July 11: RHP Slade Cecconi optioned to Triple-A; RHP Miguel Castro reinstated from 15-Day IL
The D-backs optioned Cecconi to Triple-A Reno on Thursday and activated Castro from the 15-Day injured list in a corresponding move. Cecconi is 2-6 with a 6.14 ERA and 53 strikeouts in 14 appearances (13 starts), and most recently allowed three earned runs and four hits in four innings against the Braves on Wednesday.

The 25-year-old allowed a combined 11 earned runs over his last three starts and had not earned a win since June 18.

“We felt like he lacked a little bit of consistency,” Lovullo said. “He showed some dominant stuff, but he couldn’t maintain it.”

Castro last pitched for the D-backs on April 20 against the Giants before he was subsequently placed on the 15-day IL on April 23 (retroactive to April 21) with right shoulder inflammation. He allowed just three hits in six innings across four rehab outings, split between the Arizona Complex League and Reno.

“He’s been grinding away at getting healthy,” Lovullo said. “He had electric stuff in his two rehab outings, and he’s ready for this opportunity again.”

Expected return: Late August/early September
Two games into a rehab assignment in the Rookie-level Arizona Complex League, Lawlar reinjured his left hamstring and is expected to miss six to eight weeks, D-backs manager Torey Lovullo said on July 10. The club's top prospect initially injured his left hamstring while legging out a triple in the ninth inning of Triple-A Reno's June 15 game. Lawlar had an MRI exam on June 17 that showed a Grade 1 strain.

The 2021 first-rounder also landed on the IL earlier this year after opening the 2024 campaign with a thumb injury. He played his first Minor League game of the season on May 29. (Last updated: July 10)

LHP Eduardo Rodriguez (left lat strain)
Expected return: Early August
Rodriguez, who was injured on March 19 in a Cactus League game, underwent another MRI on July 6, which showed that his lat has healed. So he will begin to ramp up his throwing program.

His initial throwing program was paused after he experienced some discomfort in the left lat following an April 9 bullpen session. On April 17, Rodriguez was moved to the 60-day IL. Rodriguez threw a bullpen session on July 9 and threw a simulated two-inning bullpen and 30 pitches on July 12. (Last updated: July 12)
