The necessity of "calling" for a fly hit applies with particular force to the centre fielder.

Jackson also got some help from rookie centre fielder Ramon Laureano, who made an outstanding defensive play in the third inning.

The centre fielder must back up second base on all throws from the catcher, and also on throws from any other position, whenever possible.

The centre fielder should also back up the left and right fielders on all hits along the ground which either-of them runs in to meet.

He should assist the right and centre fielders in the return of long hits, running well out into the field to receive the out-fielder's throw.
