Well...their 2nd starter is the "To Be Announced" spot from Olsen's absense and if they make no changes to order, it looks like it COULD be Livan. There's a lot of time for adjustments between now and June 4 though. Injuries, missed starts, extra rest days (Livan would be the one who needs that if anyone).
It's already going to be thrown out of whack with Olsen going on the DL. Livan took his turn early last time with 3 days rest.
If he just takes over the vacant #2 spot, you might not see him. As of today, they only have the probables listed through June 3, so check the link closer to the game, although it is subject to change, especially with a team-changer like Strasburg involved.
Olsen is expected to miss two starts (both listed as "TBA"). I wouldn't expect Strasburg to take over Olsen's #2 spot though.
MASN is reporting June 4 though.
