Victor Zambrano 2 starts this week? Met Homies

[housefcards]

I'm using Victor Zambrano for 2 starts this week,but he is starting on WED. so how is it possible that he's getting 2 starts this week?
ESPN has him pinned for 2 starts and so does Rotoworld.
Do the Mets have a 4 man rotation? a double header this week? What am I missing. I see him as a good 2 start guy,if he gets 2 starts.both would be against poor offenses,Houston and LAA.
Pedro starts Tues,so he gets 2 starts.I need to know why these other 2 sites have him down for a 2 start week,which I hope.He pitched great his last outing. A little help please.
Thanks

AFAIK VZam pitches TUE not WED. I haven't heard anything about Willie shaking the rotation to get a Pedro/Oz match-up.

It is probably too late now but it has been changed. Pedro against Oz and then VZam on WED so I'm not sure that he'll get two starts.
