Through the end of April, Jorge Polanco was among the best players in baseball. Polanco is at least average thus far this month, however he has been instrumental in helping the slumping Mariners win their past two games against the visiting Cleveland Guardians. The teams will play the finale of the three-game series scheduled for Sunday afternoon in Seattle. Polanco’s bases-loaded single with two outs in the bottom of the ninth inning Saturday off Cleveland closer Emmanuel Clase helped the Mariners rally for a 4-3 victory.
