Next, third base fungo hits to left, who throw to second, SS cuts (make a few of these the "cut off a double on a ball hit into the corner" variety - timing becomes important here, as the other fungo needs to hit many fewer balls than the fungo hitting to left). First base fungo hits to right, who come home, first baseman is cutoff, 60' from home (about pitchers mound - this postitioning puts him out of harms way should the SS overthrow second). On the throws home from right, make sure that they are the "normal" kind - hit the cutoff man, and don't hit too many. The right fielders will get to go again, as they're last throws will be the "do-or die" variety.
Maple bats in particular were once known (circa 2008) to potentially shatter in a way that resulted in many sharp edges, sometimes creating more dangerous projectiles when a bat broke. Maple bat manufacture evolved significantly, in cooperation with Major League Baseball, paying special attention to grain slope, and including an ink spot test to confirm safest wood grain orientation.
This is the drill we ran all through high school. It is the most time effective and skill intensive way to warm up a team, but your boys must be able to play catch! Fungo-ers stand in the "fungoe circles" that any good field has (and if it doesn't, you know where they're supposed to be - just outside of the home-plate dirt circle, towards the dugouts). The catch to this method is this - you have two first basemen, allowing both sides of the infield to throw across. Herein lies the only danger - one of the firstbasemen has a lengthy throw back to a shagger, so caution must be excersized (a catcher with a good head on his shoulders really helps).
Players can also create complex holes such as ‘two-part holes’ where the players must hit or reach one object before attempting to shoot at the hole. For example, a ‘two-part hole’ could consist of hitting the scoreboard first, and then once they have hit the scoreboard they must hit the ball back to home plate, that would be one hole with the player with the fewest strokes winning the hole. ‘Two-part holes’ are typically saved for the last hole in order to make things more complex and difficult on the leader.
