SEATTLE (AP) — The Mariners have activated left-hander Cliff Lee from the 15-day disabled list to make his long-awaited Seattle debut against Texas.

The Mariners' corresponding move before Friday night's game against the Rangers was optioning reliever Shawn Kelly to Triple-A Tacoma.

Lee has been out since he strained his abdomen during a spring training game on March 15.

The 2008 AL Cy Young Award winner says he's been pain-free for weeks. But Seattle's prized winter acquisition from Philadelphia dutifully followed the team's cautious rehabilitation plan for his third strained abdomen since 2003.

The 26-year-old Kelley has pitched in six games this season, with a win and a 2.57 ERA in seven innings.
