Outside of the Seattle Mariners farm system, both of these players are virtually unknown.

Also, both have taken different routes prior to being put on the Mariners’ active roster list.

Ackley went the college route and played three years for the University of North Carolina.

Not to mention he finished runner-up to Stephen Strasburg for the 2009 Golden Spikes Award (nation’s top amateur baseball player).

As for Pineda, he bounced around through six different minor leagues from 2006 through 2010.

However, currently he ranks as the Mariners’ second best prospect.

The Seattle Mariners look to be on the rise, and 2011 has higher expectations.

Both players have a great amount of potential, but who will be the better Mariner?

There’s only one way to to stir up a discussion.
