Seattle Mariners right-hander Gregory Santos (lat) is a little bit behind the other pitchers in spring training due to a right-lat that has recently surfaced. Santos won't be able to throw off a mound right away in camp. The 24-year-old also dealt with right-elbow soreness last year and could be in danger of opening the 2024 regular season on the injured list. Santos came to Seattle this offseason in a trade from the Chicago White Sox and figures to serve in a setup role when healthy. The Dominican reliever made a career-high 60 appearances out of Chicago's bullpen last year and was solid with a 3.39 ERA and 1.29 WHIP with his first five career saves, 17 walks and 66 strikeouts in 66 1/3 innings. Unless injuries in the back of Seattle's bullpen open up save chances for Santos, he's unlikely to have much fantasy appeal in 2024.

Chicago White Sox right-hander Davis Martin's (elbow) rehab from Tommy John surgery has gone well. His body and arm are feeling good and he is scheduled to start throwing bullpen sessions next Monday. The 27-year-old hurler went under the knife last May and continues to work his way back for the 2024 season. He will open the regular season on the injured list and probably isn't going to be able to join Chicago's bullpen until the second half of the year. Martin made his big-league debut with the Pale Hose in 2022 and had a 4.83 ERA (4.28 FIP) and 1.29 WHIP with 19 walks and 48 strikeouts in 63 1/3 innings over 14 appearances (nine starts). Given his long layoff, Martin is most likely to return to Chicago as a reliever once he's ready to make his season debut in 2024.

New York Yankees right-hander Lou Trivino (elbow), who re-signed with the club on Wednesday, said that he hopes to be back "at some point in the middle of the season" after undergoing Tommy John surgery to fix a torn UCL last May. Trivino has already been throwing bullpen sessions and is feeling good. The 32-year-old's deal with the Yankees includes an option for the 2025 season. He started last year with the Oakland Athletics before finishing with the Yankees, going a combined 2-8 with a 4.53 ERA (3.63 FIP), a 1.64 WHIP, 11 saves, 24 walks and 67 strikeouts in 53 2/3 innings pitched. Ten of his 11 saves came in Oakland, but he was better overall with the Yankees with a 1.66 ERA in 21 2/3 innings pitched. Trivino is off the fantasy radar.

Doctors performed an arthroscopy/cleanup on Colorado Rockies right-hander Daniel Bard's left knee on Wednesday and did not need to do a meniscus repair as originally believed. The general recovery time frame is one month, which is a little less than the five to seven weeks the team originally believed he'd have to miss. It's good news for the 38-year-old reliever, but he still seems likely to open the 2024 season on the injured list. Bard could be in the mix for saves in Colorado when he's healthy, and at the very least he'll be a candidate for consideration in deep holds leagues, but the Rockies probably won't give their relievers many save chances. He had 54 saves in 2021 and 2022 but is an extremely risky reliever because of his past history with anxiety and the yips.

Miami Marlins right-hander Sixto Sanchez (shoulder) told the media on Thursday at spring training that he feels 90 to 95 percent ready to go for the 2024 season. We'll believe it when we see it. Sanchez made his first appearance since 2020 in a rehab game with Double-A Pensacola last September but was then shut down shortly after that due to more shoulder issues. The 25-year-old is trending in the right direction in spring training this year, but fantasy managers should be highly skeptical as to whether he will be able to hold up over the course of a full season again. The Dominican hurler made seven starts in his MLB debut in 2020 and went 3-2 with a 3.46 ERA and 1.20 WHIP with 11 walks and 33 strikeouts in 39 innings. Sanchez has age on his side, but he should open the year on the waiver wire in most single-year fantasy formats.
