Heyman On Penny, Atkins, Dye, Nationals

Jon Heyman of SI.com reports that the Giants appear to have a good chance of signing Brad Penny if he clears waivers today. Here are the rest of Heyman's rumors:

• The Rockies could non-tender Garrett Atkins after the season. He'd be in line for at least $7MM and the team may decide to spend that money elsewhere.
• The White Sox are expected to want to pick up Jermaine Dye's $12MM mutual option for 2010, but Dye could turn it down and try the free agent market instead. Given the relatively small contracts Adam Dunn and Bobby Abreu signed after last season and the competition Dye would face on the market, there's no guarantee Dye would make more than $12MM. Matt Holliday, Jason Bay and Johnny Damon will all hit free agency after the season. 
• The Nationals are expected to replace Jim Riggleman with a new field manager next year.
