Sent to Triple-A
The Diamondbacks optioned Walston to Triple-A Reno on Monday.
ANALYSIS
Walston was dispatched to minor-league camp along with right-handers Slade Cecconi and Corbin Martin after all three pitchers fell short in their bids for spots on Arizona's Opening Day roster. Unlike Cecconi and Martin, Walston has yet to make his MLB debut, but the Diamondbacks saw enough potential in him to protect him from the Rule 5 Draft this winter and add him to their 40-man roster. The 22-year-old southpaw will be returning to Reno, where he posted a 4.52 ERA and 1.57 WHIP over 149.1 innings while pitching mostly in hitter-friendly venues in the Pacific Coast League.

Past Fantasy Outlooks
2021
2020
The youngest player at Arizona's alternate training site, Walston proved up to the challenge, showing an improved changeup and improved command against older hitters. A 6-foot-5, 195-pound southpaw, there's still some projection possible with Walston, even though his velocity already ticked up from the low-90s to the mid-90s after signing for $2.45 million in 2019. His plus slider is arguably his best pitch, and it is important that his changeup and curveball continue to improve in the coming years. He won't turn 20 until late June, so it's too early to say anything definitive with regards to his floor or ceiling. That said, athletic, tall lefties with mid-90s fastball velocity and good command of a four-pitch mix are very rare. He should spend the year at Low-A and High-A, where going deep into starts and building up his workload will be a priority.
