Marte, who was placed on the restricted list Monday, didn't report to Fenway Park ahead of the Diamondbacks' game against the Red Sox due to a personal matter and is being considered day-to-day, Francys Romero of BeisbolFR.com reports.
Marte's situation remains murky, and the Diamondbacks have yet to comment when the three-time All-Star might return to the team or whether he'll face any kind of discipline after he had been expected to play Monday. Ildemaro Vargas started at second base in the series opener in Boston and would be in store for more playing time if Marte misses additional games.
