Duke was hit Saturday night by a line drive off the bat of Colorado's Charlie Blackmon.
"It was very sensitive in the area, but I'm kind of surprised there's two broken bones in there," Duke told Nick Piecoro of the Arizona Republic. "I'm going to shoot for as short a recovery as possible. The bones will tell me how much time it's going to take. The doctor wanted me to have X-rays each week to keep track of how it's healing. I'm going to be optimistic for sure."
Duke had a 7.88 ERA in four appearances this spring, allowing 18 hits, eight runs and seven earned runs in eight innings this spring. Enright has given up two runs on five hits in nine innings this spring. Enright's walked just one batter while striking out five.
