John Sterling's Home Run Call For Alfonso Soriano

Did anyone notice the home run call that John Sterling had for Alfonso Soriano? It may be the worst one that he ever had actually.... "Sori, RIGHT number?" Maybe it's just me but I don't get it. I get that "Sori" is supposed to signify "sorry" but still, I don't get it and I don't think I want to get it. Sterling is slipping with the home run names but that is probably because he is out practice.
