The Seattle Mariners made a pair of trades on Friday as the team continues to augment their roster in preparation for the 2017 season.

The Mariners dealt outfielder Seth Smith to the Baltimore Orioles in exchange for right-handed pitcher Yovani Gallardo. Seattle then traded right-handed pitcher Nathan Karns to the Kansas City Royals for outfielder Jarrod Dyson.

Gallardo gives Seattle a more accomplished starting pitcher to add to their rotation while Dyson adds another defensively skilled outfielder to the roster.

Gallardo, 30, went 6-8 with a 5.42 ERA (71 ER, 118.0 IP) with 85 strikeouts and 61 walks in 23 starts with Baltimore last season.

General manager Jerry Dipoto is expecting a rebound season from Gallardo with a bigger ballpark in Safeco Field and a better defensive outfield behind him helping supplement his skills.

"He's a competitor. He wants to pitch. He wants to be out there when it matters," Dipoto said. "If his track record shows us anything it's that when he is capable of taking the ball, he will go out and compete. The defense should help. The veteran stability will really bring something to the table for us."

Adding Gallardo to the rotation gave Dipoto the flexibility needed to complete the trade for Dyson.

"Once we brought Gallardo on board we felt a little bit more confident in our ability to move Nate, and that was the piece that was going to get Jarrod done," Dipoto said.

Dyson, 32, hit .278 with 46 runs, 14 doubles, 8 triples, 1 home run, 25 RBI and 30 stolen bases in 107 games with the Royals.

"Jarrod brings us a winning pedigree, along with elite level defense and base running," Dipoto said. "He joins players like Leonys Martin and Jean Segura in creating a disruptive element on the bases to our offensive game, while also enhancing our ability to prevent runs on defense."

Dipoto said Dyson now gives Seattle five separate players capable of playing center field that will greatly improve the defensive prowess of their outfield. Dyson joins Martin, Mitch Haniger, Ben Gamel and Guillermo Heredia as Seattle's leading outfield candidates.

It also allows Nelson Cruz to transition to a more full-time designated hitter role.

Dipoto said the team still has flexibility to add more to their pitching staff but that offensive roster is largely set.

"The likelihood of us doing anything more on the offensive side is remote," Dipoto said.
