MLB Player News

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.

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.

Jansen worked around a walk in a hitless and scoreless ninth inning in Tuesday's 5-1 win over the Royals. He struck out two.

The veteran closer got loose for what was going to be a save chance before the Angels tacked on an additional run with two outs in the top of the ninth. Interim manager Ray Montgomery still turned to Jansen despite it becoming a non-save situation, and Jansen needed 22 pitches to shut the door. Jansen has now worked three of the last four days and will presumably be unavailable for Wednesday's contest.

Rivera went 2-for-5 with four RBI in Tuesday's 6-2 win over the Padres.

Rivera took care of business with a pair of two-run singles to account for a majority of the Orioles' runs in this win. He has gone 6-for-17 (.353) over five games since his most recent call-up Aug. 27. He's sharing third base with Jeremiah Jackson for now, though both players figure to see their chances drop once Jordan Westburg (ankle) is able to return. Over 94 plate appearances in the majors this year, Rivera is slashing .253/.309/.287 with no home runs, three doubles, nine RBI, three runs scored and one stolen base.

Cowser went 2-for-4 with a stolen base and a run scored in Tuesday's 6-2 win over the Padres.

Cowser's bat has cooled off a bit recently -- this was his first multi-hit effort in eight games. Over that span, he's 4-for-30 (.133) with a 1:15 BB:K. The outfielder is up to a .215/.278/.398 slash line with 12 home runs, 30 RBI, 28 runs scored and nine steals across 283 plate appearances this season.

Jackson went 1-for-4 with a solo home run, a second RBI and a walk in Tuesday's 6-2 win over the Padres.

Jackson opened the scoring with a solo shot in the first inning. This was his fourth homer of the season, three of which have come over the last four games. He's now at a .333/.358/.539 slash line with 17 RBI, 15 runs scored, five doubles, two triples and no stolen bases over 28 contests to begin his big-league career. Jackson's hot hitting has earned him a near-everyday role in the Orioles' lineup, and if he can keep it up, he'll be well-positioned to contribute next season as well.
