Guerra was designated for assignment by the Padres on Tuesday.

Guerra surrendered four earned runs over two innings during his lone appearance of the season Sunday against the Diamondbacks, and he won't retain his spot on the Friars' 40-man roster. San Diego claimed Kyle Tyler off waivers in a corresponding move.

Robertson pitched a scoreless ninth inning to earn the save in Tuesday's 2-1 win over the Pirates.

Robertson has now recorded each of the Cubs' first two saves of the season, so it looks like he's ahead of Rowan Wick and others in the bullpen pecking order. Manager David Ross may still mix and match depending on matchups moving forward, but the veteran righty appears to be the preferred Chicago reliever from a fantasy perspective at the moment.

Kranick (forearm) is scheduled to make a rehab start Tuesday for Low-A Bradenton.

Kranick didn't see any action during the Grapefruit League slate while he recovered from a right forearm strain, so Tuesday's outing will likely be the first of multiple rehab appearances for the 24-year-old before he's activated from the 10-day injured list. The time Kranick missed along with the fact that he has minor-league options remaining likely means that he'll be sent to Triple-A Indianapolis once reinstated, though the organization's plans for him could change if the big club has an opening in the rotation a few weeks down the road.

Marte was called up by the Giants on Tuesday, Maria I. Guardado of MLB.com reports.

The 27-year-old has yet to make his major-league debut. In 87 career innings at the Triple-A level, he owns a 4.14 ERA and 1.48 WHIP, striking out 26.9 percent of opposing batters while walking 9.5 percent. He'll replace Tyler Rogers, who landed on the paternity list, though Marte will likely be limited to low-leverage work.

Rogers was placed on the paternity leave as expected Tuesday, Maria I. Guardado of MLB.com reports.

Rogers took the loss against his twin brother Taylor's Padres on Monday and will now be unavailable for a few days. He'll likely return during the weekend series in Cleveland. Yunior Marte was recalled to take Rogers' place on the roster.

May said Tuesday that he doesn't think he'll require a stint on the 10-day injured list after an MRI on his arm revealed a "very, very low-grade triceps strain," Anthony DiComo of MLB.com reports.

The Mets will stay away from May for the remaining two games of its series in Philadelphia, but he appears to have steered clear of any major damage after experiencing arm fatigue during his appearance in Monday's 5-4 loss to the Phillies. After getting a couple days of rest and anti-inflammatory treatment to address the injury, May will be re-evaluated on Thursday's off day. Assuming he shows the desired improvement, he should be available for this weekend's home series versus the Diamondbacks.

Webb was designated for assignment by Atlanta on Tuesday, David O'Brien of The Athletic reports.

Webb failed to make the Opening Day roster and has now lost his spot on Atlanta's 40-man roster. The 28-year-old had a 1.39 ERA, 1.11 WHIP and 28:12 K:BB over 32.1 innings during 2019, but he had a 4.19 ERA and 1.51 WHIP last year. Atlanta selected the contract of Jackson Stephens in a corresponding move.

Sims (elbow) will begin a rehab assignment with Triple-A Louisville on Tuesday.

Sims has been behind schedule since the start of camp after dealing with elbow and back issues over the winter, though the Reds never seemed to be concerned about any long-term absence. He looked like the favorite to close heading into spring training but was never officially named the closer, so his role upon his return is not yet clear. Tony Santillan and Art Warren have picked up the Reds' two saves so far this season.

Diaz was activated off the bereavement list Tuesday, Mike Puma of the New York Post reports.

The Mets' bullpen struggled in Diaz's absence, with Trevor May (arm) and Seth Lugo combining to allow five runs in the eighth inning Monday against the Phillies, leading to a loss. Diaz should immediately reclaim the closer role upon his return.

Lamet has made one relief appearance across the Padres' first five games, retiring the lone batter he faced en route to earning a hold in San Diego's April 8 win over Arizona.

The Padres' decision to trade away starter Chris Paddack on Opening Day didn't change Lamet's outlook, as the 29-year-old is still beginning the season in a relief role. Lamet has thrown just one pitch so far this season, but Jeff Sanders of The San Diego Union-Tribune relayed that the right-hander threw at least a couple dozen of pitches while warming up in the bullpen in each of the last three contests. Manager Bob Melvin acknowledged after Monday's 4-2 win over the Giants that he needed to vary his reliever usage a bit, so it's possible that Lamet could gain some traction in a setup role in front of closer Taylor Rogers in the coming days.
