Jack Sprague proved to be fastest on day one of the NASCAR Craftsman Truck Series test at Martinsville Speedway Tuesday in preparation for the Kroger 200 to be held at the legendary Virginia track on March 29.

Sprague's No. 2 Kevin Harvick, Inc Chevrolet Silverado posted the best lap of the day touring the .526-mile Martinsville oval in 20.062 seconds (94.387 miles per hour) in the afternoon test session. The speed was just good enough to top Erik Darnell's lap of 20.068, also set in the afternoon session, and the top time 20.075 seconds in the morning practice posted by rookie Brian Scott in the No. 16 Shark Energy Drink/Albertsons Chevy.

Scott's top lap of sunny and cool morning session was just one of many surprises in the marathon seven-hour test. While Sprague and Darnell were also fast in the morning session placing fourth and fifth, respectively, Darnell's Roush-Fenway teammate Colin Braun was also quick driving his Ford F150 to the third-best time in session ripping off a lap of 20.088.

Meanwhile, Ted Musgrave led a flock of veterans to the top of the leader board in session number one. Driving for the hometown Martinsville favorite HT Motorsports team, Musgrave steered his No. 59 Team ASE Toyota Tundra to second in the morning session with a lap of 20.83. Other veterans in the Top-10 contingent in the morning session included Mike Skinner (sixth, 20.131), current division point's leader Kyle Busch (seventh, 20.143), former Martinsville winner Rick Crawford (eighth, 20.147), defending Truck Series champion Ron Hornaday, Jr. (ninth, 20.216), and Travis Kvapil (10th, 20.222).

While Sprague and Darnell marched to the top of the timing charts in the four-hour afternoon practice session, it too held its share of surprises.

Rookie Donnie Lia, a winner at Martinsville in the NASCAR Whelan Modified Series a year ago, posted the third-best time of the afternoon driving the No. 71 TRG Chevy Silverado to a lap of 20.087 seconds.

Jon Wood, another former Truck Series winner at Martinsville, showed he still had the magic coming home fourth in the afternoon session with a time of 20.108. Former Martinsville Late Model star Timothy Peters was fifth quick at 10.113 while Musgrave (20.121), Skinner (20.122), Crawford (20.159), Scott Speed (20.170) and Terry Cook (20.185) completed the Top-10 in the final afternoon practice tally.

The test also featured a pair of new faces as Chrissy Wallace, daughter of NASCAR Nationwide racer Mike Wallace, and Adam Crawford, son of Rick Crawford, took their first official laps in a NASCAR Craftsman Truck Series racer.

Wallace, driving the No. 03 Germain Racing Toyota Tundra, looked completely at home on the tight Martinsville oval posting a 20.451-second lap as her best effort of the day. Crawford, meanwhile, crawled into a second Circle Bar Racing Ford late in the afternoon session turning in a best lap of 20.549.

Other notables participating in the test included former NASCAR Sprint Cup team owner/crew chief and current television broadcaster Andy Petree, who drove a second HT Motorsports Toyota to 17th on the speed charts with a very respectable lap of 20.278 in the afternoon session.

The two practices were run virtually incident free with only Andy Lally and Brian Silas experiencing any trouble. Lally was the first to take the track in his No. 7 TRG Chevy in the morning session, but his time atop the leader board was short when his mount experienced engine problems forcing the team to switch powerplants and miss most of the remaining morning practice.

Silas, meanwhile, was the only driver to get turned around on the tight Martinsville oval spinning as he exited Turn 4 one hour into the afternoon practice. Fortunately, Silas' No. 48 Chevy stayed off the wall and he was able to finish out the day without any further problems.

A second day of practice for the Kroger 250 at Martinsville Speedway will be held Thursday, March 13, from 9 a.m.-5 p.m. Eastern Time. The session is open to the public free of charge.
