A college teammate of my son's played indy ball after graduation. He was very low side pitcher, hoping to get picked up. However, he only got traded to another indy team. He played one season.
One of son's HS teammates, an UDFA, is playing indy ball after being released from AAA. He is a LHP. Two seasons of Indy ball after a season in Mexico.
keewartson was offered by a half dozen teams after his release this spring. His reasoning was, after playing AAA ball, what is the point? Plus, he wasn't a pitcher.
Some MLB players that are released play indy ball hoping to get picked back up. Many seem to be foreign players without many other options. Or at least they play until they can figure it out.
Rightly or wrongly....it does prolong the dream. The player needs to know if they are just the supporting cast to the pitchers.
