EDGE Analysis
Lawrence was called up by the Blue Jays on Thursday, but he didn't make any big-league appearances over the last few days. The right-hander will head back to the minors after Julian Merryweather (oblique) was reinstated from the 60-day injured list ahead of the second game of Monday's doubleheader against the Orioles.
