Diamondbacks general manager Mike Hazen confirmed Monday that Robinson wasn't included on the club's 60-man roster pool, Nick Piecoro of The Arizona Republic reports. The 19-year-old Robinson is the organization's top prospect, but since he hasn't played above the Low-A level, his exclusion from the player pool doesn't come as a major surprise. As Piecoro notes, because Robinson wasn't able to travel back to his home country (The Bahamas) when MLB shut down its season in mid-March, he's allowed to continue working out at the Diamondbacks' spring training facility when the season resumes in late July. While the likelihood that he won't play in any minor-league games is a less-than-ideal outcome for Robinson, taking part in regular workouts under the Diamondbacks' supervision should help keep his development relatively on track.
Robinson slashed .217/.294/.435 over 25 games for Low-A Kane County in 2019. Robinson earned a late-season promotion from short-season Hillsboro to Kane Country and experienced predictable struggles for a then 18-year-old in the Midwest League; however, he maintained his power numbers. Nine of his 20 hits went for extra bases, and he posted a .217 ISO after a .239 ISO at Hillsboro. Robinson's HR/FB rates were over 20 percent at both levels. He possesses a blend of power and speed, which should continue to place him atop various Diamondbacks prospect lists, unless the propensity to strike out gets out of control.
Robinson was promoted to Low-A Kane County on Saturday. This should be a nice test for Robinson, who destroyed Northwest League pitching to the tune of a .319/.407/.558 slash line with nine home runs (.239 ISO) and 14 steals in 44 games. Very few prospects can match his combination of mammoth raw power and plus speed.
Robinson is opening the year in extended spring training, Mike Rosenbaum of MLB.com reports. Obviously it would be nice to see the Bahamian sensation open the year at Low-A, but developing a 6-foot-3 teenage power hitter is a slow process, so we will need to wait for the short-season leagues to open in mid-June before Robinson makes his 2019 debut. He will likely head to the Northwest League.
