Rangers set roster with all-righty bullpen

OAKLAND -- The Rangers have set their Opening Day roster without any more moves to reinforce their injury-taxed bullpen.

Instead the Rangers placed five more players on the disabled list, designated left-hander reliever Sam Freeman for assignment and purchased the contracts of relievers Keone Kela and Anthony Bass from Triple-A Round Rock.

The Rangers had held out hope of adding a left-handed reliever before Sunday's roster deadline. Instead Kela and Bass join an all-righty bullpen that includes Phil Klein, Roman Mendez, Logan Verrett, Shawn Tolleson and closer Neftali Feliz.

The Rangers placed right-hander Yu Darvish on the 60-day disabled list, and he is expected to miss the entire season while recovering from Tommy John elbow reconstruction surgery.

The Rangers also placed pitchers Matt Harrison, Tanner Scheppers, Lisalverto Bonilla and Kyuji Fujikawa on the 15-day disabled list. Scheppers (sprained right ankle) and Fujikawa (strained right groin muscle) are expected to be back at some point in mid-to-late April.

Scheppers was placed on the disabled list retroactive to March 29 and is eligible to come off April 13. Fujikawa went on retroactive to April 1 and is eligible to come off April 16. Bonilla has been shut down from throwing and is not likely to return until May at the earliest. Harrison, rehabbing from last year's back surgery, will continue his throwing program in Arizona and is not expected back until July at the earliest. He could end up on the 60-day disabled list if the Rangers need a spot on the 40-man roster.

With Freeman, the Rangers have 10 days to trade, release or get him through outright waivers to the Minor Leagues. The club is hoping to get him through waivers and pitching at Triple-A Round Rock.

Verrett strikes out the side

The Rangers' roster includes just eight players who were with them on Opening Day last year. Tolleson is the only pitcher to be on both the 2013 and '14 Opening Day rosters. The returning position players are catcher Robinson Chirinos, infielders Prince Fielder, Elvis Andrus, Adrian Beltre and Mitch Moreland, and outfielders Shin-Soo Choo and Leonys Martin.

The Rangers have six rookies on the Opening Day roster, the most in club history. The six rookies are Klein, Verrett and Kela, and outfielders Ryan Rua, Jake Smolinski and Delino DeShields. The last time the Rangers had five rookies on the Opening Day roster was in 1993. Both Verrett and DeShields are on the roster as Rule 5 Draft picks. This is the first time in club history the Rangers have had two Rule 5 picks on the Opening Day roster.
