Lawrence was a waiver claim in late June and allowed three runs with a 6:7 K:BB over 6.1 innings with the Nationals. The righty holds a 7.34 ERA, 1.95 WHIP and 43:28 K:BB across 34.1 frames between the Nats, Twins and Pirates this season, and this is the third time since late May that he's been designated for assignment.

Clayton Beeter kept Baltimore off the board with a scoreless ninth frame, and then Lawrence got the call for the 10th after Washington took the lead in the top of the inning. Lawrence, who was making his Nationals debut Saturday, has previous closing experience with the Rockies, though it's hard to envision him being trusted with consistent high-leverage work. Lawrence has a 7.76 ERA, 1.90 WHIP and 37:22 K:BB over 29 innings between the Pirates, Twins and the Nats this year.
