Biasi, 22, has only been a professional ballplayer for about a year; he was selected by the Royals in the 11th round of the 2017 draft. Though he managed ERA outputs below 2.50 at each of his first two stops throughout the minors, there was cause for skepticism based on his FIP figures (both above 4.00). Biasi hasn’t had the good fortune of out-pitching his peripherals at the A level; he’s been hit hard to the tune of a 5.08 ERA despite a 9.70 K/9 across 42 2/3 innings pitched so far on the season. Biasi’s pitched exclusively out of the bullpen, making 27 appearances.
Perrin, 25, is a towering 6’5″ righty who’s split the 2018 season between the Brew Crew’s Double-A and Triple-A levels. He’s chucked 47 1/3 innings thus far across 28 appearances (one start), and allowed 20 earned runs while notching 44 strikeouts against 20 walks. Despite that gaudy walk total, Perrin’s actually exhibited great control at previous levels of the minors. He’s never known any team other than the Brewers, who selected him in the 27th round of the 2015 draft.
Neither player is on the club’s 40-man roster, so this swap isn’t subject to the limitations beyond the July 31st non-waiver trade deadline. However, it’s not outlandish to think that the teams made this trade with major-league roster ideas in mind. Perrin, after all, has proven capable of limiting runs at the minors’ highest level, and the Kansas City bullpen isn’t exactly overflowing with high-end talent. Perhaps we’ll see Perrin get a look in the majors at some point down the stretch, though that’s obviously no certainty. For the Brewers, they’ll get something back for a player who’d have been eligible for the Rule 5 draft in the offseason to come.
