Bartolo Colon is off to an excellent start, posting a 2.63 ERA in his first four starts. The right-hander threw 38 consecutive strikes for the Athletics this past week. He could be one of the most sought-after trade targets at midseason, and maybe sooner rather than later. Colon's base salary for this season is just $2 million, far less than some of the alternatives that will pop up on the market, and Oakland's front office is clearly devoted to the idea of building the team for 2015-16.
