PHOENIX (AP) - The San Francisco Giants acquired right-handed reliever Matt Herges from the San Diego Padres on Sunday.

Herges was 2-2 in 40 appearances for the Padres with three saves and a 2.86 ERA.

In return, the Padres get minor league right-hander Clay Hensley, along with a player to be named or cash considerations.

Herges, 33, spent seven years in the minors before making the big leagues. He played two seasons with Los Angeles and one with Montreal before signing a minor league contract with the Padres this spring.

He began the season with Triple-A Portland. San Diego purchased his contract on April 12.

Herges has a 24-20 career record in the majors with 11 saves and a 3.43 ERA.

Hensley, 23, was the Giants' eighth-round draft pick last year out of Lamar University. He had a 6-6 record and a 3.98 ERA with Class-A clubs Hagerstown and San Jose this season. On May 3, while pitching for Hagerstown, he threw a seven-inning perfect game in the nightcap of a doubleheader against Kannapolis.

Rockies deal for Petrick

DENVER (AP) - The Colorado Rockies beefed up their bullpen Sunday by trading catcher-outfielder Ben Petrick to Detroit for right-hander Adam Bernero.

Bernero started 17 games with the Tigers with just one relief appearance, but Rockies manager Clint Hurdle said he will be used to shore up Colorado's depleted long relief corps.

Bernero was 1-12 with a 6.08 ERA with the Tigers, but received the worst run support in the majors at 2.50 runs per game. He worked at least six innings in 11 of his 17 starts.

''He's dealt with some adversity and has a history of competing and overachieving,'' Hurdle said. ''You look at the numbers of a lot of their starters and what is to say it wouldn't be different in a 'pen or a different role or on a different team.''

The Rockies have struggled in the middle innings this season, in part because of right-hander Nelson Cruz's ineffectiveness.

Cruz started the season in Colorado's rotation, but has struggled since being shifted to the bullpen. He missed 19 games after developing shoulder stiffness in April and will undergo strength tests this week to determine why his velocity has dropped.

Hurdle said Cruz, 3-5 with a 7.21 ERA, could end up with another stint on the disabled list.

Bernero has a 5-20 career record with a 5.93 ERA in 63 games in the majors. He will join the Rockies in San Francisco after the All-Star break.
