Rumors that Phillies current ace Cole Hamels could be headed to the Cubs gained credence when it was revealed that the latter is on his approved trade list, sources have told ESPN baseball analyst Jayson Stark.

Hamels was claimed by the Cubs when the Phillies tested out interest by placing him on waivers, leading to speculation that the two teams could be trade partners. Hamels has been torrid for two months with four wins in his last six starts and 12 quality starts in his last 13 outings. He has surrendered just 15 earned runs in his last 92 2/3 innings pitched since June 1.
