What is another word for hot-corner?
Pronunciation: [hˈɒtkˈɔːnə] (IPA) 
Hot-corner, a baseball term that refers to the area beyond the third base and first base, is expressive yet limited in usage. A possible synonym for hot-corner, in this context, is the "infield corner." This description accurately depicts the location of the hot corner and is more inclusive of the first and third base positions, not just the third base. Alternatively, a "dangerous zone" or a "zone of pressure" may express the feeling of the hot corner from a player's point of view. While "hot spot" could be used more broadly, the phrase does have a sense of intensity that aligns with the connotation of the hot corner.
