The Cardinals acquired Pedro Feliz and cash from the Astros for pitcher David Carpenter, according to Astros director of social media Alyson Footer (on Twitter). Feliz, 35, has a .221/.243/.311 line this season with four homers in 304 plate appearances. He hasn't hit much in recent years, but has a reputation as a strong defender. UZR suggests that Feliz's defense has been excellent throughout his career (though he has a -7.9 rating in 530 innings so far in 2010).
The Cardinals acquired Feliz to help out at third base, since an injury to David Freese and a Felipe Lopez slump have left St. Louis thin at the hot corner. The Cardinals intensified their search for infielders this week, showing interest in multiple third basemen. Feliz makes a total of $4.5MM in 2010 (he has yet to receive about $1.1MM of that) before becoming a free agent this winter.
Carpenter, 25, was the closer for the Cards' Florida State League (High A) affiliate. He has 20 saves this year with a 2.36 ERA, 8.4 K/9 and 2.5 BB/9. The Cards drafted Carpenter in the 12th round of the 2006 draft as a catcher. Astros GM Ed Wade describes the right-hander as a "power arm" who could become a major league contributor.
