2016 ZiPS Projections – Seattle Mariners

After having typically appeared in the very hallowed pages of Baseball Think Factory, Dan Szymborski’s ZiPS projections have been released at FanGraphs the past couple years. The exercise continues this offseason. Below are the projections for the Seattle Mariners. Szymborski can be found at ESPN and on Twitter at @DSzymborski.

Other Projections: Atlanta / Baltimore / Cincinnati / Kansas City / New York AL / Philadelphia / Pittsburgh / Texas / Toronto.

Batters
The arrival of Jerry Dipoto in Seattle has been accompanied by considerable turnover within the club’s roster — some of which is represented in the major-league depth chart. Nori Aoki, Chris Iannetta, and Adam Lind all receive projections in the one-win range. Not unexpected, that, but also not a source of great inspiration to the people of Seattle. Then there’s the case of Leonys Martin. Rendered more or less redundant in Texas, the center fielder is projected to produce 2.5 wins in roughly two-thirds playing time, one of the best marks among the club’s position players.

Elsewhere, the strengths of the club remain the same. Robinson Cano, Nelson Cruz, and Kyle Seager are all forecast to record three or more wins. This is particularly encouraging for Cano. After posting a 2.1 WAR in nearly 700 plate appearances this past season, Cano is expected to approach the four-win threshold in 2016.

Pitchers
If one is inclined to put stock in ZiPS, one is inclined also to believe that the version of reality in which Hisashi Iwakuma signs officially with the Dodgers is an unfortunate reality for the Mariners. After Felix Hernandez, the recipient (predictably) of a strong projection, the next best non-Iwakuma mark belongs to left-hander Wade Miley, who barely passes the one-win threshold. The numbers after that aren’t particularly encouraging, either.

With regard to the bullpen, one finds that it features almost an entirely different cast than that which ended the 2015 season. No coincidence, that, in light of how the club’s relief corps finished 26th in the majors by WAR. The prognosis for the 2016 version of the bullpen isn’t wildly encouraging, but suggests an improvement over its predecessor.

Bench/Prospects
While Dan Szymborski’s computer algorithms might seem pessimistic with regard to some of the Mariners’ newest acquisitions, one player for whom that’s not the case is outfielder Boog Powell. The author of precisely zero major-league plate appearances, Powell is forecast by ZiPS to produce 1.5 wins in roughly 500 plate appearances on the strength of reasonable plate-discipline numbers and slightly above-average center-field defense. Among pitchers, the returns aren’t quite so promising. New acquisition Tony Zych is projected for roughly half a win.

Disclaimer: ZiPS projections are computer-based projections of performance. Performances have not been allocated to predicted playing time in the majors — many of the players listed above are unlikely to play in the majors at all in 2016. ZiPS is projecting equivalent production — a .240 ZiPS projection may end up being .280 in AAA or .300 in AA, for example. Whether or not a player will play is one of many non-statistical factors one has to take into account when predicting the future.

Players are listed with their most recent teams unless Dan has made a mistake. This is very possible as a lot of minor-league signings are generally unreported in the offseason.

ZiPS is projecting based on the AL having a 3.93 ERA and the NL having a 3.75 ERA.

Players that are expected to be out due to injury are still projected. More information is always better than less information and a computer isn’t what should be projecting the injury status of, for example, a pitcher with Tommy John surgery.

Regarding ERA+ vs. ERA- (and FIP+ vs. FIP-) and the differences therein: as Patriot notes here, they are not simply mirror images of each other. Writes Patriot: “ERA+ does not tell you that a pitcher’s ERA was X% less or more than the league’s ERA. It tells you that the league’s ERA was X% less or more than the pitcher’s ERA.”

Both hitters and pitchers are ranked by projected zWAR — which is to say, WAR values as calculated by Dan Szymborski, whose surname is spelled with a z. WAR values might differ slightly from those which appear in full release of ZiPS. Finally, Szymborski will advise anyone against — and might karate chop anyone guilty of — merely adding up WAR totals on depth chart to produce projected team WAR.
