Regan Smith on standby for Denny Hamlin at Watkins Glen

“Super sub” Regan Smith may be called into duty again this weekend. The veteran driver is on standby for Joe Gibbs Racing driver Denny Hamlin, who is on baby watch.

With longtime girlfriend Jordan Fish nearing her due date, Hamlin has insurance in a couple of ways. The first is that, if Fish goes into labor, Smith will drive Hamlin’s No. 11 Toyota, so no worries there. The second is due to Hamlin’s win at New Hampshire earlier this summer, he’s firmly locked into the playoff field.

Smith drove the No. 43 Richard Petty Motorsports Ford in place of the injured Aric Almirola at Charlotte and Dover earlier this year. He previously has subbed for Dale Earnhardt Jr., Tony Stewart, Kurt Busch and Kyle Larson.

Hamlin won the race at Watkins Glen last year. He is sixth in the driver standings with one win, seven top fives and 11 top-10 finishes.
