Sources: Cueto turns down $120 million offer from Diamondbacks

PHOENIX -- Johnny Cueto has rejected a six-year, $120 million offer from the Arizona Diamondbacks, sources confirmed to FOX Sports MLB Insider Ken Rosenthal on Monday.

Arizona wants a front-line starter and would have made the right-hander by far the highest-paid player in the organization.

The Diamondbacks met with Cueto and his representative last week, according to sources.

The 29-year-old right-hander was acquired by Kansas City in a midseason trade with Cincinnati this year. He went a combined 11-13 with 3.44 ERA.

He struggled during the regular season after the trade, going 4-7 with a 4.76 ERA but was 2-1 in the postseason. Cueto became the first American League pitcher since 1991 to throw a complete World Series game, a two-hitter against the New York Mets in Game 2, when he retired 16 of the last 17 batters he faced.

In 2013, Cueto went 20-9 with the Reds, leading the National League in strikeouts (242), starts (34) and innings pitched.

The rejection of the offer first was reported by MLB.com.
