Walls (groin) will see a specialist Wednesday, MLB.com reports.

Walls has been sidelined since Aug. 12 and had recently begun running and strength exercises. However, he felt discomfort and will now seek additional medical evaluation. The results should provide clarity on whether Walls can return this season, though he doesn't appear to be close to activation.

Mazur (0-2) took the loss Tuesday against the Nationals, allowing five runs (four earned) on 10 hits and no walks while striking out five in six innings.

Mazur set a career-worst mark with 10 hits allowed, and five of the 10 hits went for extra bases. The biggest hit of the night against him was a two-run blast in the fourth by James Wood. Mazur was able to finish strong with two scoreless frames and tied his career high with six innings. He's tentatively lined up to complete a two-start week with a tough matchup against the Phillies.

Aranda (wrist) has resumed swinging a bat, but his wrist is still not fully healed, MLB.com reports.

Aranda has been out for a month due to a fractured wrist, and the symptoms have recently improved. He's set to see a doctor Sept. 10, which should clarify whether he has a chance to return this season. If Aranda does get back in the lineup, it will likely only be for the final few games.

Winn (hand) retired all three batters faced while pitching for Triple-A Round Rock on Tuesday, Evan Grant of the Dallas Morning News reports.

Winn looked sharp in what was his first game action since landing on the 15-day injured list Aug. 20 with nerve irritation in his thumb -- an issue that was eventually classified as "arm fatigue." The right-hander needed 17 pitches (11 strikes) to set down the three opposing batters. Winn could rejoin the bullpen as early as this weekend when the Rangers open a three-game series against the Astros on Friday.

Simpson went 1-for-4 with a run scored and a stolen base Tuesday against the Mariners.

Simpson was the catalyst for the Rays' offense in the seventh inning, when he reached base on an infield single, stole third base and then came around to score the eventual game-winning run. This marked his first stolen base in seven starts, but he now has 39 total bags on the season in only 89 games. Simpson has also led off 17 straight contests for the Rays, scoring 11 runs and driving in six in that span.

Mahle (shoulder) allowed five runs on five hits and one walk while striking out one over one-plus innings for Triple-A Round Rock on Tuesday.

Mahle reached his pitch count before getting anyone out in the second inning after throwing 36 pitches (23 strikes) in an outing that was planned to go two full innings. He retired the first two batters faced before allowing three consecutive hits and two runs in the first inning. The right-hander came back out for the second inning and gave up a three-run home run. The Rangers had hoped Mahle could rejoin the pitching staff after one rehab outing, per Evan Grant of the Dallas Morning News, who noted Mahle's velocity across all pitches was down about one mph for the night compared to his season averages. The team's decision-makers may want to reconsider the pitcher's next step.

Diaz went 1-for-2 with two walks and two runs scored Tuesday against the Mariners.

Diaz reached base on a walk in both the first and seventh innings while coming around to score on each occasion. He's reached base multiple times in 15 of his last 25 starts dating back to Aug. 1. In that span, he's hit .302 with four home runs, 14 RBI and 14 runs scored while maintaining an .856 OPS.

Barrosa started in left field and went 1-for-3 with a run scored in Tuesday's 5-3 win over the Rangers.

In the Diamondbacks' first game without primary left fielder Lourdes Gurriel (knee), the switch-hitting Barrosa drew the start against a left-hander (Jacob Latz). Going forward, left field could consist of Jake McCarthy against right-handers while Barrosa or Blaze Alexander take over against southpaws.

Alexander started in center field and went 2-for-4 with an RBI and was caught stealing in Tuesday's 5-3 win over Texas.

Alexander started a second straight game in center field, both coming against left-handers. With the news that Lourdes Gurriel is done for the season with a torn ACL, there's a greater need for Alexander's right-handed bat in the outfield. He has experience in center field and replaced Gurriel in left field Monday.

Lawlar went 2-for-3 with a double and a run scored in Tuesday's 5-3 win over the Rangers.

A great weight was removed from Lawlar's shoulders when he doubled in the fifth inning. That hit snapped an 0-for-31 streak in the majors this season and 0-for-36 going back to his first cup of big-league coffee in 2023. He followed up with a sharp single in the seventh inning, attacking a 1-1 sinker over the plate. Lawlar did not see a two-strike count, which is something manager Torey Lovullo talked about after the game with Alex Weiner of Arizona Sports. " I know he's trying to do everything right and perfect, take pitches, see pitches, drive up pitch counts and different things," Lovullo said. "I went to him before the day started. I said, 'Go early if you need to go early, get your swing synced up.'" With the hitless burden out of the way, Lawlar may be more relaxed and confident going forward.
