In the playoff mix for a second straight year, the Baltimore Orioles made the biggest move on a quiet trade-deadline day, acquiring Bud Norris to keep pace with the Boston Red Sox. Hoping to catch the NL West-leading Dodgers, the Arizona Diamondbacks filled a hole in their bullpen Wednesday by sending struggling 20-game winner Ian Kennedy to San Diego for lefty reliever Joe Thatcher. Boston put the pressure on Baltimore by picking up 2007 NL Cy Young Award winner Jake Peavy from the Chicago White Sox less than 24 hours earlier in a three-team trade.
