[H] Help with widow mines!

Hey fellow daynineians,

I am a gold level player who somehow got into platinum with the switch to HotS.  In general I am having a hard time dealing with widow mines, in this particular PvT I went early stargate for oracle harrass. This T came at me with only widow mines and I was powerless to stop him. Any ideas?
