NFHS 5-1-1f5/OBR 5.12 (MLB Umpire Manual)
If a batted ball becomes stuck in a fielder’s glove and the fielder is unable to get it out, the ball is dead and the batter and/or all runners get two bases.
[An MLB interpretation says the ball remains in play and the fielders can throw the glove/ball combination in an attempt to get an out.]
