Jim Callis and Jonathan Mayo have been doing mock drafts for MLB Pipeline over the last two months, releasing them every Thursday, taking turns making the picks. This week belongs to Callis, and he has the Pittsburgh Pirates taking Georgia high school second baseman Termarr Johnson with the fourth overall pick.
Johnson has been mentioned for the Pirates a few times over the last four months. He has a chance to be an elite batting average/OBP guy, with double-digit home run power. His bat is extremely advanced for a high school player.
Callis notes here that the Pirates might employ the same strategy as last year, going for a top talent at a slightly discounted price, leaving them room in their draft bonus pool to go after higher upside player with later picks.
