The Cardinals placed Robertson on the 15-day injured list Sunday due to right elbow inflammation, Jeff Jones of the Belleville News-Democrat reports.

Robertson was promoted to the big club April 21 after registering a 2.84 ERA and 1.31 WHIP over 6.1 innings with Triple-A Memphis. He's appeared in eight games for the Cardinals this season and has a 4.38 ERA, 1.38 WHIP and 14:2 K:BB over 12.1 innings out of the bullpen. With Robertson on the shelf, St. Louis recalled right-hander Andre Pallante from Triple-A Memphis in a corresponding move.

The White Sox claimed Peralta off waivers and optioned him to Triple-A Charlotte on Sunday.

After being designated for assignment by the Mariners on Thursday, Peralta returned to the White Sox organization Sunday, re-joining a team he started the season with. The 26-year-old left-hander will stay in the minors, where he has a 9.24 ERA and 1.97 WHIP across 12.2 innings in Triple-A.

The Giants optioned Avila to Triple-A Sacramento on Sunday.

Avila will cede his spot on the 26-man active roster to left-hander Blake Snell (personal), who was reinstated from the paternity list. The 26-year-old Avila has made eight relief appearances for the Giants this season, logging an 8.49 ERA and 1.71 WHIP across 11.2 innings.

Tate (2-0) pitched 2.1 perfect innings and struck out four to earn the win over the White Sox on Saturday.

Tate was locked in for a long-relief appearance, and the Orioles were able to pull ahead while he was in the game. The right-hander had spent nearly a month at Triple-A Norfolk, posting a 3.86 ERA, 0.71 WHIP and 5:0 K:BB over seven innings. The Orioles have dealt with a rough stretch of pitching injuries recently, so Tate is up as a reinforcement in the bullpen. He has a 2.40 ERA, 0.87 WHIP and 10:6 K:BB over 15 innings in the majors this season, and it looks like he could provide some length when necessary.

Jackson (3-1) earned the extra-inning win Saturday over the Mets, allowing one walk over a scoreless and hitless inning.

All three of Jackson's wins have come over his last seven appearances despite the reliever giving up five runs across six innings in that span. It's been a case of him being in the right place at the right time, especially with the Giants' recent inclination to comeback wins. Jackson is at a 5.40 ERA, 1.65 WHIP and 15:8 K:BB over 13.1 innings while adding two holds and three blown saves through 15 appearances this season.

The Mariners optioned Bazardo to Triple-A Tacoma on Sunday.

Bazardo will give up his spot in the bullpen and on the 26-man active roster to southpaw Tayler Saucedo (knee), who was reinstated from the 15-day injured list in a corresponding move. After getting a call-up from Tacoma on May 8, Bazardo made five relief appearances for Seattle and gave up five earned runs on four hits and four walks over 7.2 innings.

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.
