Dustin Pedroia has been in the heart of Boston's batting order during its strong start. His play was on the mind of San Diego manager Bud Black before the game. Pedroia hit a two-run double to jump-start Boston's 18-hit effort, David Ortiz had a two-run single and the Red Sox wrapped up a big homestand by beating San Diego 8-2 Thursday, sending the Padres to their season-high sixth straight loss.
