Bergen, 25, was selected by the Giants in last December’s Rule 5 Draft after spending the first four years of his professional career in the Blue Jays organization. If he clears waivers, the Giants will need to offer him back to his former employer—of course, the Blue Jays are not required to accept Bergen back into the fold, in which case the Giants could keep Bergen in their organization.
In his first taste of Major League action, Bergen has appeared in 21 games for the Giants, striking out 18 batters in 19 2/3 innings. Those numbers have in part led to a 5.55 FIP, which backs his overall 5.49 ERA. With Bergen no longer on the roster, top prospect Logan Webb looks like a good bet to stick around for an extended look, especially after an impressive debut.
Meanwhile, Avelino is slated to make his first big league appearance of 2019 after a six-game Major League stint in September of 2018. One of the fruits of the trade that sent Andrew McCutchen to the Yankees, the 24-year-old Avelino has spent the entire season in Triple-A. With a .771 season OPS, he’s regarded as the Giants’ No. 27 prospect by MLB Pipeline, which touts his arm strength from the shortstop position and his defensive versatility.
