sentences:  The old schedule of 154 games (seven opponents multiplied by 22 games apiece) was replaced by 162 games (nine opponents multiplied by 18 games apiece) which led to some controversy due to the eight extra games that Maris had to try to hit 61.Ultimately, when Maris broke Ruth’s record in game 162, baseball commissioner Ford Frick instigated "The Asterisk", which designated that Maris had only accomplished the feat in a longer season, and disallowed any reference to him as the record-holder.When commissioner Fay Vincent removed "The Asterisk" in 1991, Maris was finally given credit as the single-season home run record-holder.
