Sources: New York Mets acquiring Tyler Naquin, Phillip Diehl in trade with Cincinnati Reds

The New York Mets are acquiring outfielder Tyler Naquin and left-hander Phillip Diehl from the Cincinnati Reds, sources told ESPN's Jeff Passan on Thursday.

New York is sending minor league second baseman Hector Rodriguez and righty Jose Acuna to Cincinnati to complete the deal, sources said. 

The 31-year-old Naquin gives the NL East-leading Mets a veteran outfielder and left-handed bat. He has played mostly right field this season in Cincinnati but has experience in all three outfield spots. 

Naquin is hitting .246 this season, and slugged his seventh home run earlier Thursday, a solo shot in a 7-6 loss to the Miami Marlins. 

He spent his first five seasons in Cleveland before signing with Cincy as a free agent last year. He's a free agent again after this season. 

Diehl, 28, has seen limited action in the majors, including just five relief appearances and an 11.12 ERA this season. His last appearance for the Reds came May 7, and he has since been pitching for the team's minor league affiliate in Louisville, compiling a 4.24 ERA in 25 games. 

Major League Baseball's trade deadline is Tuesday.
