The Seattle Mariners announced their Opening Day roster Friday. One thing I noticed was that despite the absence of right-hander Hisashi Iwakuma, the 25-man group is clearly better than it was one year ago.

There aren’t any surprises here, considering what took place Tuesday and Wednesday.

2013-Bullpen-2014

Easily there are potential and significant upgrades in the bullpen, having added Fernando Rodney and Danny Farquhar since the start of 2013.

2013-Infielders-2014

Robinson Cano is the obvious upgrade here, but Brad Miller at shortstop also presents a sizable upgrade to Brendan Ryan, who couldn’t hit enough top keep his plus-plus glove in the lineup.

2013-Outfielders-2014

There is a defensive upgrade here, with Dustin Ackley acclimating himself to left field and the presence of both Michael Saunders and Abraham Almonte — adequate in center, above average in a corner for both. When Corey Hart hits right field, he may land somewhere between below average and average, but still that is better than Raul Ibanez and Michael Morse.

2013-Catchers-2014

Mike Zunino isn’t likely to light the world on fire at the plate and still has work to do defensively, but he’s light years better than Jesus Montero behind the dish and will provide a significant edge offensively, too, even though he may hit .230/.300/.400. John Buck and Kelly Shoppach may be a wash.
