No. 5 San Francisco Giants Loss: SP Jonathan Loaisiga

2019 Stats: 4 G, 3 GS, 1-1, 4.50 ERA, 1.50 WHIP, 13 K, 14.0 IP, .255 BAA
2019 WAR: 0.2

The New York Yankees famously released Jose Quintana before he went on to find significant success with the Chicago White Sox, who in turn flipped him to the Chicago Cubs for Eloy Jimenez and Dylan Cease.

There’s a chance that Jonathan Loaisiga can provide some redemption with the Yankees on the other side of things this time around.

The Giants signed Loaisiga out of Nicaragua on Sept. 13, 2012. After a solid debut, he missed the next two seasons with shoulder issues, and hew as eventually released on May 28, 2015.

The Yankees scooped him up the following February, and in 2017 he put himself on the prospect radar by posting a 1.38 ERA, 0.61 WHIP and 33 strikeouts in 32.2 innings.

He continued to climb the ranks last season and made his MLB debut on June 15 with five strong innings against the Tampa Bay Rays in a win.

The 24-year-old ranks as the No. 2 prospect in the Yankees system and the No. 59 prospect in baseball, according to MLB.com, who wrote that he “has the upside of a No. 2 or 3 starter if he can stay healthy” in his prospect bio.

While he has yet to fully deliver on his potential, the upside is obvious, and giving him away for nothing makes it hurt a little more.
