Greinke sharp in bullpen session

GLENDALE, Ariz. -- Zack Greinke, who missed Sunday's bullpen session with minor forearm tightness and missed a Wednesday start because of the flu, threw an impressive bullpen session Friday with no discomfort from either.

As two athletic trainers and pitching coach Rick Honeycutt watched and manager Don Mattingly stood in both batter's boxes, Greinke threw all of his pitches under the roof of the batting cage with solid command and reported no problems.

"It felt good," he said. "I feel a lot better after being sick earlier in the week. I'm good to have my workout now."

Greinke clearly was more affected by the flu than the arm stiffness, although the management that signed him to a $147 million contract was holding its breath.

"It's really nothing serious," he said. "It's just something I deal with sometimes in Spring Training, and sometimes during the season."

Greinke was pleased with the command of all of his pitches and Mattingly shook his head approvingly at the nastier ones. Greinke said feedback from a former batting champ like Mattingly is helpful, to a point.

"Now I want to see how the hitters respond in the game," said Greinke. "In the 'pen, everything can feel sharp. Sometimes in the 'pen it looks really good, but the hitters can tell you it's not as good as you think. Other times you feel that it's not as good, but to the hitters it's not easy to see."
