Diamondbacks' Blake Walston: Back down to Triple-A
Rotowire
Walston was optioned to Triple-A Reno on Thursday.
It was a brief stint for Walston, who was recalled by the Diamondbacks on Wednesday. He threw for 3.2 innings in Wednesday's loss to the Dodgers, allowing two runs on three hits and four walks while striking out five. The move corresponds with Arizona acquiring right-hander Matt Bowman from the Twins on Thursday, while Merrill Kelly (shoulder) was transferred to the 60-day IL.

Diamondbacks' Blake Walston: Needed for length in loss
Rotowire
Walston allowed two runs on three hits and four walks while striking out five over 3.2 innings in Wednesday's 8-0 loss to the Dodgers.
Walston, a starter at Triple-A Reno who made his major-league debut Wednesday, was recalled earlier in the day following Tuesday's surprise bullpen effort that left the club in need of a fresh arm. His length was needed immediately, as starter Jordan Montgomery was ambushed by the Dodgers early. Walston navigated around a walk and two hits over three scoreless frames before running into trouble in the seventh inning. That's when the left-hander's shaky command -- three walks including one with the bases loaded -- caught up to him.

Diamondbacks' Blake Walston: Recalled to majors
Rotowire
Walston was recalled from Triple-A Reno on Wednesday.
Walston didn't make the cut for Arizona's Opening Day roster, but he will get a chance to play with the team after five years in the minors. The lefty pitcher has logged a 4.79 ERA and 1.88 WHIP over 20.2 innings in five games played with the Reno Aces so far this year. The 22-year-old will be making his major-league debut when he gets into a game and could work in long relief since he's pitched out of Reno's rotation.

Diamondbacks' Blake Walston: Sent to Triple-A
Rotowire
The Diamondbacks optioned Walston to Triple-A Reno on Monday.
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.

Diamondbacks' Blake Walston: Protected from Rule 5 Draft
Rotowire
The Diamondbacks added Walston to their 40-man roster Tuesday.
Walston spent all of 2023 with Triple-A Reno, posting a 4.52 ERA and 1.57 WHIP in 149.1 innings. Teams won't be able to pluck Walston away from Arizona in the upcoming Rule 5 Draft, but given his command issues and low strikeout totals, the 22-year-old southpaw has work to do before he can be considered for the major-league roster.

Diamondbacks' Blake Walston: Getting crushed in Double-A
Rotowire
Walston has a 7.12 ERA, 1.93 WHIP and 35:17 K:BB through 36.2 innings (eight starts) for Double-A Amarillo.
After Walston dominated in High-A to open the year, there was reason to expect more than this following his promotion in early May. The southpaw has given up 53 hits, including seven home runs, across those 36.2 frames since his promotion. That said, he's still a few days shy of his 21st birthday, and Walston struggled some after being promoted to High-A last year before coming back stronger in 2022, so he may just need some adjustment time.

Diamondbacks' Blake Walston: Gets taxi squad nod
Rotowire
Walston will be on Arizona's taxi squad, Nick Piecoro of The Arizona Republic reports.
Walston is one of the best pitching prospects in the Diamondbacks' system, but he doesn't turn 19 until later this month and has not yet pitched above short-season ball. He had a 2.45 ERA, 0.91 WHIP and 17:2 K:BB in 11 innings last year after Arizona selected him with the No. 26 overall pick in the draft.
