The Cubs have indeed re-signed RHP Junichi Tazawa to a new (different) 2019 minor league contract.
3/23 ORIGINAL POST
The Cubs released NRI RHRP Junichi Tazawa today, but that might not be the end of the Tazawa-Cubs connection.
Because Tazawa was a post-2018 Article XX-B MLB free-agent who signed a minor league contract more than ten days prior to MLB Opening Day (he was signed on January 26th), the CBA mandates that if the Cubs did not release Tazawa by today (five days prior to MLB Opening Day), the Cubs would have had to either add him to their MLB 40-man roster (and 25-man roster) by MLB Opening Day or else pay him a $100K retention bonus with a June 1st opt-out.
So it's possible that the Cubs will re-sign Tazawa to a new (different) minor league contract without the automatic Article XX-B retention bonus and/or the June 1st opt-out (the Cubs actually did exactly this in 2016 with Shane Victorino, Manny Parra, and Munenori Kawasaki).
Cubs Roster Moves
Although it is not yet official, the Cubs have reportedly signed veteran RHRP Junichi Tazawa to a minor league contract. Because he was a post-2018 Article XX-B MLB free-agent, the 32-year old Tazawa will get a $100,000 retention bonus if he is not released at least five days prior to 2019 MLB Opening Day and added to an MLB 40-man roster by Opening Day, and he gets an automatic opt-out if he is not added to the Cubs MLB 40-man roster by June 1st.
The Cubs have claimed 26-year old infielder Jack Reinheimer off waivers from the New York Mets, sent INF Mike Freeman and OF Terrance Gore outright to AAA Iowa (both were declared minor league free-agents at 5 PM Eastern), and reinstated RHSP Yu Darvish, RHRP Justin Hancock, RHRP Brandon Morrow, and OF Mark Zagunis from the 60-day DL.
So the Cubs MLB Reserve List (40-man roster) now stands at 39 (one slot is open).
The Cubs have claimed 26-year old LHRP Jerry Vasto off waivers from the Kansas City Royals. Vasto was acquired by KC from COL for C Drew Butera in a trade on 8/31.
The deadline for "non-waiver" (unrestricted) trades is 4 PM (Eastern) on July 31st, or 4 PM (Eastern) on Friday July 30th if July 31st falls on a Saturday. or 4 PM (Eastern) on Monday August 1st if July 31st falls on a Sunday.
The Cubs will be playing a doubleheader this coming Saturday at Cincinnati and Cubs #1 pitching prospect Adbert Alzolay is expected to be added to the Cubs MLB Active List as the "26th Man" and make his MLB debut by getting a start in one of the games.
Here is the "26th Man" rule:
