The last report was as of May 17th. At that point he was throwing bullpens. Think of this as spring training, as Hansen had none. Those guys go six weeks before they ramp up to game shape. We are at 3-4 weeks. Hold the panic for another couple of weeks at least.
I know the name Tommy Herr was mentioned earlier. If you add some BA points and walks to adjust for the era, that really is an interesting comp, especially when you focus on his peak in the mid 80's.
