Carlos Martinez leads a trio of high-profile IL activations...

With Michael Conforto sidelined with a concussion, J.D. Davis is expected to start in left for the Mets. Plus, updates on Zack Greinke, Miguel Andujar, Brendan Rodgers, Anibal Sanchez, Mallex Smith, Jarlin Garcia and Richard Urena.

Shaun Anderson provided the Giants with a very favorable first impression. Plus, Austin Riley coming up, Elvis Andrus placed on IL, Yankees acquire Kendrys Morales, Jeurys Familia returns, Miguel Sano activated, and more.

Gio Urshela gets opportunity at third for Yankees while Andujar is out. Plus, Hiura and Lopez promoted, Urias on administrative leave in LA, Hicks back for NYY, DET activates Harrison, Avila returns to ARI, and more.

With Aaron Hicks ready to make his season debut, either Cameron Maybin or Mike Tauchman will likely be the odd man out. Plus, updates on Felix Hernandez, Corbin Martin, Willians Astudillo, Daniel Mengden, Erik Kratz, Chad Green and more.

Tyler Glasnow's forearm strain opens up a rotation spot in Tampa, though the IP might be divided among several pitchers. Plus, Edwin Jackson joins his 14th MLB team, and Travis D'Arnaud and Aaron Altherr get second chances with new clubs.

The Braves send down A.J. Minter, leaving Luke Jackson as the likely candidate to take over the closer role. Plus, Drew Pomeranz and Mike Zunino hit the IL, and the Mariners call up a pair of infield prospects in the wake of Dee Gordon's injury.

It looks like Jed Lowrie will be up by next week, cutting into PT for Todd Frazier and J.D. Davis. Plus, Steven Matz and Buster Posey land on IL, Max Fried should start Sunday, Christin Stewart back for DET, and PIT makes bullpen moves.

Austin Meadows' return is so likely that the Rays sent Nate Lowe to the minors. Plus, Pedro Strop injury opens door for Steve Cishek and Brandon Kintzler to pick up saves, Gerardo Parra signs with Nats, Derek Holland back with SF, and more.

Mac Williamson is next in line in left for the Giants. Plus, Shohei Ohtani and Matt Olson activated, David Price to the IL, Anthony Rendon back for WAS, Steven Matz dealing with nerve issue, A.J. Pollock's status updated, and more.

With light-hitting Adam Engel dispatched to the minors and Eloy Jimenez still injured, Chicago's OF consists of Garcia, Delmonico and Cordell. Plus, VanMeter called up, M. Adams and Wingenter hit IL, and Mets swap a pair of pitchers.
