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 Tazawa 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.
