John Gaub (back) is expected to throw and bunt on Thursday.
Gaub has been limited in the early days of camp due to back spasms. The 26-year-old left-hander made four appearances with the Cubs last season as a September call-up after posting a 3.42 ERA and 75/40 K/BB ratio over 55 1/3 innings. He'll be in the mix for a bullpen spot during spring training.
