Castro went 1-for-2 with a solo home run, two walks and a second run scored in Tuesday's 8-7 loss to the Padres.
Castro was initially scheduled for a day off, but he ended up starting at third base when Kyle Karros (biceps) got scratched. This was Castro's second game in a row with a homer, and he's up to 11 long balls on the year, including five in July. He's hitting .259 with a .738 OPS, 45 RBI, seven stolen bases, 47 runs scored and 15 doubles over 92 contests in a utility role.
