What happened: Marte traveled to Phoenix for tests on his left knee after missing a game in Boston. The second baseman had been placed on the restricted list following that absence.

Why it matters: The move removes a veteran slugger from Arizona's lineup during its postseason push. The Diamondbacks are fighting the San Diego Padres for the final National League wild-card spot.

What to watch: Arizona's next update will center on Marte's readiness to rejoin the lineup.
