PHILADELPHIA -- The Phillies made one more trade before Sunday's midnight waiver Trade Deadline, shipping outfielder John Mayberry Jr. to the Blue Jays in exchange for Double-A third baseman Gustavo Pierre.
Pierre, 22, had just been promoted from Class A Dunedin to Double-A New Hampshire. He hit .263 with 23 doubles, three triples, seven home runs, 40 RBIs and a .675 OPS in 407 plate appearances with Dunedin. He has been assigned to Double-A Reading.
Mayberry hit .213 with six home runs, 21 RBIs and a .722 OPS in 138 plate appearances this season, and .242 with 52 home runs, 169 RBIs and a .733 OPS in parts of six seasons with the Phillies. The Phillies acquired him from the Rangers on Nov. 20, 2008, in exchange for outfielder Greg Golson.
The Mayberry-Golson swap was the first player transaction Ruben Amaro Jr. made as general manager.
The Phillies traded right-hander Roberto Hernandez to the Dodgers earlier this month for prospects Victor Arano, who is a right-hander, and Jesmuel Valentin, who is a second baseman.
