Jimenez will serve as the Athletics' opening pitcher for Tuesday's game against the Royals, Martin Gallegos of MLB.com reports.

He'll be making his first career start, but Jimenez is unlikely to cover more than two innings before turning the game over to Hogan Harris, who is expected to be called up from Triple-A Las Vegas to serve as the Athletics' bulk reliever. Jimenez recently returned from an extended stay on the injured list due to a strained shoulder and has tossed 1.1 innings, giving up two earned runs over his first two appearances since being reinstated.

Jarvis gave up one earned run on two hits and one walk over 3.2 innings out of the bullpen en route to picking up his first big-league win in Saturday's 8-1 victory over the Padres in the second game of a doubleheader.

Jarvis pitched behind opener Scott McGough, who tossed 2.1 scoreless innings before turning the game over to the rookie. Though Jarvis has now turned given up just two earned runs over 6.2 innings through his first two appearances with Arizona, he may end up serving as more of a pure reliever going forward rather than a primary pitcher. Arizona is expected to get some reinforcement to its rotation later this week, when Zach Davies (back) will likely be activated from the 15-day injured list.

Curtiss underwent surgery Tuesday to remove a loose body from his right elbow, Tim Britton of The Athletic reports.

Curtiss was diagnosed with the loose body last week and can now officially be ruled out for the remainder of the 2023 campaign. He made only 15 relief appearances this season at the MLB level and posted a 4.58 ERA and 16:8 K:BB across 19.2 innings.

Weaver was signed by the Mariners to a major-league contract and was added to the active roster Tuesday.

Weaver was released by the Reds after he allowed four runs in two of his last three starts. Following the All-Star break, his ERA rose as high as 7.22 and currently sits at 6.87. The signing comes the same day Emerson Hancock was moved to the 60-day injured list with a right shoulder strain. The Mariners had planned on operating with a six-man rotation prior to Hancock's injury, so Weaver could slot into that spot or work as a long man out of the bullpen.

The Giants optioned Hjelle to Triple-A Sacramento on Tuesday.

Hjelle surrendered six earned runs on 10 hits over 4.2 innings of long relief in Monday's series opener against the Phillies. He carries an 8.59 ERA across 22 total major-league innings this year.

San Francisco activated Walker from the paternity list Tuesday.

Walker will return to the Giants' bullpen mix Tuesday night in Philadelphia after welcoming a new addition to his growing family. The 27-year-old right-hander has posted a stellar 2.23 ERA and 50:13 K:BB across his first 44.1 major-league innings this season.

Antone (elbow) agreed Sunday to extend his rehab assignment an additional 10 days, Charlie Goldsmith of The Cincinnati Enquirer reports.

After opening his rehab assignment July 25, Antone was nearing the end of his 30-day rehab window, but MLB rules will allow him to extend the assignment because he's working his way back from August 2021 Tommy John surgery. Antone was initially expected to be fully cleared for spring training, but those plans were thwarted when he suffered a right flexor strain while rehabbing over the winter. He appears to have steered clear of any further setbacks since he started throwing again in April, and he's turned in respectable results thus far during his rehab assignment. In seven appearances at Triple-A Louisville, Antone has given up four earned runs on nine hits and two walks while striking out seven over 7.1 innings.

The Cardinals selected Barnes' contract from Triple-A Memphis on Tuesday.

Barnes has spent all of this season at the Triple-A level, collecting a 2.47 ERA and 45:22 K:BB over 51 innings at three different stops. The 33-year-old reliever will provide a fresh arm to a Cards' bullpen that's been overworked.

Marte (elbow) was activated from the 60-day injured list and optioned to Triple-A Salt Lake on Tuesday.

Marte struck out 10 batters and allowed two hits and two walks over 5.2 scoreless innings across five appearances for Salt Lake since moving his rehab assignment from the rookie-level Arizona Complex League on Aug. 8. He hasn't pitched in the majors this season while recovering from a right elbow stress reaction, and the Angels have opted to give him a little more time at Salt Lake. Marte owns a 7.80 ERA over 15 career appearances in the majors and would likely have to settle for a lower-leverage role out of the bullpen when he's given a chance with the big club.

Treinen (shoulder) began a rehab assignment Tuesday in the Arizona Complex League, Eric Stephen of SBNation.com reports.

Treinen has been sidelined all year following offseason shoulder surgery, but he's on the right track now with a return to live appearances in the ACL. In his rehab debut Tuesday, he retired the side in order on two strikeouts and a flyout. The veteran reliever could become an option for the Dodgers' bullpen sometime around early-to-mid September if he continues to prove his health and effectiveness on the farm.
