Zumaya is tied for the American League lead among relievers with 12 innings pitched. His fastball is sitting at 98 mph and missing bats -- he had three strikeouts swinging Saturday, including one by Josh Hamilton.
"Oh yeah," Gerald Laird said. "He looks great."
Zumaya was unavailable Sunday after throwing two innings as manager Jim Leyland emphasizes taking care of everyone in the bullpen early in the season, especially his relievers coming back from injuries.
Zumaya hasn't pitched in back-to-back games this season, but that's more because he's had several multiple-inning outings.
