Boston, MA (My Sportsbook) - The Boston Red Sox have reportedly agreed to a one-year contract with right-hander John Smoltz, who had spent his entire big league career with Atlanta.

A report on MLB.com stated that Smoltz called many of his teammates late Wednesday night to say goodbye and will inform the Braves of his decision on Thursday. The deal is said to be worth $5.5 million and could reach $10 million with incentives.

Smoltz is supposedly making tremendous progress following season-ending shoulder surgery. He went 3-2 last year for the Braves with a 2.57 earned run average in six games, five of which were starts.

As much progress as he has made, though, Smoltz, likely won't be able to pitch until at least June.

A late round pick of the Detroit Tigers way back in 1985, Smoltz was traded to Atlanta in 1987 and has pitched all 20 of his big league seasons with the Braves. The 41-year-old hurler had been with one team longer than any other current major leaguer.

The only pitcher in big league history with at least 200 wins and 150 saves, Smoltz spent the first 12 years of his career in Atlanta as a starter. However, he missed the entire 2000 season after undergoing Tommy John surgery, then returned in 2001 and spent most of the year as a closer.

Smoltz notched 154 saves from 2001 through 2004 before returning to the rotation for the 2005 campaign.

The 1996 Cy Young winner has a career mark of 210-147 in the regular season, and during his shortened 2008 season became the 16th pitcher to reach 3,000 strikeouts. He is also the winningest pitcher in postseason history with a record of 15-4.

Smoltz now joins a rotation that already includes Josh Beckett, Daisuke Matsuzaka, Jon Lester, Tim Wakefield and Brad Penny, whose deal is expected to be finalized this week.
