The non-waiver trading deadline is July 31, with the waiver deadline being Aug. 31.
Cueto and Leake are both in the final seasons of their contracts. Cueto is earning $10 million this season, the end of a four-year, $27 million contract. Leake is making $9.8 million in 2015 after signing a one-year deal in the off-season.
Cueto, 29, is 6–6 with a 2.73 ERA and 113 strikeouts in 118 2/3 innings this season. The 27-year old Leake is 6–5 with a 4.08 ERA and is scheduled to start on Friday against the Cleveland Indians.
While Reds management has not commented on trade rumors, there is speculation that reliever Aroldis Chapman and outfielders Jay Bruce and Marlon Byrd could also be on the move at the trading deadline.
Cincinnati is 39–47, 15 1/2 games behind the St. Louis Cardinals in the National League Central and 7 1/2 games out of a Wild Card spot.
