The Brewers added another arm to the mix of candidates for the back of their rotation Wednesday night by signing veteran left-hander Wade Miley to a minor-league deal with an invitation to their spring camp, which opens Thursday. The deal, first reported by Bob Nightengale of USA Today, gives Miley, 31, a $2.5 million salary if he makes the Brewers roster with another $3.2 million incentives, which top out at 190 innings pitched or 55 relief appearances. Miley was a 16-game winner with Arizona in 2012 but had struggled in recent seasons. Pitching for Baltimore last season, he went 8-15 with a 5.61 earned run average over 32 starts, with a league-high 93 walks and 1.729 WHIP. He did strike out 142 hitters in 157 1/3 innings.
