Angels looking to trade Dan Haren, Ervin Santana

The Los Angeles Angels' trade for Zack Greinke is having ripple effects on free agency -- and we're not even 48 hours into baseball's offseason.

According to CBS Sports' Jon Heyman, the Angels are looking to trade starting pitchers Dan Haren and Ervin Santana before a decision on their contract options must be made. In other words, the Angels are desperately looking to cash in either Haren or Santana for any type of asset, before they inevitably decline the 2013 options on both pitchers.

Declining the options on Haren and Santana would give the Angels more money to offer Greinke. Greinke is clearly the top arm on the market this year, and the Angels will likely face stiff competition from other teams for Greinke's services.

Haren's 2012 campaign was perhaps the worst of his career -- and easily the worst he's put together as a member of the Angels. Haren made 30 starts, and went 12-13 with a 1.29 WHIP and 4.33 ERA, while striking out 142 in 176 and 2/3 innings of work.

Haren's 2013 option is worth $15.5 million, and it's almost certain the Angels will decline it. Haren has also pitched for the St. Louis Cardinals, Oakland Athletics and Arizona Diamondbacks, and he shouldn't have too difficult of a time finding work.

Santana, like Haren, had a poor year in 2012. Also like Haren, Santana made 30 starts, and pitched to the tune of a 1.27 WHIP and 5.16 ERA. Though he held opposing hitters to a .239 average, Santana surrendered a staggering 39 home runs in 178 innings.

Santana's option is worth $13 million. The Angels have until Thursday to decide whether or not to bring Haren and Santana back for the 2013 season.
