Yeah hopefully the FO is looking at an arm like Plesac or maybe a veteran arm from a rebuilding team like the Nats, or A's, just to eat up some innings in the short term if need be.
Everything is timing agreed. It's bad timing that all those arms are injured all at once. Can't do much. With Manoah being awful, Jays definitely could have used some of that depth.
Gausman, Bassitt and Berrios all have been rock solid this season. You should be able to replace a Kikuchi if need be or improve on what Manoah has done. Though replacing one of those three arms would be tough. I know it's a "What If" though with the lack of depth options available, hopefully this FO looks at ways to resolve the issue. Ryu definitely can be one piece of the puzzle when he's ready, though perhaps this team could also look at adding another No. 2/3 starter closer to the trade deadline so this isn't a concern down the stretch or in the Postseason.
