San Francisco Giants left-handed pitcher Erik Miller (illness) made his spring training debut on Saturday against the Kansas City Royals. Miller allowed one hit and hit a batter but did not allow a run. He tallied all three of his outs via strikeouts. The 27-year-old initially dealt with a minor finger injury during camp but then came down with an illness that extended his absence. Fantasy managers should continue to monitor his stats but should not expect the 27-year-old to face many restrictions during the remainder of camp. Last summer, Miller made his MLB debut and held a 3.88 ERA with a 1.31 WHIP across 67 1/3 innings of work. He tallied 87 strikeouts but posted a high 13.4 percent rate. Miller generated an impressive 3.14 xERA with a .190 xBA, suggesting he should face some positive regression in 2025. During the regular season, he should compete for a high-leverage role in the bullpen.

Houston Astros first baseman Christian Walker (oblique) will not swing a bat for a few days. However, he was seen running and stretching with the team earlier on Sunday. Walker underwent an MRI on his oblique after being scratched from Wednesday's lineup. However, he did not suffer a strain and the diagnosis provided "relatively good news." Fantasy managers should continue to monitor his status but he is currently on track to not miss any time during the regular season. Earlier in the offseason, the Astros signed Walker to a three-year $60 million contract. The 33-year-old has spent the majority of his MLB career in Arizona after playing his first two seasons in Baltimore. Last summer, Walker posted a .251/.335/.468 slash line with 26 doubles and 26 home runs. When healthy, he should bat in the heart of the Houston lineup which should provide him with elite RBI opportunities.

Houston Astros starting pitcher Lance McCullers Jr. (forearm) will throw his final live bullpen session on Wednesday before making his spring debut. McCullers has been sidelined since the 2022 season since undergoing surgery to repair a torn flexor tendon and remove a bone spur from his right forearm. However, it appears McCullers is nearing the end of his lengthy recovery process. Fantasy managers should continue to monitor his status after Wednesday's bullpen session as he could be cleared to make his spring debut shortly after. Even though the 31-year-old will open the season on the injured list, he may not miss much time in the regular season given his current status. In the 2022 season, the 31-year-old logged 47 2/3 innings with a strong 2.27 ERA with a 1.24 WHIP. When he does return to the bump, he should have a role in the starting rotation.

The New York Mets have optioned right-handed pitcher Kevin Herget to Triple-A Syracuse. The Mets claimed Hergert off waivers earlier in the offseason but he was unable to capture a spot on the Opening Day roster. Last season, Hergert tossed 11 1/3 innings with the Milwaukee Brewers and held a strong 1.59 ERA with a 0.79 WHIP. He tallied nine punchouts and posted a strong 7.9 percent walk rate. However, in 2023, Hergert posted a higher 5.18 ERA with a 1.32 WHIP across 24 1/3 innings with the Cincinnati Reds. Last season, the 33-year-old logged 47 2/3 innings at Triple-A and held a solid 2.27 ERA with a 0.94 WHIP. He held an 11:59 BB:K ratio and allowed just two home runs. Fantasy managers in deeper formats should expect Hergert to return to the majors when the Mets need additional depth in their bullpen.

Chicago White Sox shortstop prospect Colson Montgomery (back) is returning to the starting nine on Sunday to face the Cleveland Guardians. Montgomery will cover shortstop and bat in the six-hole. The top prospect in the Chicago system has been sidelined since the end of February due to back spasms. Given his missed time, fantasy managers should expect him to open the season at the Triple-A level. Last season, the former 22nd overall pick in the 2021 MLB Draft spent his entire campaign with Triple-A Charlotte and held a .214/.329/.381 line with 21 doubles and 18 home runs. He struggled to find consistency throughout the season but did begin to turn the corner in September as he posted a .223/.336/.401 line with four long balls. If the team were to send Montgomery to Triple-A at the start of the season, Brooks Baldwin will see most of the starting opportunities at shortstop in the majors.
