The 5-foot-9, 140-pound Torreyes owns a career Minor League batting line of .312/.374/.449 and has only struck out 82 times in 1,443 plate appearances, giving him more walks (92) than strikeouts. Torreyes was originally acquired by the Cubs from the Reds, alongside left-hander Travis Wood and outfielder Dave Sappelt, in exchange for lefty Sean Marshall in December 2011.
The Astros had the largest international signing bonus pool this year before the trade, in which they shipped bonus slots No. 2 and 3 -- a total value of $784,700 -- to the Cubs, who entered Tuesday second with a $3,857,200 bonus pool.
Chicago quickly moved past Houston in terms of international slot money, bumping its total to $5,520,300 through three trades Tuesday.
The Cubs have been connected to several top international prospects. They agreed to terms with Venezuelan shortstop Gleyber Torres, MLB.com's No. 3 international prospect, on Tuesday. They have also been linked to 16-year-old outfielder Eloy Jimenez, the top overall prospect.
The Astros' total international signing pool, meanwhile, has dropped from $4,943,700 to $4,159,000, the third-highest figure in the Majors behind the Cubs and Rockies.
