Braves starting pitcher Shelby Miller had an up-and-down season with the Cardinals in 2014. He began the season by going 6-2 with a 2.79 ERA before going 2-7 with a 5.11 ERA over his next 16 appearances (15 starts).

Miller, however, was able to finish the season on a high note, going 2-0 with a 2.08 ERA and .190 opponents' batting average over his final seven starts. Miller attributes his success down the stretch to incorporating a sinker into his repertoire, per FOX Sports South.

"I said I'm going to throw some of these, and we'll see where it's at," Miller said of a conversation he had with catcher A.J. Pierzynski before an Aug. 23 start against the Phillies. "It felt good so we just went with it. I started throwing it literally within three days. It's a good pitch that I picked up quick.

"I still need a lot of work with it. I need a lot of work with all my pitches. There's all sorts of ways to get better. But I think that's definitely a pitch that will help me be more efficient and take me deeper into games. That's [the sinker] going to be a huge pitch for me this year that's ultimately going to take me to the next level. Not only that but kind of mixing it all together, becoming more of a complete pitcher more than a thrower."

Miller added he will also begin to work more on his changeup, which he threw just 2.2 percent of the time in 2014, per FanGraphs.com.

"I know [Braves pitching coach] Roger [McDowell] has been known for changeups," Miller said. "A lot of great pitchers have come through this organization, [and] that's a pitch I would love to pick up. I want to be able to throw it more consistently, [and] have a little bit more confidence in it."
