The Minnesota Twins have activated right-hander Jhoan Duran (oblique), who has missed the start of the season due to an oblique injury. Last season, the right-hander had 27 saves with a 2.45 ERA. Duran is one of the top closers in fantasy baseball and is expected to resume his role as the closer after his two-game rehab stint in Triple-A, as his fastball clocked in at an average of 101.8 mph. In a corresponding move, the Twins have designated right-hander Matt Bowman for assignment. Bowman had a 2.35 ERA in five games in 7 2/3 innings, allowing two runs out of the bullpen.

Houston Astros outfielder Chas McCormick is dealing with soreness in his hamstring. Astros manager Joe Espada said it is a day-to-day injury for the time being. McCormick is slashing .236/.325/.278 this season with 8 RBIs. With McCormick out of the lineup, Joey Loperfido will be getting some starts in the outfield, the manager revealed. Loperfido was expected to play some first base due to the struggles of Jose Abreu, but will now get some reps in the outfield due to the injury to McCormick. In the minors, Loperfido slashed .287/.393/.713 with 13 home runs in 25 games before the callup and is a fantasy option due to his power.

The Colorado Rockies placed outfielder Nolan Jones (back) on the 10-day injured list (retroactive to April 29) with a lower-back strain. With Jones going to the IL, Colorado selected the contract of outfielder Jordan Beck to the major league roster, and left-hander pitcher Lucas Gilbreath has been transferred to the 60-day injured list. This season, Jones is slashing .170/.243/.277 with one home run, as he last played on April 28 and went 1-for-2 with one strikeout. Beck is the Rockies No. 4 prospect, per MLB pipeline, will likely play everyday while Jones is on the IL.

The St. Louis Cardinals moved starting pitcher Drew Rom (biceps) to the 60-day injured list on Tuesday to make room for pitcher Kyle Leahy as the 27th man for Tuesday's doubleheader against the Detroit Tigers. Rom is dealing with a left-biceps injury and is scheduled to visit with Dr. Keith Meister in Dallas on Tuesday. Now that the 24-year-old left-hander is on the 60-day injured list, he won't be eligible to return to the Cardinals' bullpen until at least late May. The former fourth-round selection by the Baltimore Orioles in 2018 went 1-4 in his big-league debut in St. Louis last year and had a rough 8.02 ERA (5.75 FIP) and 2.08 WHIP with 19 walks and 32 strikeouts in 33 2/3 innings over his eight starts. Rom showed plenty of strikeout potential in the minors, but his control has also been lacking.

The Chicago White Sox signed first baseman Jared Walsh to a minor-league deal on Tuesday. He will report to Arizona before being assigned to Triple-A Charlotte. Walsh began the year with the Texas Rangers and went 12-for-53 (.226) with a home run, seven RBI and nine runs scored in 17 games while filling in at first base with Nathaniel Lowe starting the year on the injured list. Once Lowe returned from his injury, the Rangers cut Walsh. At this point, the White Sox are just looking for warm bodies with potential. For the time being, the 30-year-old Walsh will provide minor-league depth at first base. The former 39th-round pick by the Los Angeles Angels in 2015 out of Georgia has a career .239/.301/.438 slash line with 59 home runs and 191 RBI in six seasons, including this year.
