OMAHA, Neb. (AP) – South Carolina opens the College World Series finals against Arizona on Sunday night trying to become the first school in 40 years to win three straight national championships. Gamecocks coach Ray Tanner hasn’t announced his starting pitcher. Sophomore right-hander Konner Wade (10-3) will start for Arizona (46-17).  Tanner says the Gamecocks (49-18) are pretty good but aren’t the 1927 Yankees. He adds that it’ takes some luck to reach the finals three years in a row.  The Gamecocks had to replace five regulars from the team that beat Florida in last year’s finals. The last school to win three titles in a row was Southern California in the 1970s.   Arizona this season is batting .330 and averaging seven runs a game.
