Jackson spent most of the 2009 season pitching for Triple-A Columbus, going 4-8 with a 6.05 ERA in 30 games (14 starts). He also appeared in three games for the Indians -- starting one -- and yielded nine earned runs in 8 2/3 innings (a 9.35 ERA).
The 26-year-old was taken No. 32 overall in '04 and has made 22 appearances (17 starts) spread out through three seasons with the Brewers and Indians, going 4-5 with a 5.81 ERA.
Jackson, mainly a pitch-to-contact guy, was the player to be named later in the deal that sent Lyle Overbay from the Brewers to the Blue Jays in December '05. He was then dealt to Cleveland as part of the trade that landed CC Sabathia in Milwaukee in July '08.
In six Minor League seasons, Jackson is 39-38 with a 4.38 ERA and has started 101 of his 138 games.
