Coming back from an injured groin is a work in progress for Milwaukee left-hander Wade Miley. He threw the ball exceptionally well during spring training before suffering the injury. Miley is pitching again, but not very successfully for Double-A Biloxi. In three innings Sunday, he gave up four runs. Miley has made a pair of starts, allowing 10 hits and six runs — including three home runs — over five-and-two-thirds innings. The Brewers will be making the decision whether to add him to the big-league roster or let him opt out of his contract soon.
