no. 1. "burke is the future" is not an absolute; 2. when you're struggling to score runs for a very good pitching staff, you don't take a guy like Biggio out of the lineup. not with the way he's hitting.
Re: Chris Burke. He hit .300 in AAA in 2003, stole 34 bases, and had 34 extra-base hits. He was the Round Rock MVP that year. Last season he was the PCL ROY, the PCL All-Star 2B, and for the first time he demonstrated home run power, hitting 16 HRs to go with 37 steals, and he got on base 40% of the time. Burke was dominant last year at AAA. Now that doesn't mean he's going to succeed at the ML level. All prospects have risks. But he's undeniably the Astros best prospect, and smart organizations find a way to play their best prospects, or trade them when they have value. Letting a 25-year-old 2B who dominated at AAA last season linger at AAA is just wasteful of talent.
