Clocker Grening:

MUBTAAHIJ, who finished 8th in the Kentucky Derby, just blew out a swift three furlongs in 36.02 seconds on my watch over the Belmont main track, going his final quarter in 22.83 seconds after an opening eighth in 13.19 seconds. He galloped out four furlongs in 47.88 seconds and five-eighths in 1:02.94.

While he was being asked to finish, it was far from an all-out move. He also did the with very little pre-work activity.

Along with his stablemate Umgiyo, Mubtaahij came through the paddock and jogged back to the 4 1-2-furlong pole. They quickly turned around, with Umgiyo doing a similar piece of work -- which I did not time -- before Mubtaahij did his.

This work came just three days after he breezed five furlongs in 1:01 on the turf.
