Worth noting

• Jose Contreras (lower back) resumed throwing on flat ground on Friday, and is scheduled to return to the mound for a bullpen session on Monday.

• The Bucs hit four homers for all of their scoring in a 5-2 victory at Milwaukee on May 25 -- matching their total number of long balls in a dozen games around that occasion. They entered Sunday's game with two homers -- both by Neil Walker -- in their last six games. Pedro Alvarez proceeded to connect for a solo homer in the second inning of Sunday's game.

If you think that is odd, consider this: The Pirates owned a Major League-long streak of 48 straight games with at least one extra-base hit through Wednesday -- and did not have one in the three games since before Alvarez's shot.
