Oakland manager Mark Kotsay said Ruiz will make the team's Opening Day roster, Martin Gallegos of MLB.com reports.
Advice: After being traded from Milwaukee to Oakland over the offseason, Ruiz will officially get another chance to contribute in the majors. The 24-year-old outfield prospect recorded just a .452 OPS in the majors last season, but has demonstrated a knack for stealing bases at a consistent rate. It is still uncertain whether Ruiz or Cristian Pache will get the nod as the A's starting center fielder.
