This can’t be a Barry good idea.

In his comeback from a one-year suspension for involvement in the Biogenesis drug scandal, Alex Rodriguez has been working out with Barry Bonds, according to a published report.

The San Francisco Chronicle reported on its web site that Bonds, the disgraced all-time home-run king, recently worked with Rodriguez on his swing at a facility in San Rafael, Calif.

Rodriguez posted on Instagram two photos of him swinging a bat, with the words: “Starting the year in the cage.”

According to the report, the facility is owned and run by Charles Scott, a former teammate of Bonds’ at Arizona State. Bonds, who retired with a record 762 career homers, remains an outcast in baseball because of his ties to performance-enhancing drugs.

Bonds reportedly also mentored Michael Morse, Pablo Sandoval, Brandon Crawford and other members of the Giants last spring at the facility.

Rodriguez, who turns 40 in July, has more than a year of rust from the suspension to conquer: He is coming off significant hip surgery that cost him most of 2013.

Recently, he has taken grounders at third base, but the Yankees expect any production they receive from Rodriguez to come as the DH.
