Minor League infielder Carlos Triunfel, rated in the top of five among Mariners prospects, is expected to miss about eight weeks of the regular season with a broken tibia in his left leg.

The 19-year-old from Puerto Rico was injured while sliding into second base on Friday night trying to break up a double play in Double-A West Tennessee’s Southern League game against Montgomery.

He was taken from the stadium to a hospital and listed in “good condition” according to the Montgomery (Ala.) Advertiser.

Triunfel, the youngest player in the Arizona Fall League last year, was signed by the Mariners in 2006 as a non-drafted player.
