Jerry Dipoto Discusses Castillo, Lineup, Polanco

Mariners president of baseball operations Jerry Dipoto met with reporters this afternoon after the team finalized the one-year deal to retain Jorge Polanco. Seattle’s longtime front office leader addressed the team’s atypically quiet offseason while providing a couple injury updates.

Dipoto said the front office entered the winter believing they could be in for a slow offseason. “One of our points going into this offseason, and I know I made it sitting in the dugout in the final series, was that we didn’t anticipate a great deal of movement around the team,” he told the beat (including Ryan Divish of the Seattle Times). “As we are now about a week away from heading to Spring Training, I’d say that probably played out to be spot on, much to, I think, the dismay of a few. But we have a good team.”

Seattle has made two major league free agent signings. They brought Polanco back on a $7.75MM guarantee and added Donovan Solano as a part-time righty bat for $3.5MM. Reporting from both The Seattle Times and MLB.com throughout the offseason has suggested that ownership was only allowing the front office to allocate between $15MM-20MM to the MLB payroll. While the lack of free agent activity has certainly been a source of frustration for much of the fanbase, it’s not especially surprising.

The more interesting development has been the M’s willingness to sit out the trade market. They’ve made four trades this offseason, all of which have been depth acquisitions for players who were in DFA limbo: Austin Shenton, Miles Mastrobuoni, Blake Hunt and Will Klein. Those are akin to waiver claims. The Mariners essentially haven’t made a single notable move on the trade market, a stark contrast to Dipoto’s reputation as one of the game’s most prolific traders. The “Trader Jerry” nickname has been well earned in prior offseasons.

Most trade speculation concerned the possibility of the Mariners moving a starting pitcher to add a hitter. As Dipoto noted today, he did indeed downplay that notion before last season even ended. He famously called dealing from the rotation the M’s “Plan Z” for the offseason in the referenced media scrum. That didn’t stop other teams from inquiring on Seattle’s young rotation nucleus of George Kirby, Logan Gilbert, Bryce Miller and Bryan Woo, but there’s nothing to suggest the Mariners gave strong consideration to moving any of them.

The one starter who was available was Luis Castillo. The veteran righty is under contract for another three seasons and $68.25MM (plus a 2028 vesting option). Trading Castillo could have created spending room while netting the M’s immediate lineup help. It wasn’t going to be a straight salary dump, though, and Seattle hasn’t found an offer it finds compelling. The Seattle Times’ Adam Jude reported last week that Castillo was unlikely to move at this point.

Dipoto implied as much in today’s comments. He told Jude and other reporters that the front office received some proposals that warranted real consideration, but those obviously did not result in a deal. “Not shockingly, we had inquiries on all five of our starting pitchers and dozens of prospects along the way,” he added. “But obviously we opted not to go that route.” While he left open the possibility of making another move, he noted that the front office would be happy with the roster “if this is our team going into Spring Training or Opening Day” (via Divish and Jude).

The Mariners will go into Spring Training with arguably MLB’s best 1-5 in the rotation. Their depth behind that is lacking, though perhaps quick-moving prospect Logan Evans can soon be a factor. Seattle benefited from excellent rotation health last year. Woo was the only member of their front five who made fewer than 30 starts. That’ll be difficult to replicate, but when the rotation is at full strength, they’re giving the ball to an above-average starter every night.

As has long been the case, the question is whether they’ll score enough runs. Dipoto expressed confidence in the lineup, pointing to their success later in the season after the managerial and hitting coach changes. Seattle hitters had a .216/.301/.365 batting line through August 21. After dismissing Scott Servais and Jarret DeHart in favor of Dan Wilson and Edgar Martinez, respectively, they hit .255/.347/.417 in their final 34 games.

Attributing that entirely to the coaching changes is overly simplistic. They improved the lineup at the deadline with the Justin Turner and Randy Arozarena pickups and league-wide offense tends to peak later in the summer with warmer weather. Still, the change in voice probably played some part in the much improved finish. The Mariners play in the sport’s toughest home park for hitters. Only the White Sox had a lower team OPS in home games. Seattle ranked 13th in OPS on the road. Mike Petriello of MLB.com examined some reasons behind T-Mobile Park’s extreme pitcher-friendly environment last week in a column that’s well worth a full read.

Dipoto also addressed a few injury situations. He expressed confidence in Polanco’s health after the veteran infielder played through a left knee injury that eventually required a meniscus repair. The Mariners believe the move from his longtime second base position to third base will take less of a toll on him physically. Meanwhile, reliever Troy Taylor suffered a lat strain during his offseason workouts and will not be ready for the start of camp. It’s not clear if he’ll need to begin the regular season on the injured list. The righty turned in a 3.72 ERA while striking out nearly 31% of opposing hitters across 21 appearances as a rookie.
