OMAHA, Neb.  — Whit Merrifield’s RBI single with one out in the bottom of the 11th inning gave South Carolina its first baseball national championship with a 2-1 victory over UCLA in the College World Series on Tuesday night.

The Gamecocks (54-16) won six straight games after losing their CWS opener against Oklahoma. They also won the last championship played at Rosenblatt Stadium, the CWS’ home since 1950.

Scott Wingo drew a leadoff walk and took second when catcher Steve Rodriguez, perhaps distracted when Evan Marzilli squared to bunt, let an inside 1-0 pitch get past him. Wingo moved to third when Marzilli got a bunt down, and scored when Merrifield drilled a 2-0 pitch by Dan Klein (6-1) past pulled-in outfield of the Bruins (51-17).
