Arenado (intercostal) remains out of the lineup for Tuesday's game in Boston.
Arenado is dealing with a minor left intercostal injury and will miss a second straight start. The Diamondbacks are optimistic he will be able to avoid the injured list, but with a team off day looming Thursday, it's possible Arenado will be held out until the club returns home Friday. Jose Fernandez will occupy third base for Arizona on Tuesday.
