Dome of the Rock & Baseball!
Very interesting juxtaposition, Dome of the Rock and Israeli baseball, showing the appropriation of a Palestinian national and Islamic religious symbol for the promotion of an Israeli institution.
As usual, the Dome of the Rock is used as a signifier for the Jerusalem as an Israeli/Jewish city.
On a similar usage, from the 1930s see this post.
Incidentally there is no Jerusalem-based baseball team. The closest being the Bet Shemesh Blue Sox
