The Mariners Outfield, Now With Cameron Maybin
Earlier this afternoon, the Mariners acquired Cameron Maybin from the Marlins for infield prospect Bryson Brigman and international slot money. This isn’t an especially big trade, but it might end up being an important one for Seattle, who, at this very moment, is just two games ahead of the A’s for the second AL wild card spot.
If we were inclined to be charitable, we might say that center field hasn’t been a strength for the Mariners this season. The nastier sorts among us might describe the play there as having been lousy. The collection of players Seattle has run out rank 20th at the position in team WAR, and the defense has been worse, checking in at 24th. Some of that is the result of the short-lived Dee Gordon, Center Fielder experiment, but the trouble hasn’t stopped there. Guillermo Heredia is a useful fourth outfielder, but he has been exposed since being pressed into more regular service with Gordon’s shift back to the infield. He’s mustered a meager .229/.314/.335 slash line and an 85 wRC+, and even that is buoyed by a hot April and May. He is oddly performing better against righties than lefties but not doing well against either. And in what is admittedly a limited 90-game sample, he hasn’t been the sort of defensive standout whose play in the field compensates for his struggles at the plate.
With the trade, the Mariners outfield shifts some. Maybin, who has been a plus defender before and grades well now, will slot into center, with Mitch Haniger shifting back to right field and some combination of Denard Span and Ben Gamel playing in left.
Maybin may not represent a huge offensive upgrade (his season slash line of .251/.338/.343 and wRC+ of 91 aren’t All-Star level, though July has gone better with a 148 wRC+), but the slightly better bat and more-than-slightly better defense constitute a definite improvement. Haniger can play a capable enough center field, and he may still play there on occasion, but acquiring Maybin allows the Mariners to keep Gordon at second base (Robinson Cano is slated to assume first base duties when he returns from his PED suspension) and give Heredia a breather on the bench or in Tacoma.
For that, the Mariners give up slot money and Brigman, who Eric Longenhagen described thusly:
Bryson Brigman is a 2B w/ long track record of making contact, dating back to high-level high school and college showcases/national teams. Lack of physicality/power have been the issue in pro ball. Stats are up this year, but in Cal League. Batted ball profile hasn't shifted.

Acquiring Maybin is something of a marginal trade, but the AL postseason picture seems likely to be decided at the margins. In that respect, it might end up mattering quite a bit.
