I wouldn't go so far as to say that. I think it's been a great deal for the Angels and the Padres.
Of course, we know how good Frieri is doing, but Amarista is up to 4 HR, 16 RBI and a .290 Batting Average. And Donn Roach moved up to AA with 9 IP of 0.00 ERA, after 8 games at A+ with a 1.74 ERA.
Love it when trades help both teams.
