Rojas went 2-for-4 with an RBI single, a double and two runs in a win over the Orioles on Friday.
The trade-deadline acquisition had received sparse opportunities and had yet to record a hit with the Mariners since arriving from the Diamondbacks, but that changed in a notable way Friday. Rojas, who has yet to leave the yard this season in 231 plate appearances, should have a chance to claim everyday playing time at second base and attempt to rediscover his mysteriously absent power stroke now that Kolten Wong has been jettisoned.
