How many mlb dugouts have dirt floors?

In Major League Baseball, most dugouts have concrete or turf floors, but a few teams, such as the Chicago Cubs at Wrigley Field, have traditional dirt floors in their dugouts. The number of MLB dugouts with dirt floors is quite limited, as most teams have transitioned to more modern materials for practicality and maintenance. Overall, it's safe to say that only a small minority of MLB dugouts feature dirt floors.
