The hope is Chacin's right shoulder-biceps issue is not serious enough for the Rockies to need to make a signing. The official said the club reached out to Santana early in the free-agency process, but it backed away and does not have renewed interest for several reasons.
The Rockies went into last winter looking to keep the payroll at around $95 million and are up against that figure now. Additionally, the Rockies value Draft picks and would have to give up one to sign Santana, who turned down a qualifying offer from his former team, the Royals, that would have given him $14 million for one year.
Santana has the high strikeout-to-walk ratio the Rockies like, but he also gives up fly balls and home runs -- an American League-leading 39 with the Angels in 2012 and 26 last season. That was one of the reasons the Rockies went in a different direction for starting pitching -- trading with the Athletics for lefty Brett Anderson -- during the offseason.
