The Heat Index

Billy Koch, who signed a two-year, $10.6 million contract with the White Sox in the off-season, had a 5.30 ERA at week's end and was on the verge of losing his closer job. After Koch blew his fourth save in a loss to the Devil Rays last Friday, manager Jerry Manuel hinted that he may no longer use Koch in save situations. Time is running out for manager Bruce Bochy, whose Padres are on their way to a fifth straight losing season. And G.M, John Hart may take the fall in Texas, where the Rangers are headed for a fourth straight last-place finish.
