Mariners trim camp roster to 55 with 13 cuts

Hultzen optioned to Triple-A; Morban and Fernandez optioned to Double-A

PEORIA, Ariz. -- With Minor League camp opening Wednesday, the Mariners cut 13 players from their Major League camp as they began the process of weeding down to an eventual 25-man roster.

The Mariners opened camp with a club-record 68 players, so they still have 55 competing for jobs on new manager Lloyd McClendon's team.

Wednesday's moves included three involving players on the 40-man roster, with injured left-hander Danny Hultzen optioned to Triple-A Tacoma and outfielder Julio Morban and left-hander Anthony Fernandez optioned to Double-A Jackson.

Hultzen, the club's No. 2-ranked prospect, will not play at all this season as he's rehabbing from rotator cuff surgery. Morban, 22, is recovering from a broken ankle that occurred in late August while he was playing for Jackson.

The 10 other players were non-roster invitees, so they were reassigned to Minor League camp. That group included four position players: catchers John Hicks and Manuel Pina, infielder Gabriel Noriega and outfielder Burt Reynolds, who is the cousin of second baseman Robinson Cano.

Also reassigned were right-handed pitchers Jonathan Arias, Andrew Carraway, Stephen Kohlscheen, Mark Rogers and Chance Ruffin and left-hander James Gillheeney.

Of that group, Pina, Rogers and Ruffin have Major League experience. Pina has caught five games with the Royals, Rogers has pitched 11 games for the Brewers, and Ruffin has pitched in 24 games as a reliever with the Mariners and Tigers over the past three seasons.

The Mariners now have 37 roster players and 18 non-roster invitees remaining in camp.
