Max Scherzer was encouraged by a pain-free bullpen session on Wednesday.

"Finally," he shouted twice after the workout in St. Petersburg, Fla.

The Texas Rangers won their American League Wild Card Series against the Tampa Bay Rays without the 39-year-old ace, sweeping the best-of-three set.

Scherzer has not pitched in a game since straining the teres major muscle in his right shoulder on Sept. 12.

"Last week was a light bullpen, this one was for real," he said. "I was able to step on it more. And it was pain free."

The progress is encouraging but it remains a long shot for Scherzer to return for the ALDS.
