Mason Tobin is happy to be here

ARLINGTON, Texas -- One of the surprises of the Rangers opening day roster is right handed reliever Mason Tobin's selection to the team.

Tobin was a long shot to make the club, considering he was coming back from Tommy John surgery and hadn't pitched beyond Class A.

But this spring, Tobin posted a 1.86 ERA in eight games.

"It hasn’t quite hit me yet," said Tobin, who the Rangers acquired at the Rule 5 Draft in December. "I'm pretty sure it will hit me when I get to run out on the field. I had no expectations. I didn’t expect to make the club, I knew I had the ability but I didn’t expect to make the club being where I came from and having no time over A ball. Besides spring training, I threw in big league games in spring training with the Angels and stuff like that."

When and if Tobin pitches it will be the first time he's entered a game in the major leagues. He pitched in 25 minor league games going 6-4 with a 2.43 ERA. But injuries slowed him down and he had Tommy John surgery in June 2009.

"For my first outing, I got into a game and when I was finished I felt nothing and it went all away," he said. "I wasn't worried about my health, I was healthy. Now I worry about just pitching."
