Arnold Palmer still hitting balls, staying busy

Arnold Palmer didn't make a live television appearance at Bay Hill. For the first time, he didn't hit the ceremonial first tee shot at the Masters. He struggles with mobility, which kept him from attending the US Open.

Just don't get the idea Palmer is slowing down entirely.

The day after the US Open, he drove his golf cart up to the back entrance of his office across from Latrobe Country Club. The 86-year-old Palmer had just returned from hitting balls. And he was as frustrated as ever.
