The Angels are expected to make at least one trade this week.

They are aggressively trying to move Dan Haren and Ervin Santana before having to decide on their 2013 options, according to Major League sources.

"I think they trade both guys," one rival executive said.

Los Angeles will not exercise Santana's $13 million option, a source said, and there is every indication that they will decline Haren's $15.5 million option as well.
