A tremendous homestand in which the Bucs blanked the Cards three in a row and outscored the Redbirds and Mets a combined 43-4 while winning six straight now looks in the rear-view mirror, as the Pirates turned into the Pirates again on Friday when on the road and blanked 6-0 in Seattle. Not sure how much Don Kelly can count upon Saturday starter Mike Burrows, whose efforts have encouraged but usually at a five-inning max. The Bucs' offense is always liable to go into a funk, and Luis Castillo is off of one of his better Mariner efforts, allowing just one run across 6 IP vs. the Rangers last Sunday in Seattle's 6-4 win (12 innings).
