Outfielder Andrew Lopez, who hit .256 with four home runs and 27 RBIs at Class-A Princeton, and right-handed pitcher Gregory Reinhard, who went 6-10 for Class-A Southwest Michigan, were acquired for Ryu, who briefly pitched for the Cubs last season.

Lopez was an eighth round selection in the 2005 draft, while Reinhard was selected in the sixth round of the same draft. The Cubs had to pare the roster down to 40 by the start of camp, after being one man over due to the addition of Notre Dame pitcher Jeff Samardzija last month.

Ryu is 36-28 with a 3.42 ERA in 118 minor league games, and was 0-1 with an 8.40 ERA in his brief stint with the Cubs last summer.

A graduate of Elk Grove (Calif.) High School, Lopez batted .325 (39-for-120) in 34 games with Princeton in 2005.

Reinhard, 23, was Tampa Bay's sixth-round selection in the 2005 draft. His 142.0 innings pitched and 134 strikeouts each ranked third on the Single-A Southwest Michigan's pitching staff in 2006. A native of Marinette, Wis., he posted a 5-3 record with a 3.52 ERA (31 ER/79.1 IP) in 14 home starts while going 1-7 with a 5.74 ERA (40 ER/62.2 IP) in 13 road games (12 starts).

Reinhard, who attended the University of Wisconsin-Whitewater, set the school record with 19 strikeouts against the University of Wisconsin-Stout on April 17, 2005.
