On July 15 St louis and dodgers played?

Kershaw played trough 4 complete innings and later there was a pitching chage in the bottom of the fifth to replace kershaw once A.Graig hit a sac. fly to score Pujols. So if you add up all the runs scored that is six while Kershaw was pitching, so why does it say Kershaw gave up only 5 runs?? it should be 6 runs, right?
