Third baseman Kevin Youkilis was scratched from the lineup Tuesday before game time because of a sore right knee. He has been on a hitting tear of late, going 6-17 (.353) with three home runs and four runs scored in the last five games. He is hitting .409 (18-44) with five home runs and 16 RBI in 14 home games with the Sox since he was acquired from Boston on June 24.
Taking his place was Ray Olmedo, whose contract was purchased from Class AAA Charlotte on July 29. Veteran Olmedo has played in the majors before with Cincinnati (2003-06) and Toronto (2007).
