The Red Sox have been engaged in ongoing discussions with right-hander Dan Wheeler about the possibility of coming to Boston, according to sources familiar with the talks. While no deal is done at this time, one source proclaimed optimism about the direction of negotiations.

The 33-year-old free agent, who was drafted out of Pilgrim High School in Warwick (R.I.), has been with the Tampa Bay Rays since the middle of the 2007 season, when he was acquired from the Astros in a trade for Ty Wigginton. Wheeler had a 3.35 ERA in 48 1/3 innings in 2010, and he struck out 8.6 batters per nine innings. However, his innings total was the lowest of his professional career, and he has seen his workload go down in each of the last three years. Over his last three full seasons with the Rays, he has a 3.24 ERA while striking out 7.5 batters per nine innings, while walking 2.5 batters per nine.

Wheeler has appeared in 21 postseason games for the Rays and Astros, forging a 3.38 ERA while striking out 28 and walking eight in 26 2/3 innings. He was drafted in the 34th round by the Rays in 1996, and has since spent time with the Braves, Mets and Astros organizations before returning to Tampa Bay.

The Rays declined a $4 million option for his services for the 2011 season, instead opting to pay a $1 million buyout. The Rays also declined to offer the veteran salary arbitration. He earned $3.5 million last season in the final year of a three-year, $10.5 million deal he signed with the Rays prior to the 2008 season.
