Alex Rodriguez is ALL-IN on the idea of breaking ties in MLB games with impromptu home run derbies ... saying Tuesday, "Why not?!"
"I like it," A-Rod said on ESPN's "Get Up." "Let it fly!"
Of course, the wacky idea was first -- at least, seriously -- brought about by Dodgers star Justin Turner last week, who said he wanted sluggers to determine results of tie games.
Under JT's plan ... if teams were knotted up through 10 innings, the big bats would come out, and whoever hit the most dingers in a derby-style finish would earn the W.
