PHOENIX -- Catcher Chris Snyder is on the verge of finalizing a three-year contract extension with the D-backs, and Brandon Webb could not be happier for his teammate and close friend.

Snyder, who will turn 28 on Feb. 12, hit .237 with 16 homers and 64 RBIs in 2008. His OPS+, which is a weighted form of on-base percentage plus slugging, was 103, meaning he was three percent above average offensively.

"Having 'Snydes' behind the plate for the next two years will be great," said Webb, who is under contract through next season with an option for 2010.

While Snyder's offense has improved, it's his work defensively that makes him a favorite among pitchers.

"'Snydes' has a good idea of what he is doing back there," Webb said. "He studies the hitters a lot and can adjust with them as the game goes along. As for the team, I am sure they feel the same way. I think everybody likes having 'Snydes' back there calling the game and feel very comfortable with him."

A baseball source said late last week that the final details were being worked out and Snyder would then take a physical before the contract is signed.

D-backs officials declined to comment.
