Wada was a non-roster invitee whom the Cubs were considering for the fifth spot in the rotation. The left-hander gave up seven runs on 10 hits and five walks over 5 2/3 innings in three games, including one start.
The Cubs' spring camp roster now consists of 16 pitchers, four catchers, eight infielders and seven outfielders.
Jose Veras, Pedro Strop, James Russell, Wesley Wright and Carlos Villanueva are set for the bullpen, unless the Cubs decided to use Villanueva as the fifth starter at the beginning of the season. Other relievers still in the mix include Justin Grimm, Hector Rondon and Alberto Cabrera, who is out of options.
"I don't know if being out of options is the defining factor of somebody's thinking," Cubs manager Rick Renteria said about putting together the 25-man roster. "I think their performances dictate that."
The next roster cuts are expected after Tuesday's day-night split-squad games.
