When the international signing period began on July 2, the Giants announced the signing of Dominican righthander Luis Mateo with a formal press release. The bonus was $625,000, which ranked as one of the top 20 bonuses of this year’s international signing period.

However, the Giants had the contract voided in August once they found bone chips in his elbow, according to Mateo’s agent, Greg Maroni of California Sports Management. Mateo was evaluated in September by Dr. Lewis Yocum, who saw no need for surgery in Mateo’s elbow or shoulder and felt that aggressive rehab would be the preferred course of action, according to Maroni. The Giants did not respond to several calls in the past week seeking comment. Major League Baseball declined to comment on the issue.

Mateo is a projectable 6-foot-3, 175-pound righthander with good arm speed. He has worked out with several teams since becoming a free agent again.
