In the gymnasiums of beijing and shanghai , there were grounder competitions .
上海、北京都有健身房里玩地滚球的比赛。
Wang ping : around the early 14th century , grounder began to prevail among the common .
王平:大约14世纪初德国民间就开始流行地滚球了。
The pitcher picked up the soft grounder and could easily have thrown the ball to the first baseman . Shaya would have been out and that would have ended the game .
投手接起这个轻柔的地滚球，本来他可以轻而易举地把它传给一垒手，这样沙亚就会出局，比赛也就会结束。
