Talk:List of Major League Baseball single-inning runs batted in leaders

RBIs
While reports of statistics use RBI for the heading (American Heritage Encarta), in connected prose referring to individual runs batted in, "RBIs" seems to be the usual plural (Merriam Webster Webster's New World), as well as being in conformity with usual English plural of initialisms (MP>MPs, VIP>VIPs, HQ>HQs). jnestorius(talk) 13:49, 10 October 2009 (UTC)
