Rosenberg completed an inning in relief against Houston on Monday, allowing a run on two hits and a walk while striking out two.

The southpaw had his contract selected earlier in the day and was brought in to make his big-league debut with the Astros up by four runs in the eighth inning. Rosenberg struck out the first batter he faced before allowing the next three hitters to reach base on a walk and two singles. The outing wasn't entirely bad for the reliever, as he notched four swings-and-misses and struck out two. Rosenberg figures to be used primarily in low-leverage spots while he remains up with the big club.

Thompson scooped up the win in relief during Monday's 4-2 victory over the Rays after striking out five and allowing one hit and one walk over 3.2 scoreless innings.

Heading into the season, Thompson looked as though he might serve as the Cubs' No. 5 starter with all of Wade Miley (elbow), Alec Mills (back) and Adbert Alzolay (lat) on the injured list, but manager David Ross may prefer to keep the 27-year-old right-hander in his current role as a multi-inning fireman out of the bullpen. He's been fantastic through three appearances, scooping up two wins and working 9.2 scoreless frames in total while permitting only seven baserunners and striking out 10. Predicting when he might be used could be difficult, however, so Thompson's fantasy value is mostly contained to NL-only or deeper mixed leagues for the time being.

Bickford picked up a hold Monday against Atlanta, allowing one hit in one scoreless inning.

Bickford started the season in the minors after having his spring schedule delayed by arm soreness, and he was called up to the big club Sunday. He was sharp in his first big-league outing of the campaign Monday, throwing 13 of 16 pitches for strikes and allowing only an infield single. The right-hander enjoyed a breakout season with Los Angeles last season and figures to play a significant role in the team's bullpen now that he is back to full health.

Hall, who has not pitched in a game this season, was transferred from Double-A Bowie to the development list April 8.

Hall's electric stuff is unquestioned, but his strike throwing and durability issues have led to some projecting a future home in the bullpen. Perhaps he is working on his command/control in extended spring training before heading out to a full-season league, as he only threw 31.2 innings in 2021 and will have to have his workload managed this season anyway.

Marte won't be called up from Triple-A Sacramento for Tuesday's doubleheader with the Mets, as the Giants have instead designated utility man Luke Williams as their 29th man for the twin bill, Evan Webeck of The San Jose Mercury News reports.

After he joined the Giants in Washington earlier Tuesday, Marte was expected to be added to the roster for the twin bill, but he'll instead remain on the taxi squad for the club's East Coast road trip. Marte will presumably be first in line for a promotion if the Giants need an extra reliever at any point.

The Giants will recall Marte from Triple-A Sacramento to serve as the team's 29th man for Tuesday's doubleheader with the Nationals, Alex Pavlovic of NBC Sports Bay Area reports.

Less than a week after being optioned to Sacramento, Marte is rejoining the Giants, but he's expected to be up with the big club for only a day before returning to the minors. Marte will give the Giants an extra arm out of the bullpen for the twin bill, but he'll likely be ticketed for lower-leverage work.

The Nationals will call up Perez from Triple-A Rochester ahead of the second game of Tuesday's doubleheader with Arizona, Jesse Dougherty of The Washington Post reports.

Perez will be designated as Washington's 29th man for the twin bill and gives the club an extra left-hander in the bullpen, though he's unlikely to see high-leverage innings. The 24-year-old allowed three runs in 6.2 innings in his MLB debut season for Cleveland in 2021.

The Diamondbacks plan to call up Gilbert from Triple-A Reno to start the second game of Tuesday's doubleheader with the Nationals, Jody Jackson of Bally Sports Arizona reports.

Arizona is likely to make the transaction official following the front end of the doubleheader, with Gilbert expected to be designated as the Diamondbacks' 29th man for the twin bill. Gilbert notably tossed a no-hitter against the Padres in his MLB debut a season ago, but his 3.15 ERA and 1.02 WHIP over 40 innings with the big club was supported by poor peripherals (7.6 K-BB%, 38.6 percent groundball rate, 5.09 xFIP). He'll likely be headed back to Reno after his spot start Tuesday.

Peters allowed one walk while striking out three without surrendering a hit or a run across three innings Monday against Milwaukee.

Peters entered the game in the fifth inning, after Zach Thompson was roughed up for six earned runs. He delivered three strong innings as a bulk reliever out of the bullpen and now has seven scoreless frames of work across his three appearances on the season. Peters served as a starter for Pittsburgh in 2021, and it's possible he returns to that role at some point in the new campaign.

Manager Dave Roberts said Monday after the Dodgers' 7-4 win over Atlanta that Treinen won't be available for the final two games of the series due to an arm issue, Fabian Ardaya of The Athletic reports.

Roberts noted that Treinen's arm was "barking" after his appearance in the Dodgers' home opener last Thursday, which is why the reliever hasn't been used since. Fortunately, the skipper relayed that Treinen felt fine while playing catch Monday and is on track to avoid the injured list, but the Dodgers will play it safe by keeping him out a few more days. Treinen is expected to be ready to go when the Dodgers open a three-game series in San Diego on Friday.
