Veteran right-hander Lance Lynn announced his retirement from professional baseball on his wife's podcast on Tuesday, according to the New York Post's Jon Heyman. Lynn was hoping to continue his playing career in 2025 and was even reportedly discussing a deal with the Chicago Cubs, but apparently nothing has come to fruition and he will instead hang up his cleats after 13 years in the big leagues. The 37-year-old was originally drafted in the first round (39th overall) in 2008 out of the University of Mississippi. Seven of his 13 MLB campaigns came in St. Louis, including his last in 2024 in which he went 7-4 with a 3.84 ERA (4.31 FIP) and 1.34 WHIP with 109 strikeouts and 44 walks in 117 1/3 innings over 23 starts. The two-time All-Star will finish his major-league career with a 143-99 record, 3.74 ERA and 1.28 WHIP with 23.7% strikeout rate in 2,006 1/3 regular-season innings. He won a World Series ring with St. Louis in 2011.

The Los Angeles Angels have designated right-handed pitcher Michael Petersen for assignment. This transaction opened a spot for left-handed pitcher Jake Eder, whom the Angels acquired from the Chicago White Sox for cash considerations on Monday. Last season, Petersen made his MLB debut and logged 19 2/3 innings in the majors. He posted a 5.95 ERA with a 1.63 WHIP. He tallied just 14 punchouts and served up a high 11 free passes. He spent most of his 2024 season with Triple-A Oklahoma City and posted a stellar 1.64 ERA with a 0.76 WHIP. He tallied 10 saves and held an 8:44 BB:K. Through the early part of the 2025 Triple-A campaign, Petersen tossed one 1/3 inning with Triple-A Salt Lake and allowed two earned runs. Given his success at Triple-A last summer, he may draw interest on waivers.

The New York Yankees announced on Tuesday that they placed right-hander Devin Williams on the paternity list before their game in the Bronx against the visiting Arizona Diamondbacks. The team also signed right-handed reliever Adam Ottavino to a major-league contract and added him to the active roster. To clear space on the 40-man roster, right-hander JT Brubaker (rib) was transferred to the 60-day injured list. Williams will be away from the Yankees for anywhere from one to three days, so act accordingly with your fantasy lineups. In the meantime, the best bet to fill in for a save chance for the Yankees will be right-hander Luke Weaver. To open his first year with the Yanks, Williams picked up a save on Opening Day last Thursday against his former team, the Milwaukee Brewers, but he also allowed an earned run while walking one and striking out two.

The Athletics have optioned left-handed pitcher Hogan Harris to Triple-A Las Vegas. Harris tallied just one out in the majors during the opening week of the campaign. In a corresponding move, the Athletics claimed left-handed Angel Perdomo on waivers. Last season, the 28-year-old logged 72 1/3 innings in the major leagues and posted a 2.86 ERA with a 1.35 WHIP. He tallied 61 punchouts and served up a high 33 free passes. He generated a modest 5.04 xERA with a .260 xBA, which suggests he will likely see some regression during the 2025 regular season. Across 142 career innings at the Triple-A level, the southpaw posted a high 6.40 ERA with a 1.75 WHIP. During this stint, he served up 94 walks. Fantasy managers should expect Harris to likely return to the majors as a relief option later in the campaign.

Arizona Diamondbacks left-handed pitcher Yu-Min Lin is set to attend extended spring training as he his still ramping up his workload. Lin was unable to participate during most of spring training as he had to return to Taiwan for a military obligation. As a result, the Diamondbacks are opting to slowly increase his workload before the minor league regular season begins to pick up. Fantasy managers should monitor his progression, but he will likely report to Triple-A Reno when he is cleared to return to game action. Last season, the southpaw spent most of his season at Double-A Amarillo, where he posted a 4.28 ERA with a 1.45 WHIP across 94 2/3 innings. Last summer, he logged just four 2/3 innings at Triple-A. If the 21-year-old progresses well at Triple-A, he could push for an MLB debut in the second half of the campaign.
