To make room on the Major League, 40-man roster, outfielder Jeremy Reed was placed on the 60-day disabled list with a fractured right thumb.
Lowe, 23, posted a 1-2 record with six saves and 1.96 ERA in 24 games, two starts, combined between single-A Inland Empire and double-A San Antonio this season. In 46.0 innings, he struck out 60 batters, allowed just 14 runs, 10 earned, and held his opponents average to .187. Lowe started the season at Inland Empire and was on the disabled list from May 4-21 with a right shoulder strain. He was promoted to San Antonio June 3 and tossed 13.0 consecutive scoreless innings. Lowe was the Mariners' 5th round selection in the 2004 June draft.
