Jackson exits with finger cramp

Winless Rays righty leaves one out shy of potential victory

PHOENIX -- Rays right-hander Edwin Jackson had to leave Monday night's game against the Diamondbacks with two outs in the fifth inning with cramping and fatigue in his right index finger tendon.

After getting strike two on Chad Tracy, Jackson began to shake his right hand as if something wasn't right. Rays manager Joe Maddon and head trainer Ron Porterfield made their way to the mound. After some lively discussion, Jackson handed over the ball.

Jason Hammel took over for Jackson, who is listed as day-to-day.
