noun
hit that advances the runner(s)

彼は進塁打を打ってランナーを二塁に進めた。
He hit a ball that advanced the runner to second base.
タイムリーヒット (timely hit) specifically drives in a run. 進塁打 only requires that a runner advances, not necessarily scoring.
Compound of 進塁 (shinrui, 'advancing to the next base') + 打 (da, 'hit'). A straightforward baseball term.
