Edwin Jackson will be a bargain

When bargain hunting in the free-agent market, players represented by Scott Boras are probably not the first place a major league team should look. The super-agent is legendary for his epic brochures extolling his client's virtues -- he once produced a book comparing Oliver Perez to Sandy Koufax -- and for his success in getting teams to pay above and beyond what his players are expected to sign for. However, this year, Boras represents a player who has performed better than his overall reputation suggests, and who could turn out to provide terrific value for the team that ends up signing him.

That player is Edwin Jackson, the well-traveled 28-year-old starter who has already pitched for six teams in his career without finding a permanent home. Because Jackson reached the majors at age 19 and then struggled to live up to the billing of a top prospect, he's widely seen as an inconsistent underachiever who has never figured out how to harness his physical abilities.

Three years ago, that reputation was well deserved. From 2003 through 2008, Jackson threw 465 innings of pretty terrible baseball. He walked 11.1 percent of the batters he faced and posted a FIP that was 15 percent below average, putting him in the company of pitchers such as Casey Fossum and Eric Milton. After the 2008 season, the Tampa Bay Rays decided not to wait for his performance to match his stuff any longer and shipped him to the Detroit Tigers.

Since then, Jackson has been a different pitcher. He's dramatically cut his walk rate while simultaneously striking out batters with more frequency, and has produced results far beyond what he achieved earlier in his career.
