Developing curveball Smith worked on his curveball during the offseason, Steve Gilbert of MLB.com reports. Impact Because Smith feels his slider is too similar in speed to his fastball, the left-hander wants a slower breaking ball. It was a pitch he introduced last season, but a bout with COVID-19 last summer limited him to just 14 innings. He never got a chance to develop it fully, although he did throw it 20 times and did not give up a hit on it, per Statcast. "The curveball is coming along really well," Smith said. "I picked it up pretty quick, actually. I think it's right where I need it to be. I think it's going to help my repertoire a lot this season." Smith is expected to be part of the Diamondbacks' rotation in 2021.
