He went 0-for-4 with three strikes outs on Friday.
Showalter said he hopes Lough doesn't try to do too much during the series — and doesn't think he will.
"It's not some vindictive what-have-you. I don't think he has got to show them anything," Showalter said. "They called him to the big leagues and brought him through their system. He knows they like him. If we don't like him, I'll guarantee you they'll take him back."
Valencia has played sparingly for the Royals, going 3-for-11 with one homer in four games this season. But Showalter said he thinks both players could thrive in their new homes.
"We liked Danny Valencia, too. They both can impact a team," Showalter said. "So I think that's definitely going to be a trade I hope works out for both teams."
