DENVER -- Cody Asche is in Triple-A, preparing to become the Phillies' everyday left fielder. Domonic Brown's bat is heating up, too.

Both will rejoin the Phillies at some point, possibly soon.

Their inevitable arrivals seem to leave Ben Revere as the odd man out in the Phillies' outfield, with Odubel Herrera in center field, which is why, sources told MLB.com, the Phillies and Angels have been talking about a trade in recent weeks. The Angels have been scouting Revere for some time and like him, but the Phillies and Angels have not agreed on compensation.

It is safe to say the Phillies are seeking Minor Leaguers in return.

There is no timetable on Asche's return. He has played only eight games so far in left field. The Phillies optioned Brown to Triple-A in April, despite his $2.5 million salary. He is hitting .272 (34-for-125) with five doubles, one triple and 16 RBIs in 30 games, although he is hitting .462 (12-for-26) in his last six games.

Revere is making $4.1 million this season, and he will not become a free agent until after the 2017 season, which could make him more attractive to teams.
