The Toronto Blue Jays continued to build up their pitching depth Saturday by re-acquiring left-hander Zach Jackson from the Cleveland Indians for a player to be named.

Jackson was chosen in the first round of the 2004 draft by the Blue Jays, who dealt him in the fall of 2005 to the Milwaukee Brewers as part of a package for first baseman Lyle Overbay.

The 26-year-old was later one of four players acquired by Cleveland in the 2008 trade that sent ace CC Sabathia to Milwaukee.

He pitched in three games, one start, for the Indians last season, posting a 9.35 earned-run average in 8 2-3 innings. At triple-A Columbus, he went 4-8 with a 6.05 ERA, made 14 starts and pitched in 30 games.

Jackson went 2-3 with a 5.60 ERA for Cleveland in 2008.

The Blue Jays will invite Jackson to spring training.
