Oakland A’s sluggers Mark McGwire and Jose Canseco, once known as the “Bash Brothers,” combined to hit 200 home runs to help their club reach three consecutive postseasons from 1988-1990.

But after McGwire went on to transcendent fame as the first man to break Roger Maris’ longstanding single-season home run record, Canseco became best known for writing Juiced, a tell-all book that helped blow the whistle on MLB’s so-called steroids era.

McGwire, one of many of Canseco’s former teammates outed in the book, admitted to taking PEDs in 2010, when he returned to the league as a hitting coach. Now serving in that role for the Los Angeles Dodgers, McGwire could not attend an anniversary celebration of Oakland’s 1989 championship team.

And though Canseco has apologized to McGwire on numerous occasions, McGwire told ESPN Los Angeles that he has no plans to make amends:

“It’s too late. I don’t care to ever speak to him again…. What he did was wrong.”

Canseco’s dedication to apologizing to McGwire seems to be matched only by his desire to call attention to himself, and he managed to combine his interests with a T-shirt he wore to a Cardinals-Dodgers game in 2012:

And after the latest rebuff, Canseco took to Twitter to show the whole world how sorry he is to Mark McGuire (sic).

Bromantic breakups aside, a home run contest between 50-year-old Canseco and 50-year-old McGwire would probably make for some reasonably entertaining TV.
