L.A. Angels Manager Mike Scioscia -- Thank God for David Freese ... We Don't SUCK at 3rd Base Anymore!

L.A. Angels manager Mike Scioscia is PUMPED -- telling TMZ Sports he's fired up about locking up former World Series MVP David Freese 'cause he'll finally stop the bleeding at 3rd base.

Scioscia was at Burbank Airport this weekend when we asked about Friday's big trade -- when the Angels got Freese from the St. Louis Cardinals in a 4-player deal.

It's a huge move for the Halos -- considering they ran through seven 3rd basemen last season ... and finished the year under .500.

"Yeah, we're real excited about it," Mike told us ... "I think [Freese is] gonna fill a big void for us so we're excited."
