Riley Smith
26-Year-Old PitcherRP
2021 Fantasy Outlook
A starter at the upper levels of the minor leagues, Smith broke in with the Diamondbacks as a long reliever in 2020. He took the ball just six times but totaled 18.1 innings, pitching to a sparkling 1.47 ERA and 1.09 WHIP. The right-hander rode his sinker, averaging 93.3 mph, to a 47.8% groundball rate and in turn limited the opposition to a single home run (70 batters faced). Some estimators peg his deserved ERA roughly two runs higher than it was in his debut, and Smith does not currently any great swing-and-miss pitches, but the Diamondbacks have to be highly encouraged by what they saw from a player taken in the 24th round in 2016. It's not clear whether Smith will return to the farm and resume his development as a starter or remain in the big-league bullpen. The team would be smart not to mess with a good thing as Smith is already 26 years old. Read Past Outlooks
Provides bulk relief
PArizona Diamondbacks
June 14, 2021
Smith allowed two runs on four hits and struck out five over 4.2 relief innings in Sunday's 10-3 loss to the Angels.
ANALYSIS
Smith has been needed for similar bulk-relief appearances, as Arizona's rotation is decimated by injuries and poor performance. On Sunday, he spelled Jon Duplantier, who departed after 1.1 innings and six runs allowed. It's uncertain if Duplantier will remain in the rotation after a four-start run yielded a 13.15 ERA. Diamondbacks manager Torey Lovullo apologized to reporters for being late to the post-game press conference, per Nick Piecoro of the Arizona Republic, telling the scribes they were discussing plans for the rotation, which could mean the end of Duplantier. With so many injuries, there are few options available, but Smith could be one. Even though his track record as a starter in 2021 hasn't been good (1-3, 7.36 ERA, five starts), the right-hander has a 2.79 ERA and 1.29 WHIP over the last 19.1 innings as a reliever.
