Last Aug. 13 -- same Citizens Bank Park, same Phillies -- Rusin replaced Tyler Chatwood, who suffered a back injury, and held the Phillies scoreless for three innings. Chatwood struggled before leaving and the Rockies lost, but Rusin at least held them close.
Gray originally suffered his injury in Spring Training and he aggravated it in the second inning. Gray stayed in through the third and into the fourth, which at least gave Rusin time to prepare.
"Once they told me he came up slow after that one ground ball he fielded, I was stretched and ready to go," Rusin said. "I knew I had to eat up innings and get outs as quickly as possible. I was able to do that."
Rusin needed just 37 pitches to get the game into the seventh inning, from which point the strong back of the Rockies bullpen could assure victory.
