The San Francisco Giants aren't the only team seriously interested in Chase Utley.

According to sources, several teams have made trade offers for the Philadelphia Phillies infielder.

The Los Angeles Angels, Houston Astros, Chicago Cubs, Los Angeles Dodgers and New York Yankees are also in the mix to acquire Utley, who reportedly wants some assurance of playing time before waiving his full no-trade clause.

Utley has a $15 million club option for 2016 that no longer will vest automatically based on plate appearances. His club option would then drop to $11 million, but the Phillies would be expected to take the $2 million buyout instead.
