The bullpen was actually stretched out in three of the past four games (Sunday, Tuesday, and Thursday), although we did have an off-day mixed in there as well - in those three games, the bullpen had to throw 16 2/3 innings.
With Wednesday's game mixed in there as well, that means the bullpen has thrown 18 2/3 innings in four games this week (allowing 5 runs - the two fluke runs by Izzy on Sunday, the two Thompson gave up on Tuesday, and the one Flores gave up on Wednesday).
So the point that Jimenez gives us a little breathing room in the bullpen this weekend is an excellent one.
What happens Tuesday obviously depends on how Carp's bullpen session goes tomorrow, and whether he wakes up Sunday pain-free. If so, he'll likely get the start Tuesday in Milwaukee.
If not - my guess is Thompson gets the start. It won't be Narveson, who's scheduled to pitch this weekend for Memphis (but watch the boxscores; if he gets skipped then that's a clue), but it could be Cate getting the callup.
