Giants infielder/outfielder Casey Schmitt was pulled from last night’s win over the Brewers with a knee injury. San Francisco is sending Schmitt for an MRI today, manager Tony Vitello told reporters, including Alex Pavlovic of NBC Sports Bay Area. Schmitt has been one of the brightest spots in a largely forgettable Giants season. Schmitt has spent time at all four infield positions and left field this season. Christian Koss took over for Schmitt last night and is the most likely choice to cover the hot corner until Chapman is back.
