Dean Kremer pitched six shutout innings, Anthony Santander hit his third career grand slam and the Baltimore Orioles completed a three-game series sweep of the Cincinnati Reds with an 11-1 victory Sunday. Jordan Westburg hit a two-run homer and Ryan McKenna added a solo shot for the Orioles, who have won four straight games and six of their last seven. Kremer (3-2) retired the first 13 batters he faced until Christian Encarnacion-Strand singled with one out in the fifth. The Reds managed only one hit and a walk in Kremer's six innings.
