San Diego Padres outfielder Fernando Tatis Jr. (illness) is expected to make his Cactus League debut on Friday against the Seattle Mariners, as well as most of the regulars for the Padres, according to manager Mike Shildt. Tatis had been away from the team for a few days while dealing with the flu before returning to camp on Wednesday. The 26-year-old will have a light day on Thursday before playing in his first game on Friday. The Dominican outfielder missed substantial time last year due to a stress reaction in his right quadriceps, but he still managed to hit .276/.340/.492 with an .833 OPS, 21 home runs, 49 RBI, 11 stolen bases and 64 runs scored in 102 regular-season games. With better health in 2025, Tatis' stolen base numbers should be back on the rise, and his power/speed upside make him a top-15 fantasy selection in 2025 drafts.

Tampa Bay Rays infielder Jose Caballero (foot) fouled a ball off his foot in Thursday's Grapefruit League game against the Detroit Tigers and left the contest, according to the Tampa Bay Times' Marc Topkin. Caballero will surely go for testing to determine whether he's dealing with a serious injury, so stay tuned for more news later on Thursday. The 28-year-old native of Panama led the league with 44 stolen bases and was also caught a league-leading 16 times while slashing .227/.283/.347 with nine home runs, 44 RBI and 53 runs scored in 139 games and 483 plate appearances in his first season with the Rays. He's mainly attractive to fantasy managers for his positional versatility and his wheels on the basepaths. With Junior Caminero expected to be a regular starter in 2025, it's possible that Caballero becomes more of a utility infielder in 2025, which would obviously be a big hit to his fantasy value.

San Diego Padres right-hander Dylan Cease will make his Cactus League debut on Saturday against the Cincinnati Reds, according to MLB.com's AJ Cassavell. Cease was the subject of trade rumors in the offseason as he heads into the final year of his contract, and although it appears the 29-year-old will stick with the Friars to begin the 2025 regular season, he could get moved closer to the deadline this summer. In his first year with the Padres in 2024 after being acquired in a trade from the Chicago White Sox, Cease went 14-11 with a 3.47 ERA (3.10 FIP), 1.07 WHIP, 224 strikeouts and 65 walks in 189 1/3 innings over 33 starts in the regular season. He has now fanned 200-plus hitters in four straight seasons and also had a career-best 8.5 percent walk rate last year. The ace of San Diego's staff should be viewed as a low-end fantasy ace/high-end No. 2 in 2025.

Chicago White Sox shortstop prospect Colson Montgomery (back) was scratched from Thursday's Cactus League lineup against the division-rival Cleveland Guardians for precautionary reasons due to back spasms, according to MLB.com's Scott Merkin. Montgomery is considered day-to-day. It's not a serious injury, but it's something to keep an eye on with the 23-year-old, who is considered by MLB Pipeline to be the No. 39 overall prospect entering the 2025 season. While he hasn't exactly turned heads with his production in the minor leagues and doesn't have high-end speed, he could easily be considered Chicago's shortstop of the future, perhaps due to lack of better options. The 6-foot-3, 225-pounder does get on base often and has intriguing power. Montgomery should already be stashed in dynasty leagues and is worth a late-round flier in deep-mixed and AL-only leagues.

Although nothing is finalized, Los Angeles Dodgers manager Dave Roberts said Japanese right-hander Roki Sasaki could "potentially" make his Cactus League debut on Tuesday night against the Cincinnati Reds. The news comes after Sasaki had a three-inning simulated game against Chicago White Sox hitters on Tuesday in which he allowed two home runs. The 23-year-old rookie is expected to start on March 19 in the second game of the season in Tokyo, Japan, against the Chicago Cubs, although he could be on a short leash in that one and early on in his first year in the big leagues. Sasaki will be fantasy relevant in all leagues in his first taste of major-league hitters and he features a nasty splitter. There's definitely ace upside here, but durability could be an issue since he hasn't thrown more than 129 1/3 innings in a season while dealing with some injuries. He'll be a risk/reward low-end No. 2 fantasy starter in his rookie season.
