs were 16-36 after his injury.

LHP Patrick Corbin (Tommy John surgery) is not expected to return until May or possibly June of 2015 after missing all of the 2014 season as the D-backs take a conservative approach.

2B/SS Chris Owings, SS Didi Gregorius, 2B Aaron Hill, 2B/SS/3B Cliff Pennington and minor league SS Nick Ahmed give the team plenty of depth in the middle infield, but general manager Dave Stewart said it would take a special deal to move one as the D-backs look for help in the starting rotation. "I'm not going to be going into the market looking to actively trade one of our middle infielders," Stewart said, "(but) if it makes sense for our ball club, I'm going to do what's best for the ball club. We need frontline starting pitching. If it allows us an opportunity to get that, we'll have to examine that. We're going to try to maintain what we have. We are going to try to maintain our minor league system."

RHP Trevor Cahill has one of the best two-seam fastballs in the game, and when Cahill arrived via trade in 2012, some compared him to D-backs icon Brandon Webb. But that's where the comparisons stopped. Cahill was so ineffective early this season that he was bumped from the rotation in mid-April, then sent to the minors two months, before returning at the All-Star break. Nothing seemed to work. On a staff that needed someone to step up after left-hander Patrick Corbin suffered season-ending Tommy John surgery in March, Cahill was 3-12 with a 5.61 ERA.

RHP Brad Ziegler, among the league leaders in appearances before being shut down after microfracture surgery on his left knee in early September, hopes to return by the start of spring training, although there is no definitive timetable. "I am excited about the opportunity to come back next spring and show them that it wasn't a mistake not trading me this year," Ziegler said. "That I can be a leader in the bullpen and hopefully it becomes a really good bullpen." Ziegler was 5-3 with one save and a 3.49 ERA, his ERA rising a point as he tried to pitch through the injury he first felt in late June.

RHP David Hernandez (Tommy John surgery) will be 11 months out of surgery when spring training opens in 2015, and he will be delayed at the start of the season.

OF/1B Mark Trumbo finished the season on a roll, with six home runs and 22 RBIs in September while playing mostly first base for injured All-Star Paul Goldschmidt, who missed the final eight weeks of the season with a fractured fourth left metacarpal. Trumbo played most of the season in left field, but general manager Dave Stewart suggested that he might be moved to right field in 2015 if he feels more comfortable there. The D-backs plan to start A.J. Pollock in center field, and rookies David Peralta and Ender Inciarte played all three outfield positions in 2014. Trumbo hit .235 with 14 homers and 61 RBIs in 88 games last season, missing 11 weeks with a stress fracture in his left foot.
