Angels outfielder Mike Trout is mourning the loss of his brother in law. Aaron Cox, the younger brother of Trout's wife, passed away early Wednesday morning at the age of 24. The news was confirmed in a statement by the team and the family, but a cause of death was not released. Cox played with the Angels' minor league organization in 2015. Trout was expected to come off the 10-day disabled list on August 16th, but he left the team earlier this week citing family reasons.
