Mike Strong, a 10th round pick in 2011, isn't a household name when it comes to Brewers prospects, but he's looked excellent since a poor first professional season in '11. He's made just one appearance above A-ball in his career, but there's always a chance a team takes a lefty with good numbers in the Rule 5 draft. He made 31 appearances in 2014 with a 2.35 ERA and 9.5 K/9. In four minor league seasons, he's struck out 297 batters in 271 innings. Strong is already 26, so between his age and his placement on the 40-man, the Brewers may look at promoting him more aggressively this season.
