I love the news nets

Yahoo, my morning headline source, had 5 articles in the cycling section this morning. They were titled;

• Discovery set record straight to put Armstrong in yellow
  Armstrong Claims Lead
  Armstrong takes Tour lead as Zabriskie crashes
  Armstrong in yellow as Zabriskie hits the tarmac
  Armstrong in yellow as Discovery Channel wins team time-trial

I saw the cycling last night, so I knew what the rticles were about just from the headlines. Can you work it out?
