The Mariners reinstated Saucedo (knee) from the 15-day injured list Sunday.

He'll take over the 26-man active roster spot of right-hander Eduard Bazardo, who was optioned to Triple-A Tacoma in a corresponding move. Saucedo was placed on the IL on May 8 with a hyperextended right knee but looks to be healthy again after he tossed a scoreless inning in his lone rehab appearance for Tacoma on Thursday.

The Red Sox optioned Kelly to Triple-A Worcester on Sunday, Mac Cerullo of the Boston Herald reports.

Kelly will head back to Worcester to make room in the bullpen for right-hander Brad Keller, who agreed to a one-year deal with the Red Sox. After making his return from Triple-A on April 24, Kelly made 11 relief appearances for Boston and logged a 2.16 ERA and 1.26 WHIP across 16.2 innings.

Keller signed a one-year contract with the Red Sox on Sunday, Mac Cerullo of the Boston Herald reports.

After clearing waivers upon being designated for assignment by the White Sox last week, Keller elected free agency and quickly caught on with a new club on a big-league deal. Keller is expected to be available out of the bullpen for Sunday's game against the Brewers and should serve as a long-relief option for the duration of his stay with Boston. Prior to being cut by the White Sox, Keller made five appearances (two starts) and pitched to a 4.86 ERA and 1.38 WHIP across 16.2 innings.

Alexander was credited with his first hold in Saturday's win over the Astros, firing a scoreless two-thirds of an inning.

Alexander got the final two outs of the eighth, inheriting a one-on, one-out situation from Lucas Erceg and retiring the dangerous duo of Kyle Tucker and Yordan Alvarez on groundouts. The veteran southpaw allowed a solo home run over two-thirds of an inning in his delayed season debut against the Rockies on Tuesday, but he's subsequently fired 1.2 scoreless, hitless frames in his next pair of appearances.

Speier (0-2) was charged with the loss against the Nationals on Saturday, allowing two earned runs on two hits over one-third of an inning.

Entrusted with preserving a 1-1 tie when he entered in the seventh, Speier induced an inning-opening groundout from Luis Garcia before surrendering back-to-back singles to Jesse Winker and Keibert Ruiz, as well as a steal to the former. Trent Thornton took over at that point and subsequently allowed both inherited runners to score, leading to Speier eventually being charged with the loss. The 29-year-old Speier has now turned in three straight outings where he's allowed two earned runs while recording just one out, and he's conceded 10 runs overall across four innings in May. The veteran southpaw was a reliable bullpen fixture over the previous three seasons for the Royals and Mariners, but his current struggles may be exhausting the slack his previous body of work has earned him.

The Rangers designated Anderson for assignment Sunday.

He'll cede his spot on the 40-man roster and 26-man active roster to right-hander Gerson Garabito, whose contract was selected from Triple-A Round Rock ahead of his scheduled start Sunday against the Twins. After being called up from Round Rock on May 15, Anderson proceeded to make a pair of relief appearances for the Rangers, giving up two earned runs on six hits and one walk while striking out three over 3.1 innings.

Holmes picked up the save over the Padres on Saturday, pitching a perfect ninth inning while striking out one.

Holmes made it look easy Saturday, retiring all three batters he faced in the ninth on a total of just seven pitches to record his 15th save of the season. The right-handed reliever has now converted his last two save opportunities after surrendering four runs to the Mariners on May 20, striking out at least one batter in each of those appearances. Holmes sits just one save behind Emmanuel Clase (16) for the American League lead after Saturday's outing.

Clase picked up the save over the Angels on Saturday, allowing one hit over one inning while striking out two.

Clase entered the game with a one-run lead in the bottom of the ninth and surrendered a leadoff single to Logan O'Hoppe before retiring the next three batters in succession, with two of them going down on strikes. It marked Clase's third appearance this month in which he's registered multiple strikeouts and he's now converted each of his last three save opportunities. The right-hander currently sits at 16 saves on the season, which ties him for the major league lead with Ryan Helsley.

Kopech (1-4) blew the save and took the loss Saturday, giving up three runs on three hits in two-thirds of an inning as the White Sox fell 5-3 to the Orioles. He struck out one.

Chicago rolled into the eighth inning with a 3-0 lead, but after Jordan Leasure served up a two-run homer to Ryan O'Hearn, Kopech got the call and threw more gas on the fire, getting taken deep himself by Anthony Santander and Jordan Westburg. Kopech has been tagged for five home runs in 23.2 innings this season, fueling a 4.18 ERA, and his issues keeping the ball in the park have followed him to the bullpen. He'll continue to get the majority of the save chances for the White Sox, but his reliability as a high-leverage reliever is still in question.

Perez struck out one in a perfect ninth inning Saturday to record his first save of the season in a 5-3 win over the White Sox.

Craig Kimbrel, Danny Coulombe and Yennier Cano had all pitched both Thursday and Friday, leaving manager Brandon Hyde without any of his usual late-inning options when Baltimore took the lead in the eighth. Perez stepped up with a strong performance, needing only 10 pitches (six strikes) to retire the bottom of Chicago's order. The 28-year-old southpaw has an unsightly 5.06 ERA on the season, but he has yet to serve up a homer in 10.2 innings and has blanked the opposition in eight of his 11 appearances while picking up four holds.
