Nelson was placed on the 15-day injured list with left shoulder inflammation Tuesday.

Nelson will now be sidelined for at least a couple weeks while tending to inflammation in his pitching elbow, which is never good news for a hurler. The 27-year-old had been going through a rough stretch on the mound, surrendering five earned runs over 1.1 innings in his last three appearances. It's unclear if the left-hander's stretch of poor performances had anything to do with potential arm issues or not, but he'll now at least have an opportunity to mentally reset while on the shelf. In a corresponding move, Arizona recalled right-hander Justin Martinez from Triple-A Reno on Tuesday.

The Diamondbacks recalled Martinez from Triple-A Reno on Tuesday.

Martinez appeared in two games with the D-backs before being sent down to Triple-A on Sunday, throwing three scoreless innings while striking out two batters and walking four. He'll give Arizona additional depth in its bullpen as Kyle Nelson (shoulder) lands on the 15-day IL.

The Diamondbacks placed Castro on the 15-day injured list Tuesday, retroactive to April 21, with right shoulder inflammation.

Castro will undergo an MRI on his right shoulder Wednesday, Theo Mackie of The Arizona Republic reports. The reliever was dealing with discomfort for a bit, but it seems to have gradually gotten worse. He surrendered two runs on four hits across one inning during his last appearance Saturday. The 29-year-old is eligible for activation May 6, a team off day before the start of a series against the Reds. In a corresponding move, Andrew Saalfrank was recalled from Triple-A Reno.

Garrett (shoulder) threw a 25-pitch side session Tuesday and is scheduled to pick up his rehab assignment Friday with Triple-A Jacksonville, Christina De Nicola of MLB.com reports.

The left-hander is ready to resume his rehab assignment after a bout of dead arm slowed the progress in his return from a pinched nerve in his left shoulder. Garrett threw 86 pitches in his previous rehab outing April 12 and is scheduled to throw about 60 pitches or four innings Friday. The 26-year-old seems likely to require an additional rehab start after Friday before making his season debut for Miami.

The Diamondbacks recalled Saalfrank from Triple-A Reno on Tuesday.

The left-hander missed out on Arizona's Opening Day roster but will join the big club Tuesday as Miguel Castro (shoulder) moves to the injured list. Saalfrank made his MLB debut with 10 relief appearances last season and didn't allow an earned run over 10.1 innings.

The Diamondbacks recalled Henry from Triple-A Reno ahead of his start against the Cardinals on Tuesday.

The 26-year-old was demoted to Reno on April 17 after he posted a 6.87 ERA, 1.80 WHIP and 18:8 K:BB in his first four starts of the season, but he'll rejoin the Diamondbacks for another start Tuesday. Henry could stick in the rotation with a strong performance since Ryne Nelson (elbow) and Merrill Kelly (shoulder) are on the injured list.

The Diamondbacks placed Kelly on the 15-day injured list Tuesday with a right shoulder strain.

Kelly was diagnosed with a teres major strain of his right shoulder following an MRI. He had been scheduled to start this past Sunday's series finale in San Francisco, but he was scratched after experiencing discomfort prior to the game. The Diamondbacks were initially hopeful the 35-year-old would avoid a stint on the IL, but that naturally went by the wayside with Tuesday's development. In a corresponding move, Tommy Henry was recalled from Triple-A Reno and should step into Kelly's spot in the rotation.

The Giants optioned Roupp to Triple-A Sacramento on Tuesday, Maria I. Guardado of MLB.com reports.

Roupp will be pushed off the big-league roster following the acquisition of Mitch White from Toronto. Roupp allowed five earned runs across 10.1 innings during his first career stint in the majors and could return later in the year to give San Francisco's bullpen a fresh arm if needed.

Dodgers manager Dave Roberts said Tuesday that Heyward (back) is still experiencing "residual soreness" and isn't yet swinging a bat, Fabian Ardaya of The Athletic reports.

The veteran outfielder hoped to return when first eligible after he landed on the 10-day injured list April 3 with back soreness, but he's still having issues nearly three weeks later. Heyward will need some time to build back up once cleared to swing before starting a rehab assignment, so he's likely at least a few weeks away from rejoining the Dodgers.

Rockies manager Bud Black said Tuesday that Bryant (back) is not participating in baseball activities and won't be reinstated from the 10-day injured list when first eligible Wednesday, Patrick Lyons of JustBaseball.com reports.

There apparently isn't much concern about the back strain being a serious issue since Bryant hasn't been sent for medical imaging, but the lower-back strain will still keep him sidelined for the near future. The 32-year-old doesn't have an official timeline for his return and should be considered out indefinitely until he resumes baseball activities.
