  1. Joan Gregorio P

Signed out of the Dominican Republic in 2010 by the Giants, Gregorio is one of the tallest members of the Giants organization, standing at 6-foot-7.

Gregorio is one of the more mysterious prospects in the organization in my opinion. He has primarily been a starter, but briefly spent some time as a reliever in 2015, before becoming a starter again in 2016, and he  is currently the eighth ranked prospect in the organization.

In 2010, Gregorio went 6-3 with a 2.80 ERA in 14 games started for the Giants Dominican Summer League team.

The following year he found success once again in the Arizona Fall League — going 3-0 with a 2.32 ERA in 12 games.

In 2012 the results were much different for Gregorio in short season Class-A Salem-Keizer. He went 7-7 with a 5.54 ERA in 16 starts, and he had a WHIP of 1.41, while opponents hit .272 off of him.

Gregorio improved some in 2013, going 6-3 with a 4.00 ERA in 13 starts for Low Class-A Augusta. He struck out 84 batters in 69.2 innings and had a WHIP of 1.18 — a vast improvement from the previous year.

Gregorio’s roller coast of a career continued in 2014. He started the year in High Class-A San Jose, but struggled significantly.

In five starts he had an ERA of 6.75, opponents hit .303 off of him and he had a WHIP of 1.76.

He was then demoted to Augusta, where he was able to work on his mechanics and find success, despite sporting a 2-7 record. Gregorio had an ERA of 3.57 and held opponents to a .204 average, while accumulating a WHIP of 1.13.

Things got interesting for Gregorio in 2015. He pitched the entire year for Double-A Richmond, but was mostly used as a reliever. In 37 games he made 9 starts and posted a 3-2 record with a 3.09 ERA in 78.2 innings pitched.

Then, in 2016 Gregorio was once again used as a starting pitcher. He began the year in Richmond, making five starts, before being promoted to Triple-A Sacramento.

Gregorio proceeded to go 6-8 with a 5.28 ERA and opponents hit .267 off of him in Sacramento. On the bright side, he struck out 122 batters in 107.1 innings pitched.

It will be interesting to see what Gregorio will bring to the table in 2017. He only pitched 2.2 innings in spring training this year — posting a 3.38 ERA in 2.2 innings with a WHIP of 2.25.

Although he struggled in Triple-A last year, the Giants are still high on him as a prospect and will give him a chance to hone his skills this upcoming season.
