Meet the 2015 Arizona Diamondbacks

In advance of Opening Day, Diamondbacks insider Nick Piecoro talked to a panel of six scouts whose coverage assignments during spring training include the Diamondbacks. Here are the players that made the 25-man Opening Day roster.

Pitchers: RHP Josh Collmenter

Vitals: 6-4, 235

Age: 29

2014: 3.46 ERA, 1791/ 3 innings

Scout's take: "I love Collmenter. He's on a championship team for me but just not in an Opening Day starter role. He could be a back-end starter or a swingman on a championship club. Hitters have a tough time picking up that cut piece up in the zone, he spots it where he needs to spot it and he has a vicious change-up. He's a good pitcher."

RHP Jeremy Hellickson

Vitals: 6-1, 190

Age: 27

2014: 4.52 ERA, 632/ 3 innings

Scout's take: "He's been a good performer in the American League East and I expect him to perform well. He's not a hard thrower, but he works off that change-up and he's getting his feel. During the year, that change-up is going to be hard for clubs to negotiate and he's going to miss bats with that fastball. He'll freeze guys. He can really, really pitch. He's going to be fine."

RHP Chase Anderson

Vitals: 6-1, 194

Age: 27

2014: 4.01, 1141/ 3 innings

Scout's take: "I'm a big Chase Anderson guy. This guy should be in the rotation based on past performance and based on how he pitched this spring. It's never been a question of stuff, it's been a question of health. As long as he's healthy, he's a guy I want in my rotation. I've always thought he's a pretty dependable back-end guy."

RHP Rubby De La Rosa

Vitals: 6-1, 225

Age: 26

2014: 4.43 ERA, 1012/ 3 innings

Scout's take: "It's really good stuff at times besides the lack of the breaking ball, but he doesn't have much room for error – not a good downhill plane type guy and when he leaves it up he gets hits hard. I think he's a bullpen guy. At this stage, he's 26, he's had a couple of years to harness that pitchability and it's been hard for him to obtain it. Not saying he can't do it but the timeline is running thin."

RHP Archie Bradley

Vitals: 6-4, 230

Age: 22

2014: 4.45 ERA, 83 innings

They said it: "If (Bradley) had needed more work," said Tony La Russa, the Diamondbacks' Chief Baseball Officer, "Cahill would still be here."

RHP Daniel Hudson

Vitals:

6-3, 235

Age: 28

2014: 13.50 ERA, 22/ 3 innings

Scout's take: "I saw him one time early in the spring and his velocity was 94 and I was really impressed, coming back from what he's been through. I was impressed with everything – his presence on the mound was good, his confidence. I thought he was a definite rotation guy when I saw him, but if he's not going to throw more than 85 pitches, that only gets you through five or six innings. I don't know what they'll do with him."

RHP Brad Ziegler

Vitals: 6-4, 220

Age: 35

2014: 3.49 ERA, 67 innings

Scout's take: "All you can do is wait and see how the knee responds. It's not just that he had microfracture, it's that it's a pretty unique delivery and you wonder if that will affect him compared to someone with a more traditional delivery. If the stuff is there, he's probably going to be their most consistent reliever, that's what he's always been."

RHP Evan Marshall

Vitals: 6-2, 225

Age: 24

2014: 2.74 ERA, 491/ 3 innings

Scout's take: "The guy broke into the big leagues last year and really ended up being a quality option out of the bullpen. He's got back-end type stuff. He's got swing-and-miss ability in there and he throws strikes. He can sink the ball and get ground balls and not give up home runs. Strikeouts and ground balls are a good combination for a back-end guy. He's a solid option for them."

RHP Addison Reed

Vitals: 6-4, 230

Age: 26

2014: 4.25 ERA, 591/ 3 innings

Scout's take: "I think he's the best of what they've got in terms of their options at closer. He's a perfectly serviceable closer. I thought he took a little bit of a step forward last year because he had better strikeout ability, did a little better job with his fastball location at times. There just wasn't as much consistency as you want to see."

LHP Oliver Perez

Vitals: 6-3, 220

Age: 33

2014: 2.91 ERA, 582/ 3 innings

Scout's take: "He has nasty stuff, and when he's commanding the fastball, he's really, really good, tough to hit for righties and lefties. He's a great guy, a good clubhouse guy, good teammate, comes to the park and works hard. Good guy. His stuff is hard to pick up. He has good angle. Hitters never have a comfortable at-bat against him."

RHP Randall Delgado

Vitals:

6-4, 220

Age: 25

2014: 4.87 ERA, 772/ 3 innings

Scout's take: "He's pitched well for me every time I've seen him. He doesn't make the rotation for me, but I think you need him in the bullpen as a long guy. His velocity has always been fine – the fastball is pretty straight – but the change-up has always been the out pitch. This year, his breaking pitch is better. He's never been able to spin it that well, but he has this year in spring training. It's a legitimate pitch for me."

LHP Andrew Chafin

Vitals: 6-2, 225

Age: 24

2014: 3.86 ERA, 14 innings

Scout's take: "Ever since he was in the Cal League, he's always been a bullpen guy for me. I think that's where the stuff is going to play better. I think the velocity will be better and hopefully it helps with his control and command. This spring, I've had him 90-93 mph with the fastball and the slider from 80-83 mph."

Position players: C Tuffy Gosewisch

Vitals:

5-11, 200

Age: 31

2014: .225 AVG, .553 OPS

Scout's take: "The more that I see him, the more I think he's such a competitor. He's one of those guys who is going to fight so hard at the plate that he's going to dump in some singles and doubles. I like him as a defender. I think he's a good receiver. He's a better choice than anybody they've got right now. That doesn't mean they shouldn't try to find somebody else, but I don't know where that's going to come from that is enough of an improvement over what they have."

C Gerald Laird

Vitals: 6-1, 230

Age: 35

2014: .204 AVG, .532 OPS

Scout's take: "It doesn't look like there's a whole lot left in the tank, but for what he's being asked to do, which is provide some backup to Tuffy, I think he can fill that role just fine. He's a guy who looks his age right now. I think handling the staff will be the key for him, more than anything he does in terms of catching or throwing."

1B Paul Goldschmidt

Vitals: 6-3, 225

Age: 27

2014: .300 AVG, .938 OPS

Scout's take: "What can I say about Goldschmidt that hasn't already been said? His work ethic is outstanding, his aggressiveness, the way he battles with two strikes, especially when the game is on the line. He's got to be one of the best players in baseball. The other thing is, he's not a prima donna. He'll bust his butt on a ground ball. He gives full effort from the first inning to the ninth inning."

2B Aaron Hill

Vitals: 5-11, 200

Age: 33

2014: .244 AVG, .654 OPS

Scout's take: "For me, he's probably the definition of an average second baseman, both offensively and defensively. He's going to make the plays he's supposed to make, but he's not a flashy, athletic type of guy like that. But you still know what to count on from him. I think you can expect him to hit .270 with 10 to 15 home runs and play his position average."

3B Jake Lamb

Vitals: 6-3, 205

Age: 24

2014: .230 AVG, .636 OPS

Scout's take: "He's had an impressive spring. Just the quality of the at-bat, the consistency of the at-bat, he doesn't look like a young hitter, especially after some of his struggles in the big leagues last season. He has a feel for the strike zone, he handles left-handed pitching pretty well, and even when he makes an out, you don't feel like he's getting fooled a whole lot, especially for a young hitter."

SS/2B Chris Owings

Vitals: 5-10, 190

Age: 23

2014: .261 AVG, .706 OPS

Scout's take: "I think he's poised to have a good year. I think everybody is expecting him to take a step forward both offensively and defensively. He's had some time in the league to adjust a little bit and step forward and be kind of a guy in that lineup."

SS Nick Ahmed

Vitals: 6-2, 195

Age: 25

2014: .200 AVG, .504 OPS

Scout's take: "Man, he's one of the best young defensive players. Athletic, instincts, everything you want, he can do it. The question is with his bat. He got called up to the big leagues and the bat was light. It's a tough one there. You love the defense. Any pitcher or pitching coach would take the defense, but he's got another good young player ahead of him. He's in a tough spot. But I like him."

INF Cliff Pennington

Vitals: 5-10, 195

Age: 30

2014: .254 AVG, .690 OPS

Scout's take: "He's the same guy as always. Steady defense, a competitive at-bat every time. He's not going to be a dominant force offensively, but he's a quality, upper-end utility guy with value added in that he switch hits, plays all three infield positions and always makes the routine play."

INF Jordan Pacheco

Vitals: 6-1, 200

Age: 29

2014: .255 AVG, .632 OPS

Scout's take: "He's a nice piece for a National League team. He can give you that third catcher or be the backup, and he swings the bat. He walks up there and can swing the bat. For someone who doesn't get regular at-bats, it doesn't seem to affect him. He does a solid job. There are guys who, if you can play a position really well, you've got a backup spot. But he doesn't play any position particularly well so that sort of makes it tough on him. But he goes up there and swings the bat.

OF Ender Inciarte

Vitals: 5-10, 185

Age: 24

2014: .278 AVG, .677 OPS

Scout's take: "I think he's a major league center fielder. He's grown on me. I think he helps that team right now, with his baserunning, defense and contact skills at the top of the order. I think you make room for him. He went from a guy who I thought was a backup to someone who could be an everyday player. I think there are probably teams out there right now that would love to have him as their everyday center fielder."

OF David Peralta

Vitals: 6-1, 215

Age: 27

2014: .286 AVG, .770 OPS

Scout's take: "He's impressed me. He goes up to the plate swinging the bat. He likes the fastball and he attacks it. The question is if he's going to make the adjustment to the off-speed stuff. As the league makes adjustments to him, how is he going to make adjustments back? At the end of the year, it looked like he was having some trouble with that."

CF A.J. Pollock

Vitals: 6-1, 195

Age: 27

2014: .302 AVG, .851 OPS

Scout's take: "He is a guy that I freely admit I was light on coming up. And it kind of speaks to the issue of makeup in terms of getting the most out of your tools. He's turned himself into one of the better center fielders in the game because of his makeup and instincts, as opposed to raw tools."

RF Mark Trumbo

Vitals: 6-4, 225

Age: 29

2014: .235 AVG, .707 OPS

Scout's take: "I like some of the things he's done this spring. He's gone to right field with some pitches and he's hit home runs to left field. I've always liked him because he's a gamer as well as being a big bopper. He makes adjustments and he'll do what he has to do to be successful. He's not a good outfielder. He makes the routine plays fine and throws fine. But the non-routine ones are tough."
