Alonso (back) is in Wednesday's lineup hitting fifth against the Giants, Padres' radio announcer Bob Scanlan reports. He had been out of the lineup for a couple days with a back issue but the rest appears to have helped and Alonso will slot into the middle of the Padres' order Wednesday. The 28-year-old first baseman is off to one of the best starts of his career, slashing .33/.415/.432 through 94 plate appearances.
