The Mariners have announced that they’ve outrighted lefty Lucas Luetge to Triple-A Tacoma. The Mariners’ 40-man roster now contains 39 players.

The 28-year-old Luetge was a relatively productive part of the Mariners’ bullpen in 2012 after they took him from the Brewers in the Rule 5 Draft. He also made 35 big-league appearances in 2013. Since then, though, he’s played sparingly at the Major League level and has struggled with walks in his infrequent appearances. He’s spent most of this season with Tacoma and hasn’t gotten great results, posting a 5.69 ERA, 6.8 K/9 and 4.2 BB/9 in 49 innings there. For his big-league career, Luetge has a 4.35 ERA, 7.5 K/9 and 4.8 BB/9 in 74 innings.
