The Pirates acquired Morneau on August 31st in a deal which sent outfielder Alex Presley and a player to be named later (Welker) to Minnesota.
Morneau, the 2006 AL MVP, had spent more than a decade in the Twins organization prior to being dealt to the Pirates, who in the midst of a playoff race, sought added pop in their lineup. Though his power (.312 SLG) failed to shine through in his limited time with the Pirates, Morneau still hit .260 with a .370 on-base in 92 plate appearances over the course of 25 games. Including his time with the Twins, Morneau has hit .259/.323/.411 with a 103 OPS+ and 2.0 WAR this season. He is expected to enter the free agent market this winter.
Welker, who's birth name is Matthew, is a 27 year old right handed reliever who the Pirates selected in the second round of the 2007 amateur draft out of the University of Arkansas. Standing at 6-foot-7, the Washington native has pitched 7 seasons in the minors, throwing 474.1 innings (mostly in relief) with a career ERA of 4.19. He made his big league debut in June of this year, and ultimately appeared in 2 games for the Pirates this season. Of the 4 batters he faced, none reached base.
