The Reds filled their 40-man roster by adding P Amir Garrett and OF Kyle Waldrop to their 40-man roster. (C. Trent Rosecrans) Garrett and Waldrop were ranked the #11 and #12 minor league prospects for the Reds by Kiley McDaniel this week’s story at FanGraphs. Doug Gray nailed this in a post at his site earlier this week. He described the addition of Garrett and Waldrop as a lock. Doug has Garrett ranked #7 and Waldrop #14 in the Reds organization. Tom Nichols wrote about Garrett in his Dayton Dragons review.

Tonight at midnight is the deadline for teams to add players to their 40-man roster to protect them from being selected in next month’s Rule 5 draft. Players selected in the Rule 5 draft must remain on a major league roster for a year, otherwise they must be returned to their original club.

Josh Hamilton’s selection in 2006 is considered the most successful example of a Rule 5 draft. The Chicago Cubs selected Hamilton from the Tampa Bay Devil Rays then traded him to the Reds for cash that same day. Hamilton hit .292/.368/.554 for the Reds in 337 plate appearances. The Reds traded him to the Texas Rangers for Edinson Volquez the next season. Hamilton was named the AL MVP for the Rangers in 2010 and three Silver Slugger awards over 5 years.
