Breaking down Rangers' pitching staff

SURPRISE, Ariz. -- The Rangers have 32 pitchers in camp. Here is how they break down:

The starters
1. Colby Lewis
2. Derek Holland
3. Yu Darvish
4. Matt Harrison
5. Neftali Feliz
6. Alexi Ogando
7. Scott Feldman

Outlook: Ogando and Feldman are likely headed to the bullpen unless there is an injury. Harrison is not guaranteed anything but would have to slip badly to lose his spot in the rotation.

Future starters
1. Martin Perez
2. Neil Ramirez
3. Robbie Ross
4. Jacob Brigham
5. Roman Mendez

Outlook: Perez could win a spot in the Rangers bullpen as a left-handed reliever but the most likely scenario is for all five of these highly regarded prospects to start the season somewhere in a Minor League rotation. Mendez, 9-1 with a 3.30 ERA at Class A Hickory last season, was one of three players acquired from the Red Sox for catcher Jarrod Saltalamacchia. He is just 21 years old.

Bullpen veterans
1. Joe Nathan
2. Mike Adams
3. Mark Lowe
4. Koji Uehara
5. Yoshinori Tateyama

Outlook: Of these five, Tateyama is definitely not guaranteed a job. Trade talks for Uehara have subsided for now but could be revived later. Remember Ogando and Feldman are likely headed this way as well.

RH bullpen candidates
1. Mark Hamburger
2. Tanner Scheppers
3. Cody Eppley
4. Justin Miller
5. Sean Green
6. Greg Reynolds

Outlook: Scheppers has been a starter and a reliever in the past. But the Rangers have decided to use him strictly as a reliever and he has a shot to crack the bullpen.

Hamburger established himself as a top relief prospect by posting a 3.39 ERA and a 1.093 WHIP in the Minors last year. Miller did the same with a 1.81 ERA and a 1.005 WHIP at Double-A Frisco. Eppley was the Rangers Minor League Relief Pitcher of the Year in 2010 who pitched in 10 games for the Rangers last year. All three could be swing relievers this season -- going back and forth from the Minors -- because they all have options.

Green has made 264 relief appearances over a six-year career with the Mariners, Mets and Brewers with a 4.41 ERA and a 1.517 WHIP. Reynolds, acquired from the Rockies for first baseman Chad Tracy, is a former No. 1 draft pick who is more of a reclamation project and could still be a starter at Triple-A.

LH bullpen candidates
1. Michael Kirkman
2. Joe Beimel
3. Mitch Stetter
4. Ben Snyder
5. Kelvin De La Cruz
6. Miguel De Los Santos

Outlook: Kirkman has been a starter in the Minors but now is now strictly a reliever and the leading candidate among left-handers. Beimel and Stetter have had success at the Major League level as left-handed setup relievers. Snyder and Cruz are long shots.

De Los Santos, 23, is a dark-horse candidate to watch after he pitched so well in the Arizona Fall League. Opponents hit .178 off him and he struck out 40 in 30 1/3 innings.

Long-term projects
1. Matt West
2. Wilmer Font
3. Fabio Castillo

Outlook: West was converted from infielder to reliever because of his power arm and could come quickly. Font is on the rebound from Tommy John surgery. Castillo had a 6.36 ERA at Double-A last year and was non-tendered in December. He stayed with the Rangers on a Minor League contract.
