Birthday boy Brack leads practice at Phoenix.

Kenny Brack celebrated his 37th birthday today by leading the field in opening practice for Sunday's Purex/Dial 200 at Phoenix International Raceway. The Honda-powered Team Rahal driver was fast from the opening bell, leading the morning practice and finishing second to fellow Honda-powered driver Dario Franchitti in the warmer, and slightly slower, afternoon session.

Franchitti's turn of speed in the afternoon practice was enough to place him third overall on the combined time sheet, just two-thousandths of a second ahead of his Andretti Green Racing teammate, Tony Kanaan.

As at the season-opening race in Homestead, Florida, last month, rising temperatures slowed everyone in the second practice, but Honda-powered drivers dominated, with Franchitti, Brack and team owner/driver Michael Andretti running 1-2-3 in the session for Honda.

Andretti ended the day sixth quickest, while series rookie Roger Yasukawa improved his time by five-tenths of a second to end the day 12th overall.

Practice continues Saturday morning, with single-car qualifying scheduled to begin at 2 p.m. ET on the 1-mile desert oval. The race starts at 3:30 p.m. ET Sunday and is scheduled to be televised live on ABC.

Kenny Brack (#15 Pioneer/Miller Lite Team Rahal Honda) Fastest in the morning practice and overall: "Phoenix is a tricky track. It has always been that way. It has two different ends on it. It requires quite a lot from the car. We have a good car for that kind of a 'one lapper' [qualifying] right now, I think. So we can continue to refine that package a little bit. If you are struggling today, then you have to guess on a qualifying setup tomorrow. Chances are, you can go wrong. At least we have a stable platform for tomorrow to try to improve. Being fastest helps a little bit that way."
