I didn't have an issue using Merryweather there either. The Orioles suck and the Jays couldn't wait for a low leverage situation for much longer without risking the health of their only 4 reliable RPs. Only criticism would have been not taking Merryweather out when Santander was up (Saucedo sucks but Santander can't lefties), but using him in general was fine with me. As mentioned, the Jays need one or both of Pearson + Julian to be a late inning option if they want any chance at making the WC game or advancing past it.
