Jairo Labourt

Tonight at 8:00pm ET is the deadline for teams to add players to their 40-man roster and thereby protect them from this year’s Rule 5 Draft. In other words: there will be a significant amount of 40-man roster moves made over the course of the next 13 or so hours. Six clubs already made moves to protect prospects from the Rule 5 yesterday, and each of the remaining 24 clubs should make moves today as well.

In brief: players drafted/signed at 18 years of age or younger must be added to the 40-man roster within five years of signing or be exposed to the Rule 5 Draft. Players drafted/signed at 19 or older must be added within four years. Those interested in all of the specifics can refer to articles from MLB.com’s Jonathan Mayo and J.J. Cooper of Baseball America. Perhaps of greater interest is that Mayo lists all of the prospects from MLB.com’s Top 100 list and from their organizational Top 30 lists that much be protected in advance of tonight’s deadline, while Cooper provides brief write-ups on each player that has been protected (and will continue to do so as additions are made).

Here are today’s additions to the 40-man roster. You can check out Baseball America’s coverage to learn more about the individual players listed below …

• The last team to report is the Giants, who have added a host of names to their 40-man: pitchers Ty Blach, Clayton Blackburn, Kyle Crick, Ian Gardeck, Adalberto Mejia, Steven Okert, Jake Smith, and Chris Stratton. With the roster filled up with that many pre-MLB arms, it’s fair to wonder whether the team anticipates trading from among that group.
• In their second set of 40-man promotions today, the Astros have selected the contracts of outfielder Andrew Aplin and infielder Nolan Fontana.
• Moving onto the Marlins 40-man are lefty Jarlin Garcia and a trio of righties: Jacob Esch, Austin Brice, and Nick Wittgren.
• The Cubs have placed backstop Willson Contreras, righty Pierce Johnson, third baseman Jeimer Candelario, and first baseman Dan Vogelbach onto their 40-man, the team announced.
• The Phillies added outfielder Roman Quinn and righties Jimmy Cordero and Edubray Ramos.
• Joining the Royals‘ 40-man are pitchers Matthew Strahm, Alec Mills, and Kyle Zimmer, infielder Ramon Torres, and outfielders Brett Eibner and Bubba Starling, the club announced.
• The Rockies have selected the contracts of righties Carlos Estevez and Antonio Senzatela, infielder Trevor Story, and outfielder Raimel Tapia.
• The Rays will add righties Jacob Faria, Taylor Guerrieri, and German Marquez to the 40-man roster along with infielder/outfielder Taylor Motter and rising lefty prospect Blake Snell.
• The Pirates have added top prospects Tyler Glasnow and Josh Bell to the club’s 40-man, along with fellow youngsters Harold Ramirez (an outfielder) and Max Moroff (a middle infielder).
• Righty Victor Alcantara has been placed on the Angels‘ 40-man, the club announced. As MLB.com’s Alden Gonzalez notes on Twitter, Alcantara is probably now the team’s single best prospect.
