The Chicago Bulls' vaunted defense locked down the low horsepower Milwaukee Bucks in the third quarter of Friday night's match up, holding the Bucks to only 18 points as they extended their lead to 79-68 after three. Reigning MVP Derrick Rose had a scintillating quarter, brining his point total to 30 on the night, thanks mostly to frequent trips to the free throw line. Bucks point guard Brandon Jennings, who had outpaced Rose in the first half, went cold in the third quarter, bricking a number of long range shots. The Bucks will have a long road ahead of them in the fourth, as the Chicago defense continues to tighten its grip as the Bucks' shooting percentage slips below 40% on the night.
