Akinori Iwamura
He made his first Major League start of the year that night against the Cincinnati Reds, playing at third base. He hit an RBI double in the 8th inning off Reds starter Mike Leake. But his role on the team was initially in question, as Andy LaRoche had been the Pirates every day third baseman. With starting second baseman Akinori Iwamura struggling, Pirates manager John Russell played Walker at second base – a position where he had only played 23 career games at any level. He hit his first Major League home run on June 1, 2010 off Chicago Cubs starter Ted Lilly.
