The Seattle Mariners have stayed out of the major offseason spotlight for the most part this winter. They haven't signed any franchise players or agreed to any six-digit contracts, but the recent addition of first baseman Kendrys Morales was pivotal for the team, and his success will largely correlate with the success of the organization in 2013.
Morales' 2013 season will be heavily analyzed under the microscope, especially in comparison to how Jason Vargas performs. The Mariners gave up their second best starting pitcher for Morales, so naturally their seasons will be compared.
Morales is a quality hitter when healthy, averaging 28 home runs and 98 RBI per 162 games. His major downfall is his strikeouts. His career 2.75:1 strikeout-to-walk ratio would be great for a pitcher, but that area needs improvement from a hitter's standpoint.
