To advance more runs, when your playing a CPU player and you hit a fair ball, keep taping L1 when you get to 1st Base (that make you go to 2nd Base). The 1st baseman will throw it to 2nd.

When you are almost at 2nd press R1 to go back to 1st. The second baseman will throw it to first. Then, you should press L1 right before you get to 1st. When at second, press L1 to go to 3rd. Press R1 to go back to 2nd while the 1st baseman throws it ti the 3rd baseman. Do the L1 and R1 procedures until you score a inside the park homerun.
