The Arizona Diamondbacks on Monday recalled right-handed reliever Edwin Uceta from Triple-A Reno and placed left-handed pitcher Kyle Nelson on the 15-day injured list (lower-back spasms) retroactive to Aug. 5.

Uceta, 24, has played in six games for the D-backs spread out from April to late July in his last MLB appearance.

He has a 4.26 ERA and has allowed eight hits and six earned runs to go along with six walks and seven strikeouts over 12.2 innings with Arizona.

In 20 Triple-A games with three starts this season, Uceta has posted a 3.67 ERA and 1.14 WHIP over 34.1 innings. Opposing batters have also averaged .185 against the righty.

Uceta was acquired by the Diamondbacks in October 2021 off waivers.

The 14 appearances for the Los Angeles Dodgers last season make up his only other MLB experience before this season.

Nelson, 26, has appeared in 38 games (one start) for the Diamondbacks this year. In 34.1 innings pitched, the lefty is 1-0 with a 1.57 ERA, 0.90 WHIP and 27 strikeouts.

In his last seven appearances for Arizona, he has only allowed two hits and no walks while striking out seven in 7.1 innings pitched. Nelson’s ERA was 0.00 and his WHIP was 0.27 in that span.

The D-backs host the Pirates in the first of a four-game set on Monday at 6:40 p.m. on 98.7 FM Arizona’s Sports Station.

Arizona RHP Zac Gallen (6-2 3.31 ERA) is scheduled to start against Pittsburgh RHP Tyler Beede (1-1, 3.89).
