Walton will start at second base and bat ninth in Thursday's game against the Orioles, Shayna Rubin of the San Francisco Chronicle reports.
Walton will pick up his fourth consecutive start at the keystone, including his third in a row against a right-handed starting pitcher. Since being called up from Triple-A Sacramento on Friday, Walton has gone 2-for-13 with a home run and two walks, but that modest level of production looks like it'll be enough for him to be the favored option at second base over Brett Wisely, who is batting .123 since the beginning of August.
