Padres GM Jed Hoyer told Dan Hayes of the North County Times that the Padres will have to acquire some innings at some point, but could do so in August (Twitter link). The Padres are looking to preserve the arms of young starters such as Mat Latos and Clayton Richard, so they're eyeing innings eaters. Jake Westbrook will likely be available next month, but it's doubtful that Livan Hernandez will clear waivers.
The Padres, who acquired Miguel Tejada earlier today, are also looking for outfielders, according to Ken Rosenthal of FOX Sports (via Twitter). They have allowed fewer runs (341) than any team in baseball, but have scored fewer runs (435) than every NL team except the Cubs, Astros, Pirates and Nationals.
