text: what's the deal with biggio and burke at 2nd?  do they split time there? will it continue? astros no won't continue forever. burke was supposed to spell biggio & the ofers to the tune of 3-4 days a week. lamb is in so much cause he was hot filling in for berkman. he always gets that way with regular playing time at one position, so he'll cool off back to pinch hitting, where they need the strong lefty bat off the bench & burke will move around more with more playing time for both he & biggio.
