EXTRA BASES: Alberto Callaspo started at third, but Manager Don Mattingly said Justin Turner is the team's primary player at the position. Asked why, Mattingly replied, "Just kind of the whole package — defensively, offensively." Turner started the Dodgers' two previous games at third base. Alex Guerrero, who has 10 home runs, made his last start at third on May 24. Guerrero, 28, was a career-long shortstop in Cuba. He played primarily at second base in the minors last season. This season, he has started nine games at third base and 21 in left field. Mattingly made reference to how Guerrero faces the challenge of learning new positions at the major league level. Mattingly also said he likes having Guerrero off the bench. Guerrero has eight RBIs as a pinch hitter, the most in the major leagues.
