The Pirates activated second baseman Neil Walker from the disabled list and optioned infielder Jordy Mercer to Class AAA Indianapolis, the team announced this afternoon.

Walker was placed on the disabled list after sustaining a deep cut to his right hand, an injury that occurred April 26 when St. Louis Cardinals shortstop Pete Kozma landed on his hand while turning a double play.

In nine games with the Pirates, Mercer hit .258 with three home runs and four RBIs and, from an offensive standpoint, outshined starting shortstop Clint Barmes and backup John McDonald. But Mercer has options remaining -- Barmes and McDonald do not. Manager Clint Hurdle said Sunday that would be a factor when the team activated Walker from the disabled list.
