Huff went 2-0 with a 1.32 ERA in Spring Training and was bitterly disappointed that his performance wasn't good enough to break with the Major League club.
"Not breaking with the team bummed me out a little. I thought I did everything I could," he said. "I knew there was talk about needing a starter for Tuesday. I couldn't concentrate on that. They have a method to their madness. They're smart; that's why they're in the positions they're in."
In his only appearance at Triple-A Oklahoma City on Thursday, Huff allowed one run in three innings of relief.
The starter of that game, right-hander Scott Baker, also was considered a candidate to make Tuesday night's start, but manager Don Mattingly preferred the matchup of Huff against Seattle's left-handed hitters.
