Seattle Mariners: 5 Trade Target from Diamondbacks Rebuild

David Peralta

Next, on our list, we will take a look at outfielder David Peralta. Coming off a breakout season of clubbing 30 homers and slashing .292/.352/.516, the 31-year-old will be a popular trade target for a lot of teams.

Due to earn roughly $7.7 million in arbitration in 2019, Peralta is a terrific bargain IF he can repeat his output away from Chase Field. Whether or not he can is up for debate. At the hitter-friendly confines of Chase Field, Peralta posted a 161 wRC+ and a .988 OPS. On the road, he posted a league average 100 wRC+ and a .750 OPS.

Peralta is also a bit of a platoon player. In 2018, Peralta bashed RHP to a tune of .318/.377/.568 and a 150 wRC+. Against LHP, he slashed just .237/.294/.399 with a 86 wRC+.

Overall, Peralta is an average defender and slightly above-average base-runner. He puts the ball in play at an above-average pace and takes a decent number of walks. 2018 may be a mirage, but if Peralta could post his 2017 slash line of .293/.352/.444, it could be a decent upgrade in LF over Ben Gamel.

However, Peralta and Gamel may not be significantly different in terms of value, making a deal for the LHH unlikely.

Likelihood of a deal: 5/10

Zack Godley

Yes, the Mariners need another starting pitcher. Yes, I sound like a broken record. But it doesn’t make the statement any less true. Godley will turn 29-years-old in late April, but still has 4 years of club control remaining. As we all know, Dipoto covets club-control, which could make him the most likely player to find his way to Seattle.

However, club-control doesn’t necessarily mean valuable. In 32 starts in 2018, Godley was pretty good. His 4.74 ERA doesn’t jump off the page, but he did post a solid 3.96 xFIP while striking out more than a batter per inning (9.34 K/9).

On top of that, Godley is an extreme groundball pitcher, posting a career 51.6% GB rate. So how could the Mariners even afford to ask about a guy like this? Well, for starters, he has shown iffy, at best, command. His 4.09 BB/9 are a scary number, and he’s never had pinpoint command to begin with.

In addition, Godley has reached his ceiling already, and it’s just that of a #4 or #5 starter. Combined with his age, Godley’s market may be suppressed enough to allow Dipoto to get in on the conversation.

Godley probably slots into the #5 slot in the rotation but is no guarantee to be better than incumbent Wade LeBlanc. He may, however, be an alternative to Sonny Gray, who we expect to be a trade target of Jerry Dipoto’s.

Likelihood of a deal: 4/10

Ketel Marte

Yeah, the Mariners already won the Haniger/Segura for Walker/Marte trade. So why not go out and get Marte back? Well for several reasons really. One, Marte has already been locked in on a long-term deal with the Diamondbacks. His 5 year, $25 million deal is a bargain, which even includes two team options for a total of $18 million.

Second, the Mariners already have Dee Gordon and Jean Segura. Marte is primarily a second baseman who played SS with the Mariners. He actually isn’t terrible at short, but is much better suited for second.

Finally, the 25-year-old is coming off a career year. In 153 games, Marte slashed .260/.332/.437 with 14 home runs. Marte also has his above-average bat-to-ball skills. He has also showed more and more patience as he has matured at the plate posting a 10% BB rate in Arizona.

Marte still posses all the skills he flashed in his short stint as a Mariner. He has plus speed, which he has yet to harness on the basepaths, but still adds value to his overall game. Marte also posses good bat speed, which may mean that his 14 homers is a legitimate target for him moving forward.

Marte is player that can contribute in all 3 phases: hitting, fielding, and running. If the Mariners can find a new home for Segura or Gordon, Marte should be high on their list. However, with the roster set as it currently is, he may not warrant much more than a courtesy call. Marte would be an exciting get for Dipoto, but it just seems unlikely.

Likelihood of a deal: 3/10

Robbie Ray

Okay. Full disclosure: I love Robbie Ray. A lot. And now we learn he may be available? Oh heck yes. Ray is a 27-year-old LHP with 2 years of club control remaining projected to earn $6.1 million in arbitration this off-season.

Ray has more or less been a breakout candidate for each of the past 3 seasons. While he has shown extended flashes, he has never quite put all of his tools together for the entirety of the season. 2018 was a step back for Ray, who battled an injury early in the year that cost him 2 months of the season.

Despite the injury, Robbie Ray still posted solid numbers for the D-Backs, including a 3.77 xFIP and a 12.01 K/9. However, Ray’s already spotty command took a step back in 2018, averaging over 5 walks per 9 innings pitched. Ray’s career mark hovers around 3.8 BB/9, so his command will lower his value.

Ray’s 93-95 MPH fastball is a good pitch, but his bread and butter is his wipe away slider. Ray abandoned his mediocre changeup in 2018, instead opting to throw more curveballs. The pitch grades at well above-average, giving Ray 3 legitimate offerings.

Unless he can find the control that he has always lacked, Ray’s upside will likely be limited to that of a #3 type of starter. Ray also has a history of missing time, only posting more than 162 innings once. However, Ray has been durable enough to make at least 23 starts a year each of the past 4 years.

With Ray’s upside limited, the Mariners may just be able to sneak into a bidding war and win Ray right out from under other pitcher needy teams.
