Tyson Blach: Everything you need to know

The Cubs re-signed Blach to a minor-league contract Wednesday. Blach elected free agency earlier this week after being removed from the Cubs' 40-man roster, but he's now back in the organization on a new contract. The lefty threw three scoreless frames in his lone appearance for Chicago and will give the organization swingman depth at Triple-A Iowa.

Blach elected to become a free agent Monday. Blach had been removed from the Cubs' 40-man roster and will test out free agency rather than accept an outright assignment. The lefty could wind up re-signing on a minor-league deal, but he will have the ability to negotiate with all teams.

The Cubs designated Blach for assignment Tuesday. Blach spun three scoreless innings out of the Cubs' bullpen Monday against the Brewers in his lone appearance for the club, and his reward is being jettisoned from the 26-man and 40-man rosters. The lefty will likely clear waivers, and if that happens, he would have the ability to decline an outright assignment and become a free agent.
