Best known as one of the players the Red Sox got from the White Sox in return for Kevin Youkilis back in June, right-hander Zach Stewart was traded to the Pirates on Wednesday.

The Red Sox will receive a player to be named for Stewart, whom they designated for assignment last week.

After stints with the Reds (Minor Leagues only), Blue Jays, White Sox and Red Sox, the 26-year-old Stewart hopes to finally live up to some of his promise in Pittsburgh.

Scouts have seen potential in Stewart over the years, based on the fact he has been traded for Scott Rolen, Edwin Jackson and Youkilis in his career.

Following the trade to the Red Sox, Stewart spent most of his time in Boston's organization with Triple-A Pawtucket and pitched well at that level.

But the right-hander was shelled in two starts for the Red Sox, going 0-2 with a 22.24 ERA and giving up 17 hits in 5 2/3 innings.
