Don't know if it's an economy thing or a performance thing, but there are a number of tickets available for Opening Day on Stub Hub for less then $100. You can sit in upper deck infield box for $70, which is pretty good compared to recent years. (fyi, this is an affiliate link at Stub Hub)
The Tigers made some minor league cuts yesterday. Most surprising was Darwin De Leon who used to be known as Edward Reynoso. Regardless he was a Venezuelan Dominican lefty who could really pitch. Something besides performance likely led to this decision.
