I'm taking a roundabout approach on this one, editing an old thread since I am currently unable to add a new story to the site. Here is your belated post for the 2021 opening series.

The Cubs lost a battle of the bullpens in game 1, with each team's starting pitcher going only 3 innings. The Pirates bullpen essentially shut down the Cubs' offense for the remaining 6 innings and the Cubs collected only 2 hits in the game. Meanwhile, Cubs pitchers allowed 11 walks and a HBP.

12/10 UIPDATE:

NONE  

PLAYERS SELECTED BY CUBS IN AAA PHASE OF 2020 RULE 5 DRAFT : 
1. Nicholas Padilla, RHP (selected by Cubs for AAA Iowa from Tampa Bay Rays Hi-A Charlotte roster) 
2. Samuel Reyes, RHP (selected by Cubs for AAA Iowa from Pittsburgh Pirates Hi-A Bradenton roster) 

CUBS MINOR LEAGUERS SELECTED IN AAA PHASE OF 2020 RULE 5 DRAFT: 
1. Yunior Perez, RHP (selected by Detroit Tigers for AAA Toledo from Cubs AA Tennessee roster)
2. Jeffrey Passantino, RHP (selected by Pittsburgh Pirates for AAA Indianapolis from Cubs AA Tennessee roster)  

12/2 UPDATE: 

The Cubs have signed RHSP Colin Rea, LHRP Kyle Ryan, and RHRP Dan Winkler to 2021 MLB contracts (terms TBD) and tendered 2021 MLB contracts to all other unsigned players on their MLB Reserve List (40-man roster) except OF Albert Almora, OF-1B Jose Martinez, OF Kyle Schwarber, and RHRP Ryan Tepera.

So Almora, J. Martinez, Schwarber, and Tepera are now unrestricted free-agents, free to sign an MLB or minor league contract with any club (including the Cubs) without any salary restrictions.   

The Cubs MLB Reserve List now stands at 34 (six slots are open). 

+++++++++++++++++++++++++++++ 

After hurling three perfect innings in his previous start, Manuel Espinoza fired three innings of one-hit shutout ball (and threw 75% strikes), and Pablo Aliendo singled twice and drove-in a run and Cam Balego tripled and scored, in Cubs AZ Instructional League intrasquad game action Wednesday afternoon at Sloan Park in Mesa, AZ.   

The Giants at Cubs AZIL game was canceled, so the Cubs played an intrasquad game instead.   

The five pitchers who were scheduled to pitch in the AZIL game threw in the intrasquad game, and the game was called after 3-1/2 innings of play after all of the pitchers got their scheduled work. 

It wasn't possible to field two full teams because only the players who were set to play in the AZIL game played in the intrasquad game (the other position players retired to the clubhouse after early BP), so there was no DH used in the game and Alfonso Rivas (who is already an accomplished hitter and really doesn't need any more game ABs) played LF for both squads and did not take an AB (he stood out in LF for the entire game -- that's 90 minutes straight defense in 90-degree heat without a break, folks).  

Also, Ethan Hearn played 1B and Yonathan Perlaza (ex-infielder now playing outfield) temporarily moved back to the infield and played 2B. 

Fireballin' RHP Danis Correa labored through one inning of work while throwing almost all secondary stuff (only a couple of high velo FB) after throwing almost all FB in his previous outing, while RHRP Eduarniel Nunez threw almost 100% FB (only two off-speed pitches) and was sitting 95-96 (T-97). Both Corraa and E. Nunez are 21-year old Dominican power bullpen arms who could advance quickly if they can improve their secondaries and FB command (easier said than done, obviously).    

Here is the box score from the game: 

5 PM (Eastern) on the 5th day after the final game of the World Series (which was Sunday 11/1 this season) is an important deadline for several reasons. 

You already know about certain unsigned minor leaguers being declared second-contract or 6YFA on that date/time, but it is also the deadline for outrighting certain players. 

This is why you saw so many players get outrighted by MLB clubs prior to that date/time.
