In 1993, Sprague signed to drive the #74 BACE Motorsports car. Despite four top-ten finishes, he was released with just a handful of races left in the year. He finished nineteenth in points. Sprague returned to the Winston Racing Series ranks in 1994, winning 21 of 22 races he entered.
The following season, Sprague won at Phoenix, Nazareth, and Nashville Speedway USA, and won the championship. In addition, he returned to the Cup series, subbing for Ricky Craven at Bristol Motor Speedway, but finished 40th after a wreck. Despite winning the Truck Series championship, Quaker State did not return as Sprague's primary sponsor, forcing him to start the 1998 unsponsored. After a one-race deal with Big Daddy's BBQ Sauce at Portland Speedway, Sprague won The No Fear Challenge in his debut for sponsor GMAC, allowing them to join full-time as sponsor. He won five races total that season and finished second in points. He returned to the Busch Series to drive the #40 Channellock Chevy for Doug Taylor at Watkins Glen International, finishing sixth.
In 1999, Sprague won three races as well as the Craftsman Truck Series championship by eight points. He also drove at Watkins Glen in a Terry Labonte-owned car, finishing twelfth, and attempted the Exide NASCAR Select Batteries 400 for Tyler Jet Motorsports, but failed to qualify. He won three more times in 2000, but crashes caused him to drop to fifth in the standings. In 2001, NetZero became his primary sponsor, and he won seven poles and four races, and took home his third championship trophy.
Sprague took over the 16 Xpress truck full-time in 2004, winning six poles and the UAW/GM Ohio 250. He finished seventh in points. The following season, he won at Texas Motor Speedway, but late in the season, was released in favor of Mike Bliss and took over at newly formed Wyler Racing for Chad Chaffin. Despite switching teams mid-season, he finished eighth in points.
Sprague finished the 2006 season fifth in points with two wins and two poles. He returned to the Con-Way Freight Tundra for the 2007 season. Sprague started the 2007 season in the Craftsman Truck Series with a win in the Chevy Silverado HD 250 at the Daytona International Speedway. However, Sprague began to struggle throughout the year, even dropping out of the top 10 in points. This, combined with Con-way's departure at the end of the season, led Sprague to leave Wyler for Kevin Harvick Incorporated where he drove the #2 American Commercial Lines Chevrolet. Late in the year, he left KHI to return to Wyler Racing.
