"They are going good, so I hope we don't slow [Round Rock] down," Moreland said.
The Rangers acquired Hamilton from the Angels on April 27, but he was still recovering from offseason surgery on his right shoulder. Hamilton has not played in any kind of regular game since the playoffs last season, and he was 1-for-13 in three extended spring games.
The Rangers haven't said how long they want Hamilton to remain in Round Rock, but his length of stay won't necessarily be dictated by performance.
"More than anything, it is about him being in shape and getting his legs under him," Rangers manager Jeff Banister said.
