SEATTLE -- After stocking up on bullpen help the past four days, Mariners general manager Jerry Dipoto moved to bolster his team's offense for the postseason run by acquiring veteran center fielder Cameron Maybin from the Marlins just prior to Tuesday's 1 p.m. PT non-waiver Trade Deadline.
The Mariners sent Minor League infielder Bryson Brigman as well as $250,000 in this year's international bonus pool slot money to Miami to land the 31-year-old outfielder.
Maybin has posted a .251/.338/.343 slash line with three home runs and 20 RBIs in 99 games for the Marlins, who signed him for $3.25 million as a free agent last offseason. To make room on the 40-man roster, Seattle moved reliever Dan Altavilla from the 10-day to the 60-day disabled list.
"We're excited to get Cam," said Dipoto. "He's experienced, the energy he brings, he gives us another athlete, a runner who adds to the way we play and can start pushing the envelope a little bit. Over this last month or so he's been in a really good place offensively.
"He's played a really strong center field this year, and we know he's multi-position capable. He fits into the theme of what we're doing and I think adds better balance to our club. And the experience of a guy who's been through it for as long as Cam has doesn't hurt."
The 12-year-veteran is a career .255/.323/.369 hitter who is regarded as a solid defender. Guillermo Heredia has been handling most of Seattle's center-field duties since Dee Gordon shifted back to second base following Robinson Cano's 80-game suspension.
Heredia is a very good defender, but he has hit just .229/.314/.335 with four homers and 14 RBIs in 90 games. Since June 1, Heredia's line is .180/.231/.271 in 49 games. Maybin has posted a .263/.358/.364 line in 46 games over the same span.
Both Dipoto and manager Scott Servais indicated Heredia would continue playing a role on the team and is an excellent defender in left field as well as center, which might indicate that left fielder Ben Gamel will be the odd man out until rosters can be expanded in September.
"Guillermo is an unbelievable left fielder and done a nice job in center as well," Servais said. "Denard Span and [Mitch] Haniger are still a big part of things. Gamel will be used sparingly. That's how we see it."
Both Heredia and Gamel have Minor League options and neither has Maybin's experience. Span, acquired in a May trade from the Rays, has been playing well in left field and recently moved into the No. 3 spot in the order.
Maybin will hit near the bottom of the order, while adding some speed.
"Cam has a pretty good history of getting on base," Dipoto said. "He works counts. He does make an impact on the bases. And I don't think renders Guillermo moot on our roster. He's a good player, but we've asked Guillermo to do something outside of his skillset and Cam can help that and maybe put Guillermo in a position to where he can impact the game in the ways he was doing before we asked him to play every day."
Maybin won a World Series ring with the Astros last season after being claimed off waivers from the Angels for the final month of the regular season.
Brigman is the Mariners' No. 19 prospect, per MLB Pipeline. A third-round Draft pick out of San Diego in 2016, the 23-year-old is hitting .304 with two homers and 38 RBIs in 98 games for Class A Advanced Modesto.
The trade is Dipoto's fourth in the past five days, having previously acquired reliever Sam Tuivailala from the Cardinals, Zach Duke from the Twins and Adam Warren from the Yankees.
The Mariners are three games back of the Astros in the American League West and two ahead of the A's for the second AL Wild Card spot entering play Tuesday as they pursue their first postseason berth since 2001.
