SAN FRANCISCO -- The Rockies activated righty Scott Oberg and lefty Mike Dunn on Wednesday in hopes they provide more conventional, and comfortable, relief options, for manager Bud Black.
Oberg missed 15 games with a lower-back strain and Dunn missed 17 games with an upper-back strain. Both struggled, but also had solid periods before going on the disabled list.
Dunn had a nine-appearance scoreless streak before the pain he was pitching through affected his final three appearances (six earned runs in one-third of an inning).
