Home runs are often characterized by the number of runners on base at the time, if any. A home run hit with the bases empty is seldom called a "one-run homer", but rather a "solo" homer. With one or two runners on base, the home runs are usually called "two-run homers" or "three-run homers". The term "four-run homer" is seldom used. Instead, it is nearly always called a "grand slam".
