The Detroit Tigers have given consideration to cleaning house, and the San Francisco Giants have interest in one of their players.

MLB Network’s Jon Morosi says the Giants are interested in Justin Upton, whom the Tigers are considering trading.

As Morosi says, the issue is that Upton has an opt-out clause he could exercise after the season. Upton signed a six-year, $132.75 million deal with the Tigers prior to last season. The former No. 1 pick is enjoying one of the best seasons of his career, as he has 28 home runs and a .913 OPS this season.
