The Red Sox have designated outfielder/first baseman Daniel Nava for assignment, Alex Speier of the Boston Globe reports on Twitter. He lost as spot as the club moved to add bullpen depth to its active roster.

Nava, 32, put up strong results in fairly extensive playing time over each of the last three seasons, racking up 1,261 plate appearances with a .278/.364/.403 slash. But injuries and performance issues have kept him grounded in 2015. He’s put up a meager .152/.260/.182 line in only 78 turns at bat.

Despite the recent struggles, it wouldn’t be surprised to hear of another team with interest at giving Nava a bench spot. But his $1.85MM salary is a major obstacle, so it will take some effort for Boston to find him a new home. (Otherwise, he’ll likely clear waivers and remain under team control.)
