The only significant difference was in extra-base hits. While Greenberg had one more double (14) than Cabrera at the same point, he also had seven triples to Cabrera's one.
The amazing part of Greenberg's season is that he kept up that same pace over the rest of the year. The Major League season was 154 games during those days, so the 51-game mark was just about one-third into the season. Multiply Greenberg's 59 RBIs by three, and the pace would've been for around 177-180 RBIs.
No Major League player has driven in as many runs in a season since Greenberg, who finished one off of Lou Gehrig's American League record set in 1931. Hank Wilson's 191 RBIs with the 1930 Cubs have lasted more than 80 years as the big league standard.
