Cincinnati Reds shortstop prospect Edwin Arroyo (shoulder), the team's No. 3 prospect per MLB Pipeline, had season-ending shoulder surgery on Wednesday to fix a torn labrum in his left shoulder. The 20-year-old injured the shoulder diving back to first base last week in a Cactus League game and will now miss all of 2024. It's a tough break for one of the team's top prospects after he went 6-for-17 with three RBI in spring training action. When he returns in 2025, Arroyo will most likely be ticketed for Double-A Chattanooga. The 6-foot switch-hitter hits balls hard to all fields and should develop more power as he matures, but his development is going to be put on hold this year. The Puerto Rican product hit .252/.324/.433 with 13 homers, 60 RBI and 29 steals in 123 games last year with High-A Dayton and Chattanooga.

The Cincinnati Reds acquired infielder Santiago Espinal from the Toronto Blue Jays on Wednesday in exchange for right-hander Chris McElvain. The move comes on the same day that the Reds announced second baseman Matt McLain (shoulder) will open the season on the injured list and could need surgery. Noelvi Marte is also suspended for half the season due to performance-enhancing drugs, so Espinal will give the Reds some more infield insurance in 2024. Jonathan India now figures to start at the keystone with McLain on the sidelines, and the 29-year-old Espinal will back up India. Espinal hasn't been much of a fantasy asset in his four big-league seasons with the Blue Jays, slashing .273/.331/.367 with 11 homers, 99 RBI and 15 stolen bases in 346 games played.

Chicago White Sox right-hander John Brebbia (calf) went through fielding drills in camp on Wednesday after pitching an inning in a minor-league game on Tuesday. Brebbia strained his right calf during fielding drills in spring training in late February and is still working his way back from it. The 33-year-old is up in the air to be ready for Opening Day on March 28 next Thursday, putting strain an already extremely thin White Sox's bullpen. When healthy, the 33-year-old figures to be in the mix for saves chances in Chicago in 2024 alongside Steven Wilson, Michael Kopech and Jordan Leasure. However, with the acquisition of Wilson and Kopech's move from starter to reliever, Brebbia has become less interesting as a candidate for saves in Chicago's bullpen, especially since he's also hurt.

The Los Angeles Dodgers' interpreter for two-way superstar Shohei Ohtani was fired on Wednesday after questions surrounding at least $4.5 million in wire transfers sent from Ohtani's bank account to a bookmaking operation set off a series of events. Ippei Mizuhara incurred gambling debts to a bookmaking operation that is under federal investigation, according to multiple sources. Mizuhara was accused by Ohtani's attorneys of engaging in a "massive theft" of Ohtani's funds. Multiple sources told ESPN that Ohtani does not gamble, and the funds covered Mizuhara's losses. The federal investigation is ongoing, but it appears that Ohtani is innocent in all of this and never bet on sports, so this incident shouldn't leave him open to any kind of discipline from Major League Baseball.

Kansas City Royals right-hander Alec Marsh has made a strong impression in spring training, giving up three runs in 14 Cactus League innings, and might be considered the favorite for the fifth and final starting rotation spot to enter the season. Jordan Lyles is the incumbent behind Cole Ragans, Seth Lugo, Brady Singer and Michael Wacha, but he's been slowed in camp with lower-back tightness and it's unclear if he'll be built up to 90-plus pitches by Opening Day next week. Daniel Lynch IV is healthy and has also looked good this spring, though, and Anthony Veneziano is another candidate in the conversation as he continues to build up as a starter. The 25-year-old Marsh, a former second-rounder in 2019 out of Arizona State, went 3-9 in his rookie year in 2023 with a 5.69 ERA and 1.56 WHIP with 39 walks and 85 K's in 74 1/3 innings over 17 games (eight starts).
