Being the Pirates' second baseman is dangerous business these days.
Bobby Crosby was removed from Monday's game against the Cubs with concussion-like symptoms after colliding with outfielder Lastings Milledge.
On Friday, Neil Walker collided with Ryan Church and suffered a concussion. He has been sent back to Pittsburgh for more tests.
The Pirates released their Opening Day second baseman, Akinori Iwamura, two weeks ago. Andy LaRoche has been transitioning from third to second but is a work in progress. The only player to start at second for the Pirates this season other than Iwamura, Walker and Crosby is Delwyn Young, who has started there three times and is batting .221.
