Hamilton has 13 steals in 14 attempts since being called up on Sept. 2, and he's stolen more bases than anyone else in the majors since his big league debut. He hit .368 in 13 games with the Reds after being called up from Triple-A Louisville in September.
Cole, the top pick in the 2011 MLB amateur draft, was arguably Pittsburgh's top starter down the stretch. The right-hander went 10-7 with a 3.22 ERA in 19 starts after being promoted to the majors in June. The 23-year-old is 4-0 with a 1.69 ERA since Sept. 1. He will only be used if starter Francisco Liriano struggles or is injured.
