The Houston Astros are said by sources to be meeting in Texas with star free agent pitcher Yu Darvish, following by one day the Cubs’ meeting with the right-hander. The Cubs’ confab with Darvish “went well” by all accounts. But they obviously have some company in the Darvish derby. The Twins, Astros and a couple others have interest in Darvish, though it isn’t known yet to what extent anyone will go. His old Rangers team is thought to be monitoring the situation, at least, while the Mariners and Phillies are among other teams being linked to Darvish, at least speculatively. Darvish and Jake Arrieta, the Cubs’ free agent, are the top two free agent starters. The market has developed slowly for almost all of the best free agents, with only Carlos Santana to this point exceeding the $50 million barrier, with his $60 million, three-year agreement with the Phillies. It’s reasonable to think Darvish and Arrieta would be looking at the $175 million, seven-year deal for Stephen Strasburg as a possible comp for them. Darvish took to social media to say he had a “very good meeting” with Cubs people Monday in Dallas, via the twitter translation. There’s a belief that the Astros may have a meeting set up with Darvish soon, too, and though that is unconfirmed, it would make sense for this week since Darvish’s agent Joel Wolfe was in Dallas, where Darvish lives, for the Cubs meeting.
