Sources - New York Yankees trading for Chicago Cubs rookie reliever Scott Effross

The New York Yankees are in agreement on a deal to acquire right-handed reliever Scott Effross from the Chicago Cubs, sources told ESPN on Monday.

Right-hander Hayden Wesneski is headed to the Cubs, sources said.

Effross, 28, is a sidearmer in the midst of a standout rookie season. In 44 innings, he has a 2.66 ERA, strikeout-to-walk ratio of more than 4-to-1 and 2.19 FIP, the 10th best in baseball among pitchers with more than 40 innings.

Trades for relievers with multiple years of team control has been a focus of teams at this deadline — and in the case of Effross, he will not reach free agency until after the 2027 season. The Yankees are betting on him retaining his effectiveness, something evaluators believe he can do in spite of a fastball that sits around 90 mph.

Effross' excellent command of his fastball and slider (with a unique changeup) has allowed him to strike out 50 batters and walk just 11. His best attribute may be his ability to keep the ball in the ballpark. Effross has allowed just two home runs this year after giving up two in a 14⅔-inning stint late last season.

A 15th-round pick out of the University of Indiana in the 2015 draft, Effross pitched parts of seven seasons in the Cubs' system before his debut last season. He was immediately effective last year, too, striking out 18 and walking just one.

Wesneski, 24, is 6-7 with a 3.51 ERA in 19 starts for Triple-A Scranton/Wilkes-Barre this season. The Yankees selected him in the sixth round of the 2019 draft out of Sam Houston State.

The trade of Effross came a day after the San Francisco Giants' acquisition of shortstop Dixon Machado, who had been in the Cubs' minor league system. Chicago is expected in the time before the Aug. 2 trade deadline at 6
