Narrative:
During cruise flight we were filed stl 352 degree radial to bayli then the bdf 3 arrival to ord. The STAR is easy to misread by looking at it. It looks like bayli is the 219 degree radial from bdf, which it is after bayli. However, you must first fly to bayli. The first officer set 039 degree course in his HSI. The GPS turned left. We expected a right turn, so I turned to the right. Directed the first officer to check both bayli in the GPS and verify the course on the chart. We went approximately 8 mi to the right of course. As soon as we realized our mistake, I directed the first officer to call center and tell them that we turned towards bdf. She gave us a vector and appeared to have no problem with us. What I learned from this is not to become complacent. Normally, I doublechk the route myself. Today I relied on the copilot.
