Marte (knee) will be placed on the 10-day injured list ahead of Friday's series opener against the Reds, Nick Piecoro of The Arizona Republic reports.

Diamondbacks general manager Mike Hazen, manager Torey Lovullo and Marte's agent all met earlier Thursday, but Hazen declined to provide specifics on Marte's knee issue, only saying he expects Marte to rejoin the team following a stint on the injured list. How long that stint will be is the big question after Marte didn't show up for Arizona's series in Boston this week. Ildemaro Vargas figures to continue to see increased playing time in the middle infield while Marte is sidelined.

Witt went 2-for-4 with a solo home run, a walk and two additional runs scored in Thursday's 6-2 win over the Athletics.

Witt opened the scoring with a 402-foot blast in the first inning before crossing home again in the third and fourth frames. The superstar has been fantastic in August, posting a .972 OPS with seven extra-base hits, nine RBI, 20 runs scored and three stolen bases over 16 games this month. On the year, he's slashing .286/.362/.463 with 16 homers, 48 RBI, 71 runs scored and 33 steals across 486 plate appearances.

Jump (5-8) took the loss against the Royals on Thursday, allowing five runs on eight hits and three walks with three strikeouts over four innings.

Jump allowed runs in three separate frames, throwing 55 of 86 pitches for strikes with only five whiffs. After a double-digit strikeout performance Aug. 8, the 23-year-old has posted an ugly 4:7 K:BB over his past two outings and now owns a 6.75 ERA in seven starts since the All-Star break. He'll carry a 4.83 ERA, 1.51 WHIP and 88:40 K:BB across 82 innings this season into a home matchup with the Twins next week.

Dobnak did not factor into the decision in Thursday's 6-2 win over the Athletics, allowing six hits and four walks while striking out four over four scoreless innings.

Dobnak kept the Athletics off the board despite needing 96 pitches to complete just four innings. The 31-year-old has allowed two earned runs or fewer in eight of his nine outings this season, though he's completed more than five frames just three times. He'll take a 1.58 ERA, 1.40 WHIP and 29:20 K:BB across 45.2 innings with the Royals into a road matchup with the Blue Jays next week.

Megill earned the save in Thursday's 7-4 win over the Mariners, striking out one in a perfect ninth inning.

Megill was called on to face the heart of the Mariners' order in the ninth inning and retired the side on 13 pitches. It continued a strong second half for the 32-year-old, who's allowed only one earned run while locking down nine saves through 13 appearances since the All-Star break. For the season, he's 23-for-25 in save chances to go along with a 2.39 ERA, 0.82 WHIP and 55:12 K:BB across 49 innings.

Mitchell went 3-for-4 with a home run, two doubles, three RBI and two runs scored in Thursday's 7-4 win over the Mariners.

Mitchell tallied three extra-base hits after missing one game with a sore foot, highlighted by a solo shot in the eighth inning. The 27-year-old has now gone 7-for-10 over his past two games, though he's still sporting a lowly .654 OPS through 17 August contests. On the year, he's slashing .261/.356/.421 with nine homers, 54 RBI, 54 runs scored and 12 steals across 425 plate appearances.

Gasser did not factor into the decision in Thursday's 7-4 win over the Mariners, allowing four runs on four hits and four walks with four strikeouts over 3.2 innings.

Gasser was given a 6-0 lead in the first inning but was inefficient, throwing 46 of 77 pitches for strikes while matching a season-high four walks. It marked the second time the southpaw was unable to complete at least four frames in 15 starts this season and ended a streak of five straight outings where he allowed three earned runs or fewer. He'll take a 4.79 ERA, 1.29 WHIP and 72:23 K:BB across 77 innings into a road matchup with the Mets next week.

Kirby (8-10) took the loss against the Brewers on Thursday, allowing six runs on nine hits and two walks with three strikeouts over 3.1 innings.

Kirby surrendered all six runs in a nightmare first inning, when he allowed 12 hard-hit balls overall while generating just six whiffs on 84 pitches. It continued an inconsistent year for the 28-year-old, who has now allowed 11 earned runs over his past two starts after yielding just one earned run through his first two August outings. He owns a 4.18 ERA, 1.36 WHIP and 117:33 K:BB across 140 innings this season and will aim to rebound in a home matchup with the Phillies next week.

Hess (undisclosed) was transferred to the 60-day injured list at Double-A Somerset on Thursday, Conor Foley of YES Network reports.

Hess will miss the remainder of the season, finishing his 2026 campaign with a 4.45 ERA, 1.45 WHIP and 65:30 K:BB across 56.2 innings spanning 16 starts. The 23-year-old was believed to have a chance to make his MLB debut this season, but injuries got in the way. Hess was the 26th overall pick in the 2024 Draft.

In seven games since getting promoted to Triple-A Toledo, Briceno has gone just 4-for-24 with no home runs and nine strikeouts.

Briceno earned the promotion by slashing .297/.382/.672 with eight home runs across 76 plate appearances for Double-A Erie earlier in the season. So far, Triple-A hasn't been as welcoming for the 21-year-old, but he's shown good offensive upside throughout his time in the minors and should settle in with the Mud Hens eventually. Briceno remains the Tigers' top catching prospect and could start knocking on the door of the majors next year, though Dillon Dingler has solidified himself as Detroit's answer behind the plate, so Briceno may have to shift to a different position when he makes his MLB debut.
