Rock Fall Readies for Vosburgh

‘TDN Rising Star’ Rockfall (Speightstown), winner of the GII True North H. and GI Vanderbilt H., worked a half-mile in :49.21 Saturday at Belmont in preparation for a start in the GI Vosburgh H. Sept. 26. “He worked really well, he seems to be maintaining form,” trainer Todd Pletcher said. “He’s on target. He’s been remarkably consistent and it’s been a lot of fun to see him develop into a top-class sprinter.”
