Mayfield (shoulder) struck out four over two perfect innings in a start of Single-A Lake Elsinore last Wednesday.

Mayfield made his first appearance since May 13 after he had been shut down with left shoulder discomfort, though Lake Elsinore never placed him on its injured list. One of the top lower-level prospects in the San Diego system, Mayfield has accrued a 4.84 ERA, 1.18 WHIP and 31:9 K:BB across 22.1 innings over seven starts at Single-A this season.

Bailey was scratched from the lineup ahead of Tuesday's game against the Rockies due to neck spasms, Susan Slusser of the San Francisco Chronicle reports.

While Bailey takes a day off to recover, Andrew Knizner will start behind the plate and could continue to do so if Bailey needs to miss any additional games.

The Diamondbacks transferred Mena (shoulder) to the 60-day injured list Tuesday, Alex Weiner of ArizonaSports.com reports.

Mena landed on the injured list Saturday due to a teres major strain in his right shoulder. Now that he's on the 60-day IL, he won't be eligible to return to the D-backs' bullpen until early August. His spot on the 40-man roster will be given to Tayler Scott, who was selected from Triple-A Reno in a corresponding move.

The Diamondbacks placed Montes De Oca on the 15-day injured list Tuesday with right elbow inflammation.

Montes De Oca reported discomfort in his elbow after Monday's contest, and an MRI revealed inflammation Tuesday. He'll remain on the shelf for at least the next 15 days as a result, and with Jeff Brigham and Justin Martinez (elbow) also leaving the active roster, the D-backs will bring in Kevin Ginkel, Bryce Jarvis and Tayler Scott as bullpen reinforcements.

The Diamondbacks optioned Brigham to Triple-A Reno on Tuesday.

Brigham's demotion comes after he surrendered three runs without recording an out during Monday's win over Seattle. With Justin Martinez (elbow) and Christian Montes De Oca (elbow) moving to the IL, the D-backs will call up Kevin Ginkel, Bryce Jarvis and Tayler Scott to reinforce their bullpen.

The Diamondbacks selected Scott's contract from Triple-A Reno on Tuesday.

Scott will come up alongside Kevin Ginkel and Bryce Jarvis to replace Jeff Brigham, Justin Martinez (elbow) and Christian Montes De Oca (elbow) in Arizona's bullpen. Scott, 33, turned in a 5.40 ERA and 1.68 WHIP in 16.2 innings during his time with the Astros this year, though he's fired 3.1 shutout innings in Triple-A since joining the D-backs organization.

The Diamondbacks recalled Jarvis from Triple-A Reno on Tuesday.

Jarvis will be promoted as part of a flurry of roster moves that also includes Kevin Ginkel and Tayler Scott joining the active roster, while Justin Martinez (elbow) and Christian Montes De Oca (elbow) land on the IL and Jeff Brigham returns to Triple-A. Jarvis has given up six earned runs in 7.1 major-league innings this season and will likely be reserved for low-leverage work while in Arizona.

The Diamondbacks placed Martinez on the 15-day injured list Tuesday due to a sprained UCL in his right elbow.

The right-hander experienced tightness in the elbow during the ninth inning of Monday's contest, and a UCL sprain is an ominous initial diagnosis. The severity of the issue isn't yet known, and manager Torey Lovullo said Martinez is headed for a second opinion on the MRI result, per Nick Piecoro of The Arizona Republic. Even a low-grade sprain could require a lengthy absence, with Tommy John surgery likely being the worst-case scenario. Shelby Miller is likely to be the next man up as Arizona's closer.

The Diamondbacks recalled Ginkel from Triple-A Reno on Tuesday.

Ginkel will be joined on the trip from Reno by Bryce Jarvis and Tayler Scott, who will all join the big-league squad to replace the injured Justin Martinez (elbow) and Christian Montes De Oca (elbow), as well as the demoted Jeff Brigham. Ginkel hasn't found much success in the big leagues this year with a 12.60 ERA through 10 innings, though he has the potential to bounce back after posting a 3.21 ERA in 70 MLB frames last season.

Smith is out of the lineup for Tuesday's game in San Diego.

Smith is on the bench for the a third time in a seven-game span. The catcher played in three consecutive games between Saturday and Monday in which he went 3-for-13 with a home run. As Smith rests Tuesday, Dalton Rushing steps in behind the plate, batting ninth.
