Lee (2-0) tossed 1.1 scoreless innings of relief to earn the win in Sunday's 1-0 victory over the Royals. He struck out one.

After Detroit starter Keider Montero went 4.2 innings, Lee was asked to face four batters in the middle innings, and he retired all four on only 12 pitches. The rookie righty has been effective with a 1.15 ERA, 0.77 WHIP and 15 strikeouts across 15.2 innings. Lee could see his role in the Tigers' bullpen continue to grow as the season progresses based on his promising early results.

Vest threw a perfect ninth inning to earn the save in Sunday's 1-0 win over the Royals.

Vest needed just nine pitches to secure his second save of the weekend. The right-hander has allowed only two earned runs over his past 10 appearances and has now converted five straight save chances. On the season, he's 9-for-11 in save opportunities with a 1.93 ERA, 1.04 WHIP and 29:9 K:BB across 28 innings.

The Yankees optioned De Los Santos to Triple-A Scranton/Wilkes-Barre on Sunday.

The right-hander pitched the first two games of the series versus the Dodgers and will be sent down Sunday in favor of a fresh bullpen arm. De Los Santos has given up just four earned runs across 12 innings with the Yankees this season, but his 1.92 WHIP and 9:6 K:BB provide a less optimistic outlook.

Cousins (forearm/pectoral) is expected to begin a rehab assignment Tuesday, Gary Phillips of the New York Daily News reports.

Cousins has been on the shelf for the entirety of the 2025 season after suffering a forearm strain in February. The right-hander was on the cusp of returning to action in mid-May, but he sustained a pectoral injury, which slowed his progress. Considering the amount of time Cousins has missed, he'll likely require a handful of appearances on his rehab assignment, and it's currently unclear what level of the Yankees' minor-league system he'll report to.

Baker earned the save in Sunday's 3-2 win over the White Sox, striking out two in a perfect ninth inning.

With both Felix Bautista and Seranthony Dominguez seemingly unavailable, Baker was tasked with protecting a one-run lead in the ninth inning Sunday. The right-hander made quick work of the White Sox, needing just 13 pitches to pick up his first save this season. The 30-year-old Baker has been solid in a setup role this year, posting a 2.77 ERA with a 0.92 WHIP and 33 strikeouts across 26 innings.

Chapman earned the save in Sunday's 3-1 win over Atlanta, logging a strikeout and a walk in a scoreless ninth inning.

Chapman has allowed just one run while striking out 10 in his last eight innings, and he improved to 9-for-10 in save chances this season. Overall, the 37-year-old southpaw sports a 1.88 ERA with a 1.00 WHIP and 32:9 K:BB across 24 innings this year.

The Rangers selected Heuer's contract from Triple-A Round Rock on Sunday, Shawn McFarland of The Dallas Morning News reports.

Heuer will receive his first look in the big leagues since 2021 after posting a 3.27 ERA, 1.32 WHIP and 25:11 K:BB across 22 innings with Round Rock. The right-hander will provide the Rangers with some bullpen depth while Nathan Eovaldi (triceps) heads to the injured list.

The Blue Jays reinstated Swanson (forearm) from the 60-day injured list Sunday.

The right-hander has been sidelined for the first couple months of the season due to carpal tunnel syndrome in his right forearm, but he's ready to rejoin the Blue Jays after a six-outing rehab assignment with Triple-A Buffalo. Swanson had a 5.03 ERA across 45 appearances last season, but he recorded four saves and 29 holds with a 2.97 ERA during the regular season in 2023 and could return to a high-leverage role if he can regain that form.

The Red Sox placed Slaten on the 15-day injured list Sunday due to right shoulder inflammation.

According to Chris Cotillo of MassLive.com, Slaten experienced some fatigue after his most recent appearance in Milwaukee on Wednesday, when he took the loss and a blown save after giving up two unearned runs in one-third of an inning. The right-hander will be eligible to be reinstated June 13, and he could be ready to rejoin the Red Sox at that point since his injury doesn't appear to be overly serious.

The Red Sox recalled Guerrero from Triple-A Worcester on Sunday.

He'll be joining the bullpen as a replacement for right-hander Justin Slaten (shoulder), who was placed on the 15-day injured list in a corresponding move. Guerrero had two stints with the big club earlier this season, making four relief appearances while logging a 1.69 ERA and 1.13 WHIP over 5.1 innings. Expect the Red Sox to use him primarily in lower-leverage spots.
