The AL participants are Blalock, Boston's David Ortiz and Baltimore's Rafael Palmeiro. New York's Jason Giambi, who has been battling an intestinal parasite, was initially scheduled to compete but withdrew from the lineup Sunday night. No replacement for the Yankees' slugger has yet been named.
Three of the four active players with 500 homers will compete: Bonds
(681), Sosa (555), Palmeiro (540). Griffey, who has 501 homers, would have been the fourth. Thome, who hit
his 400th home run last month, connected for his major
league-leading 28th of the season Thursday night.
