The Mariners acquired Andino from the Baltimore during the offseason for outfielder Trayvon Robinson.The infielder looked lost at the plate this season, hitting .184/.253/.237 through 87 plate appearances.
Andino received a chance to take over the team's starting shortstop role from Brendan Ryan, but Andino could not wrestle the job away. Ryan has hit .191/.262/.236 this season, but has hit .240 since Mariners manager Eric Wedge attempted to hand over the role to Andino.
Triunfel may receive a chance to earn more playing time at shortstop, but Ryan is 11-28 at the plate in the team's last eight games. The 23-year-old has swung the bat well in Triple-A, hitting .300/.351/.476 through 186 plate appearances. Triunfel made his major-league debut with the team last season, hitting .227/.261/.318 in 24 plate appearances.
The Mariners also confirmed the call up of Jesus Sucre to replace Jesus Montero on the team. The team had to place Sucre on the 40-man roster, and made room with the Andino move.
