CHICAGO (AP) -- The Chicago Cubs have agreed to a $4 million, one-year contract with Japanese left-hander Tsuyoshi Wada.
Wada signed a minor league deal with Chicago last December and made his major league debut in July. He was 4-4 with a 3.25 ERA in 13 starts with the Cubs.
Wada played nine years in the Japan Pacific League before signing an $8.15 million, two-year contract with Baltimore before the 2012 season. He developed elbow soreness that spring and had elbow-ligament reconstruction surgery after a tear was discovered.
Wada is eligible for $2 million in bonuses under his new deal, which was announced Monday. The incentives are based on total starts and time on the active roster.
