Well, it's not a Cliff Lee signing nor a Zack Greinke trade, but they're Reds transactions just the same. From Baseball America:

Cincinnati Reds
Signed: OF David Cook, OF Welinton Ramirez

Corner outfielder David Cook has solid defensive tools and raw power, but he's spent much of his career at Double-A and is now 29. He slugged 25 homers for the ’09 Double-A Birmingham Barons in the White Sox system, and he's fared quite well against lefty pitchers in Double-A in the past two season (.840 OPS last year and .941 in ’09), suggesting some platoon possibilities if he makes his way to a big league bench.

Cook, by the way, is a native of Columbus. A ninth-round pick of the White Sox in 2003, he spent most of last season with Houston's AA affiliate in Corpus Christi where he went 11-36-.245/.337/.406. Cook swiped seven bases in nine tries. He also got 30 plate appearances in AAA.

Ramirez, 23, is from Azua, Dominican Republic, from where the Blue Jays signed him in 2006. He plays all three outfield positions, but mostly saw action in right last season. At High-A Dunedin, Ramirez went 9-49-.237/.271/.373 and stole 12 bags in 18 attempts.
