Arizona Diamondbacks admit they have no idea what happened with star infielder: it's 'a complete mystery'

Arizona Diamondbacks second baseman Ketel Marte will be transferred to the 10-day injured list from the restricted list, three days after he failed to show up for a game in Boston.

Diamondbacks president Derrick Hall calls Ketel Marte's unexplained absence from Fenway Park a "mystery" and says the team still has no answers.
