The prosecution in the Roger Clemens perjury trial is having a much better day Thursday than it had on Wednesday. Federal investigator Jeff Novitzky took the stand before a one-hour lunch break and broke down the evidence that could land Clemens on the business end of a perjury conviction.

The New York Daily News, along with various other media outlets, live-tweeted Thursday's proceedings and called the questioning of Novitzky by Clemens' attorney Rusty Hardin a "very interesting showdown."

On Wednesday, a beer can containing medical waste that supposedly links to Clemens to human growth hormone use was presented as evidence and on Thursday, Novitzky discussed that Miller Lite can. He testified to taking the bottom off the can to access the contents.

Here are some of the tweets from the Daily News (Durham is the prosecutor):

The beer can had cotton balls. Durham: "Are there what appear to be some kind of stains on that cotton ball." #Clemens

Novitzky says he put materials in clear plastic bag "so that we had a good chain of evidence." Jury sees photos of evidence bag. #Clemens

Novitzky describes handing the medical evidence over to the FBI after Congress referred Clemens testimony to the #DOJ.

Novitzky: "On the right there what you see are two vials, and one ampoule with the top broken off." Describes them as HGH, Primobolan, etc.

Novitzky says all of these items were turned over to the FBI on June 23, 2009, "per their request."

This trial was moving slowly until Wednesday when Andy Pettitte testified that there was a "50-50 chance" that he misunderstood Clemens 12 years ago when Clemens allegedly discussed his use of HGH. However, the day ended with the jury seeing drugs and needles presented as evidence, along with the testimony of Novitzky.
