The Winter Meetings begin tomorrow in San Diego, CA and all Mariner eyes will be on GM Jack Zduriencik as he continues his push to land a right fielder. With Michael Saunders recently traded to Toronto for starting pitcher J.A. Happ, and newly acquired Nelson Cruz slated to spend the majority of time as the team’s designated hitter, Zduriencik will undoubtedly be working the floor incessantly in order to land a second “big” bat for his offense.

The Mariners have been tied to the Dodgers’ Matt Kemp and the Braves’ Justin Upton for most of the offseason. Both players would represent huge upgrades in right field, but both also come with lofty costs as Los Angeles and Atlanta are said to be asking for blue chip prospects in return, including top pitching prospect Taijuan Walker. Complicating matters even more, Upton would be a one-year rental as he is set to hit free agency as season’s end, and Kemp is owed $107M over the next five seasons.

With the Mariners seemingly not comfortable with the current asking prices for Kemp or Upton (recent reports indicate the Mariners turned down a trade of Walker for Kemp plus $53.5M) Zduriencik is now entertaining the idea of signing free agent outfielder Melky Cabrera.

On the surface, Cabrera makes some sense for the Mariners. His acquisition wouldn’t require the Mariners to part with Walker or James Paxton. And coming off a 2014 season where he slashed a .301/.351/.458 with 16 homeruns, 35 doubles and 3 triples, Cabrera would seemingly fill the Mariners’ need for a right fielder who can wield a productive bat.

However, with dealing Saunders away, the intent of the Mariners presumably is to acquire a player that will significantly improve the offensive production out of right field.

Yet, when examing the numbers closer, Cabrera doesn’t really represent much of an upgrade.

Last year, Cabrera produced a 126 OPS+, a 125 wRC+, a .354 wOBA, and a .458 slugging percentage. Saunders produced a near identical 128 OPS+, 126 wRC+, .346 wOBA, and a .450 slugging percentage. Cabrera did put up a solid .808 OPS, but his OPS was buoyed by two huge months in March/April (.935 OPS) and July (.956 OPS) while the rest of the year consisted of fairly pedestrial monthly OPS’s of .735, .751, .714, and .402.   Saunders ended the season with a lower .791 OPS but was a tad more consistent with OPS’s of .834, .862, and .952 in May, July and September/October.  Saunders’ down months, however, fared worse than Cabrera’s, with OPS’s of .600 and .651 in March/ April and June.

In considering these numbers, we can not overlook the fact that Saunders played in only 78 games last season due to injury and perplexing decisions by manager Lloyd McClendon to keep him on the bench, stemming all the way back to spring training. With that in mind, if we are to look at the numbers from the past two seasons (i.e. Cabrera’s post PED years) Saunders comes out as the more valuable player, producing a 3.2 fWAR in 731 plate appearances to Cabrera’s 1.7 fWAR in 993 plate appearances.  And in looking at 2015, Saunders’ is projected by Steamer to produce a 1.8 fWAR compared to Cabrera’s projection of 1.7 fWAR.

Given those numbers, Cabrera’s asking price is steep; 5-years and somewhere in the neighborhood of $60M-$75M. But keeping in mind the recent contracts given to fellow right fielders Cruz (4 years, $57M) and Nick Markakis (4 years, $44M), such an asking price is not unreasonable.

While Cabrera would undoubtedly bring more expected reliability to the right field position, the numbers show that when on the field, Saunders was as good, or better, than Cabrera.  In addition, the Mariners reportedly would bat Cabrera second, which seems counter-productive considering the dire need for another run producer to hit in the middle of the batting order, as well as the fact the Mariners return Dustin Ackley who produced a .765 OPS serving as the Mariners #2 hitter from July 26th until the end of the season.

All of which begs the question: Is reliability worth paying Cabrera $12M-$15M per year over the next five years to be the Mariners #2 hitter when Saunders would have cost the Mariners merely $3M in arbitration?

If the Mariners are truly looking for a substantial upgrade in right field, Kemp or Upton should be the preferred targets.

Because when you consider that a player like Kemp – who posted an .800+ OPS in all but one month of the season last year, as well as a wRC+ of 140 – could be had for $10M per year over the next five years, even if it requires trading Walker, the idea of signing Cabrera for far more money in order to receive far less offensive production, over the exact same time span, is simply nonsensical.
