the downside to this strategy is that unless needed to replace an injured player, an optioned player must remain in the minor leagues for 10 days. the strategy i suggested would require the brewers to option fiers and/or peralta very soon so the 11th day down could be his day to start in the rotation. what's unclear is whether or not the brewers could pull those players back over to play any of the remaining major league spring training games, or if they'd be forced to play in minor league spring training games (and thus, against lesser talent). furthermore, a rotation for nashville appears to have formed, and pitchers such as hiram burgos, johnny hellweg, tyler thornburg and ariel pena would be bumped to allow fiers and/or peralta to get their work in. if i recall correctly, brewers previously optioned have played in exhibition games at miller park in the past, so why would the rules be any different for exhibition games being played in arizona?
