Robertson earned a hold Saturday against the Marlins, allowing one hit in a scoreless seventh inning.
Robertson is already up to six holds through 10.2 innings this season. The veteran right-hander has offered a stabilizing presence to the Philadelphia bullpen since his arrival, registering a 2.53 ERA, 1.31 WHIP and 15:5 K:BB. If anything were to happen to closer Jhoan Duran down the stretch, Robertson has given the Phillies another capable arm with closing experience.
