Houston, TX (Sports Network) - Cincinnati Reds outfielder Ken Griffey Jr. left Monday's game against the Houston Astros with stiffness in his right hamstring.
Griffey was removed in the third inning after striking out against Houston starter Roy Oswalt. He is day-to-day.
Jason Romano replaced Griffey in the lineup.
Griffey, 34, already missed the first two games of the season with a strained right calf.
He has been injured most of the last four seasons. He tore a hamstring in spring training of 2001, and missed most of 2002 with a torn tendon in his knee. Last season, he dislocated his shoulder in the first week of action. He has not played in more than 111 games in a season since 2000, which was his first year with the Reds.
Griffey is batting .228 with three homers and 14 RBI in 22 games this season.
