Diamondbacks rally to defeat Giants 8-7

Posted: Updated:

PHOENIX -- Conor Jackson scored the tie-breaking run on a wild pitch with two outs in the eighth inning and the Arizona Diamondbacks completed a two-game sweep of the San Francisco Giants with an 8-7 victory Thursday night.

Mark Reynolds hit his 100th career home run and had three RBIs, and Stephen Drew drove in two runs for the Diamondbacks.

Reynolds was at-bat when Jeremy Affeldt (2-3) bounced a pitch well short of the plate, allowing the winning run to score.

Juan Uribe and John Bowker hit home runs and Aubrey Huff had two RBIs for the Giants.

Aaron Heilman (1-1) pitched 1-and-two-thirds hitless innings but allowed the tying run to reach base in the ninth when he walked pinch-hitter Matt Downs.

Chad Qualls then struck out Uribe for his seventh save in 10 attempts.

The Diamondbacks will open a three-game series against Toronto on Friday night in Phoenix.
  
Diamondbacks sign right-hander Luis Ayala to minor-league contract

The Arizona Diamondbacks have signed reliever Luis Ayala to a minor league contract in the latest of several moves aimed at improving what has been the worst bullpen in baseball.

The 32-year-old right-hander has a 29-39 career record with a 3.67 ERA in parts of six major league seasons.

He split last season with Minnesota and Florida, going 1-5 with a 5.63 ERA.

This season, Ayala was 1-3 with a 4.50 ERA in 14 games for the Los Angeles Dodgers' Triple-A team in Albuquerque before being released on May 17.

Ayala will report to Arizona's Triple-A affiliate in Reno.
