SEATTLE (AP) The Seattle Mariners optioned slumping first baseman Dae-Ho Lee to Triple-A Tacoma.

Seattle announced the roster move Friday before opening a three-game series against Milwaukee. The Mariners recalled Stefan Romero from Tacoma and put him in the starting lineup at first base against the Brewers.

Lee, a star in South Korea and Japan, was a revelation the first half of the season, earning his way into a regular platoon at first base. But he's been in a slump since the All-Star break, hitting just .109 with one home run and four RBIs in 20 games. Lee is hitless in his past 14 at-bats.
