Carlos Vargas

The D-backs and Mariners on Wednesday agreed to one of the first notable trades of the offseason, with Seattle sending third baseman Eugenio Suarez to Arizona in return for reliever Carlos Vargas and catcher Seby Zavala. Both teams have announced the deal. The trade gives the Diamondbacks the power-hitting third baseman they were looking for while the M’s pick up a controllable power arm, a backup catcher option and shed some meaningful salary.

Suarez, 32, has spent the past two seasons in Seattle after coming over from the Reds alongside Jesse Winker in the trade that sent Justin Dunn and Brandon Williamson to Cincinnati. While the trade was originally more about the Mariners absorbing the remainder of Suarez’s contract in order to acquire Winker on the heels of an excellent couple seasons at the plate, it was Suarez who rebounded and wound up providing the Mariners with the middle-of-the-order punch they’d been targeting.

Suarez clobbered 49 home runs back in 2019 — the second season of a seven-year, $66MM contract extension he’d signed with the Reds prior to the 2018 campaign. His bat tailed off considerably in 2020-21, however, and the Reds shopped him around as they looked to pare back payroll coming out of the pandemic-shortened 2020 season, which was played without fans and came with substantial revenue losses for all 30 clubs.

Upon landing in Seattle, Suarez was largely back to form. While still quite strikeout prone, he popped 31 long balls in 2022 and posted an overall .236/.332/.459 batting line that was about 30% better than league average after adjusting for home park and league run-scoring environment (by measure of wRC+). His 2023 season wasn’t as successful. Suarez posted very similar batting average and OBP marks, but his power dropped off considerably. He complemented this past season’s .232/.323/.391 batting line and 22 homers with his best defensive showing in quite some time (at least in the estimation of Statcast, who credited him with 11 Outs Above Average).

Suarez’s overall approach at the plate, however, is a profile from which the Mariners have voiced a desire to move on. Seattle president of baseball operations Jerry Dipoto said earlier this month at the GM Meetings that he was looking to add high-contact hitters to his lineup — an understandable goal after his team’s 25.9% strikeout rate ranked second in all of Major League Baseball this season. Finding a trade partner for Suarez, in that specific regard at least, is addition by subtraction; Suarez fanned in 30.8% of his plate appearances in 2023 and 31.2% in 2022.

The 2024 season is the final guaranteed year on that $66MM contract for Suarez. He’s owed an $11MM salary plus at least a $2MM buyout on a $15MM option for the 2025 season. In all, the trade trims $13MM of guaranteed salary off the Mariners’ books. It also creates a notable hole at the hot corner, however. Recent trade acquisition Luis Urias is one potential option for the M’s, but he’s coming off a down season and was picked up in buy-low fashion. Presumably, a win-now club like the Mariners would want a more solid option at the position. Time will tell whether the Mariners find that player via free agency or, more likely (at least based on Dipoto’s track record), via trade.

As for the D-backs’ end of things, even Suarez’s slightly diminished 2023 production would be an improvement over their third basemen this past season. Arizona third basemen combined for a dismal .234/.303/.340 line in 2023. Suarez probably isn’t going to help out in terms of batting average, but he should bring more power to the position at a relatively reasonable price point of $13MM. Arizona now projects for about a $114MM payroll, per Roster Resource, which checks in $10MM shy of last year’s mark and about $18MM shy of their franchise-record level, established in 2018.

The trade fills at least one immediate need for the Mariners, who watched Tom Murphy become a free agent at season’s end. Zavala gives them an option to replace him as Cal Raleigh’s backup behind the plate.

The 30-year-old Zavala has tallied 514 plate appearances in the big leagues but mustered a tepid .210/.275/.347 slash in that output. While he’s shown above-average power at times in the minors — including a 20-homer showing in 82 games of Triple-A ball in 2019 — Zavala’s output at the plate has been undercut by his own prolific strikeout rates. He’s gone down on strikes in 35.8% of his Major League plate appearances to this point in his career. He won’t come to the plate nearly as often as Suarez, however, so even though Zavala has his own contact issues, the swap could still prove to bolster the team’s overall contact skills, as has ostensibly been one of their goals.

Furthermore, Zavala grades out as a strong defender behind the dish. Statcast rates him as above-average in terms of blocking balls in the dirt, and he’s regularly drawn plus framing grades both at FanGraphs and via Statcast. Zavala’s 14% caught-stealing rate this past season was well shy of the league-average 20%, as is his career 17% mark. He nabbed a roughly average 24% of would-be base thieves in 2022, however, and he’s hardly the only backstop who struggled to control the running game in 2023, when MLB’s new rules regarding pickoffs and slightly larger bases dramatically increased stolen bases throughout the league.

Zavala doesn’t have any minor league options remaining, so he’ll have to open the season on the Mariners’ active roster or else be traded or placed on outright waivers. It’s always possible they add another backup catcher to supplant him, but for now he stands as the clear favorite to back up Raleigh heading into next season.

The piece of the trade with larger appeal for Seattle could very well be the flamethrowing Vargas, who made his MLB debut with Arizona in 2023. Vargas pitched in just 4 2/3 innings (allowing three runs) and had suspect surface-level numbers in Triple-A Reno: 7.02 ERA, 17% strikeout rate, 15.1% walk rate. Grisly as those numbers may be at fist glance, however, there’s also a fair bit of intrigue around the young righty.

Vargas only just turned 24 last month, and in his brief time on the D-backs’ big league roster, he averaged 99.4 mph on his four-seamer and 98.8 mph on his sinker. Per Statcast, only seven of the 851 pitchers who tossed at least one inning last year averaged a better mark on their four-seamer and sinker. Vargas is one of the game’s hardest-throwing pitchers, and his sinker produced a massive 59% ground-ball rate in Triple-A.

When considering the substantial command issues that Vargas has shown not only in 2023 but throughout his professional career — he’s walked 11.5% of opponents in his overall minor league career — he’s clearly something of a project. That said, he’s also controllable for at least six seasons and still has a minor league option remaining for the 2024 campaign. The Mariners could see this as a similar bet to the one they made on Andres Munoz, who was a similarly live-armed but unproven young reliever with command issues when they picked him up from the Padres.

As it stands, the subtraction of Suarez still weakens the Seattle roster overall, so if there’s no subsequent move to add another third base option or at least to reallocate the $13MM in savings, this will still be widely viewed as a salary dump — even if there’s some legitimate long-term potential with Vargas. But the offseason is also quite young, and both the free-agent and trade markets have various options to consider at the hot corner or at second base, if Seattle is comfortable sliding another former Diamondback, Josh Rojas, over to third base.

A deal for Matt Chapman would be wildly uncharacteristic for Dipoto, who hasn’t signed a free-agent hitter to a multi-year deal since taking the reins in Seattle, but the market offers some more affordable options such as Gio Urshela and Justin Turner. The trade market is light on pure third basemen but has several shortstops, second basemen and/or multi-position names who could fit into the Seattle infield: Willy Adames, Jonathan India, Jorge Polanco, Kyle Farmer and perhaps Brendan Donovan among them.

Given the strong young core in Seattle and this past season’s narrow miss of the playoffs, there’s little reason to think the team is preparing for a notable step back. Dipoto has made a name for himself as perhaps the most active baseball operations leader in the game when it comes to the trade market, and is stands to reason that further moves will follow. With Suarez in Arizona, the M’s now project for a payroll around $133MM, per Roster Resource, which is about $7MM shy of last year’s total and about $25MM shy of their franchise record. There should be resources to further augment the roster in the days and weeks ahead.

USA Today’s Bob Nightengale first reported that the Mariners and D-backs had agreed to a trade involving Zavala and other players. Ryan Divish of the Seattle Times broke the news that Suarez and Vargas were in the swap.
