Right-hander Johnny Cueto turned down a six-year, $120 million offer from the Arizona Diamondbacks.
FOX Sports reported Cueto, 29, was offered the contract on the same day starting pitcher Jordan Zimmermann landed a five-year, $110 million deal with the Detroit Tigers.
Cueto was traded from the Cincinnati Reds to the Kansas City Royals in July.
A 20-game winner in 2014, Cueto was 11-13 with 3.44 ERA with the Reds and Royals last season.
In Kansas City, he was 4-7 with a 4.76 ERA. He threw a complete game two-hitter against the New York Mets in Game 2 of the World Series.
