Retaining his rookie status in 1987, McGwire hit four home runs in the month of April, but followed in May with 15 and another nine in June. Before the All-Star break arrived, he had totaled 33 home runs and earned a spot on the [[American League]] [[1987 Major League Baseball All-Star Game|All-Star team]]. On August 11, he broke [[Al Rosen]]'s AL rookie record of 37 home runs.<ref>{{cite news|url=http://docs.newsbank.com/g/GooglePM/APAB/lib00581,122CA98E1CEF7498.html|archive-url=https://archive.today/20120708140841/http://docs.newsbank.com/g/GooglePM/APAB/lib00581,122CA98E1CEF7498.html|url-status=dead|archive-date=July 8, 2012|date=August 10, 2008|title=Baseball Today}}</ref> Three days later, McGwire broke the major-league record of 38, which [[Frank Robinson]] and [[Wally Berger]] had jointly held. In September, McGwire hit nine more home runs while posting monthly personal bests of a .351 [[batting average (baseball)|batting average]], .419 [[on-base percentage]] (OBP) and 11 [[Double (baseball)|doubles]] (2B).
