Some players are on the verge of stardom, others are entering a crucial phase of their development and still others are getting their first tastes of full-season ball. With the 2015 season approaching, MiLB.com takes a look at the most intriguing prospects from each MLB organization.

Loudest tool: Joey Gallo's power

Any person who's followed the Texas Rangers Minor League system even a little bit over the last couple seasons has heard all about Joey Gallo's power stroke, and with good reason.

Last year, the only player in pro baseball to hit more homers than Gallo was the Cubs' Kris Bryant, who swatted one more than Galllo's 42. In 2013, Gallo's 40 were the most in the Minors. In his rookie campaign of 2012, he set an Arizona League record with 18 in just 43 games. MLB.com's Jim Callis has already predicted that Gallo will reclaim the Minors homer crown this year, praising the 21-year-old corner infielder's "tremendous strength" and "considerable bat speed."

Superlatives are good and fine, but perhaps the best way to get a sense of Gallo's power is to stare it in the face.

Shining star: Jorge Alfaro, C

While he won't put up Joey Gallo-type homer numbers, Alfaro is another prospect with a strong and powerful swing, and his all-around game could develop to the point that he's a Major League All-Star catcher in the next few years.

After playing in the infield for the bulk of his amateur career, Alfaro caught in 26 of 48 Dominican Summer League games he played in his first pro year, 2010. The 21-year-old Colombian has steadily increased his workload behind the plate since. He's always had rocket for an arm, but his ball-blocking ability and other defensive skills have come a long way over the last couple seasons.

"There are a lot of intricacies involved to play that position well. And to his credit, he's worked really hard, and we've seen him consistently improve more and more," said Rangers senior director of Minor League operations Mike Daily during the third week of March. "He's doing a great job behind the plate in Major League camp now."

Alfaro has hit more than 20 doubles in every full season he's played, and he's mashed 35 homers over the last two years. He's also averaged more than a strikeout per game his entire pro career. If he can cut down on those, he'll increase his walks and likely also see more pitches he can hit against or over a fence.

"Jorge's the type of hitter that has the chance to hit for average and to hit for power. As he continues to develop and progress at each level, he's going to strike out, but controlling the strike zone a little better is something he's working on," Daly said.

"Most good hitters have a good idea of the strike zone, and he's working on that. We're happy with where he is. He got to Double-A and his batting average didn't drop. As he continues to get at-bats and gain more knowledge of the strike zone and more knowledge of swinging at his pitches, [the strikeout numbers] will likely come down."

Full-season debutant: Luis Ortiz, RHP

The Rangers scored Ortiz with the 30th overall pick of last year's Draft, snagging him out of a California high school 15 miles outside of Fresno. At 19, he'll see what he can do against Class A hitters in the South Atlantic League.

"I think that we're, for a first-year guy, hoping to 110 innings, or 115 innings," Daly said. "He'll go out to Hickory and start there. He'll have a pretty normal workload for a first-year guy."

But though Ortiz's workload is normal, his potential is anything but.

"He's a very good strike-thrower for a kid at such a young age. He has great movement and great command of his fastball, and the ability to throw quality secondary pitches and throw them for strikes," Daly said. "The combination of him having the ability to throw strikes and having some power to his arsenal -- and a change that continues to develop -- is very exciting."

Another teenager, the Venezuelan-born Yrizarri is poised to provide thrills for the Class A Short Season Spokane Indians in the Northwest League. It's possible although unlikely that he'll even start out at a higher level.

"He's in competition for [a shortstop job with] Hickory," Daly said. "To be honest... I think the next logical step for him is [Class A Short Season]. I think that's a realistic goal, and he'll still be one of the youngest players in the league."

Yrizarri, the nephew of former big leaguer Deivi Cruz, has only played 60 Rookie-ball games as a pro so far, and his .249 average isn't as good an indicator of his potential as the 19 extra-base hits he notched during that span. He can drive balls to the gaps, and he has the speed to get the most out of them. Defensively, his arm is a standout tool.

"His tools certainly play," Daly said. "He's going to have every opportunity to develop with the bat, and he has the ability to play shortstop. Yesyon's biggest thing is to continue to get experience. He's a hard-worker, and he's got loud tools. We're trying to get him the opportunity to play as much as possible."

Major League-ready: Anthony Ranaudo, RHP

Acquired by Texas in the offseason trade that sent Robbie Ross to Boston, Ranaudo already has seven big league starts under his belt and this was his second Spring Training competing with Major Leaguers. Whether he'll spend considerable time this season polishing his game with Triple-A Round Rock or there's an immediate and long-term spot for him in the Rangers rotation is another matter.

"He's doing everything in his power to put himself in that position," Daly said. "He's in the fight with a couple of other guys, Nick Martinez and Nick Tepesch. The guy has had a ton of success coming out of LSU, a couple Pitcher of the Year awards at Double-A and Triple-A. There's not much else for him to prove."

Ranaudo's fastball and curve are both plus pitches, and although he struggled with his command in his Major League opportunities last year, he struck out 111 and walked 55 over 24 Triple-A starts.

More to keep an eye on: The Rangers have another strong breakout candidate in righty Jose Leclerc, who's put up a 2.74 ERA over four seasons with all but one of his 120 pro appearances coming out of the bullpen. This year, the Rangers will try him as a starter at Double-A Frisco. ... Ryan Rua who played more at third base than anywhere else during his Minor League career, is slated to open the season as the Rangers' left fielder. ... Right-hander Alex "Chi Chi" Gonzalez absolutely perplexed hitters between Class A Advanced and Double-A ball last year, and he had a 3.95 ERA through his first four Cactus League appearances. He'll try his hand in the Pacific Coast League at the start of the season. ... Jake Thompson, another righty and the top pitching prospect in the system according to MLB.com's rankings, may join Gonzalez in the Round Rock rotation before long. It's likely he'll first look to pick up where he left off in the Texas League last year -- after coming to the Rangers in the July 24 trade that netted the Tigers Joakim Soria, Thompson was 3-1 with a 3.28 ERA.
