The Seattle Mariners have selected infielder Brad Miller from Triple-A Tacoma and put him in the starting lineup for his major league debut Friday night against the Chicago Cubs.
Seattle also optioned infielder Carlos Triunfel to Tacoma and designated infielder Alex Liddi for assignment.
Miller was in the ninth spot in the lineup. He was on a 22-game hitting streak or Tacoma, hitting .356 with six home runs and 28 RBI in 26 games after starting the year with Double-A Jackson.
''He's been playing fantastic in Triple-A, and he made a good impression on us in spring training,'' Seattle manager Eric Wedge said. ''It's a good time to take a look at him.''
Triunfel was 2 for 24 in nine games and Liddi 1 for 17 in eight games.
