The Mariners took steps toward relevance last season, when they finished with the seventh-best record and the fourth-best run differential in the American League. Still, at 86-76, they fell short of the playoffs for a major league-worst 15th year in a row. Team brass is ready to draw that ignominious streak to a close in 2017. Amid an aggressive, trade-packed winter, general manager Jerry Dipoto proclaimed in January that the Mariners are “plainly” in “’win-now’ mode.” Then, just after the start of spring training in February, club president Kevin Mather declared, “It is time to play October baseball in Seattle.”

Needs Addressed
In his second offseason at the helm of the Mariners, Dipoto swung a whopping 15 trades, several of which figure to hugely impact the team’s chances this year. None should carry as much weight as the late-November, four-major leaguer swap that saw the Mariners give up high-potential right-hander Taijuan Walker and unproven shortstop Ketel Marte for a fellow shortstop who has shown flashes of brilliance, Jean Segura, and untested outfielder Mitch Haniger.
In theory, Segura shouldn’t have difficulty serving as an upgrade over Marte, whose .259/.287/.323 batting line in 466 plate appearances made him one of the majors’ least valuable shortstops last season. However, Segura posted a near-identical line as a Brewer from 2014-15 (.252/.285/.331 in 1,141 PAs) before stunningly breaking out in Arizona last year. His success as a Diamondback came thanks in part to better pitch selection (he swung at fewer pitches than ever, both in and out of the strike zone, yet still made contact at a rate in line with career norms) and an emphasis on elevating the ball. Segura’s ground-ball rate dropped roughly 6 percent from the previous two years, while both his fly ball and line drive marks rose. That led to more hard contact and a sizable uptick in power, evidenced by career bests in home runs (20) and ISO (.181), and a stellar .319/.368/.499 line in 694 trips to the plate.
Both Segura’s production with the bat and his baserunning prowess (he stole 33 of 43 bags and ranked 15th in FanGraphs’ BsR metric) made him of the premier second basemen in baseball in 2016. Now, with superstar Robinson Cano locking down the keystone, Segura will play shortstop in Seattle. The 27-year-old has plenty of experience at short, where he lined up in Milwaukee and graded as a passable defender (two Defensive Runs Saved, minus-10.6 Ultimate Zone Rating in 4,253 innings). Segura’s work at the plate will draw more scrutiny, though, and if the gains he made last year prove sustainable, he and Cano will give the Mariners an elite middle infield.
As the most established players in the deal, Segura and Walker understandably drew the lion’s share of attention when Seattle and Arizona consummated the trade. But don’t sleep on Haniger, who will open 2017 as the Mariners’ right fielder. Haniger, 26, got his first taste of major league action last season and hit a forgettable .229/.309/.404 in 123 PAs, though he wasn’t necessarily overmatched (he did log approximately average strikeout and walk rates to go with a slightly above-average ISO). Plus, Haniger has a history of raking at the minor league level. At Triple-A Reno last year, he slashed a video game-like .341/.428/.670 in 312 attempts. It’s true that Haniger posted those numbers in the notoriously hitter-friendly Pacific Coast League, but wRC+ indicates his line was an incredible 85 percent better than the PCL average. Dipoto took notice.
“By the numbers, (Haniger) was able to show that he was the best offensive player (last year) in the minor leagues at any level,” Dipoto told Bob Dutton of the Tacoma News Tribune in January. “He’s also a right-handed batter, and we acquired him for that reason. Mitch is also the one that brings with him a skill set that includes power, and he’s got on-base ability.”
While it’s up in the air how much Haniger will boost the Mariners’ offense this season, odds are he’ll at least help their defense. Back in November, Kyle Glaser of Baseball America (subscription required and recommended) wrote that Haniger is a “good athlete” with “good range” and an “above-average arm.” The Mariners lacked quality defense in right last year, when their primary options – Seth Smith, Franklin Gutierrez and Nelson Cruz – combined for minus-10 DRS and a minus-9.1 UZR.
Seattle was even worse off in left, where Nori Aoki and Smith racked up minus-12 DRS and a minus-10.3 UZR between them. Those two are now out of the organization, and another trade acquisition, ex-Royal Jarrod Dyson, will take over as the Mariners’ No. 1 left fielder. The pickup of Dyson typifies the Mariners’ win-today philosophy – the 32-year-old is only signed through this season, while the player they gave up for him, 29-year-old righty Nate Karns, is controllable through the 2020 campaign.
In previewing Seattle’s offseason in October, I wrote, “Ideally for the Mariners, they’ll upgrade their position player group during the offseason with better defenders and baserunners who can also contribute offensively.” Dyson certainly checks two of those boxes. He’s not much of a hitter (.260/.325/.353 line in 1,539 lifetime PAs), but his defensive and baserunning excellence should combine to make him a valuable addition for the Mariners. Going back to 2012, the first year in which he saw extensive big league action, Dyson has amassed 53 Defensive Runs Saved and a 55.5 UZR – both of which rank among the league’s top seven outfielders over the past half-decade. On the base paths, the speedster swiped between 26 and 36 bags in each of the previous five seasons. He also finished last year with a 5.4 BsR, which placed 19th in the majors.
The other notable newcomer to the Mariners’ starting lineup is Danny Valencia, whom they acquired from the AL West rival Athletics for nondescript pitching prospect Paul Blackburn. The plan was for the right-handed Valencia to platoon with the lefty-hitting Dan Vogelbach at first base, but the former will instead open the season as the everyday option there in the wake of the latter’s minor league demotion. It’s possible the Mariners’ faith in Vogelbach will come back to haunt them. Their offseason belief that he was ready for the majors stopped them from pursuing affordable left-handed hitters like Mitch Moreland, Brandon Moss and Pedro Alvarez, any of whom could have teamed with Valencia to form a satisfactory platoon. On the other hand, Valencia won’t need a partner if his recent success against same-handed pitchers continues. Once unusable versus righties, the 32-year-old combined for a .795 OPS in 602 PAs against them from 2015-16. With his performance against lefties factored in, Valencia quietly hit a tremendous .288/.346/.477 in 895 PAs during the previous two years. That type of production would certainly play at first, where the Mariners will try to hide the defensively challenged third baseman/outfielder.
