Pirates place Grilli on bereavement list

DETROIT -- Jason Grilli, the Bucs' invaluable setup reliever, was placed on the Bereavement List Sunday morning following the death of his wife's grandfather.

Left-hander Jeff Locke was recalled from Triple-A to take Grilli's place on the roster.

Locke brings a fresh arm from Indianapolis. He was scheduled to start in the Minors Sunday, after having gone 3-3 with an ERA of 3.02 in his first eight starts of the season.

The 24-year-old Locke made his brief Major League debut last season with the Pirates, going winless in four September starts. He has made only nine lifetime relief appearances in 142 professional games.
