I think Adolis Garcia is on that list, though I'm not quite sure where. He has seemed to have lost ground. He didn't do much in his brief sample size in the majors in 2018. He slashed .118/.118/.176 in 17 at-bats. He tripped over third base at a horrible time, and that was really bad, but does that mean he's never going to get another look? Considering the competition, maybe? I'm not sure. He seems to have slipped off the radar, falling behind O'Neill, Carlson, Thomas and Arozarena. Spring training, if he's there, offers a chance to shake up that list.
Garcia's power (.505 slugging percentage at Class AAA) is intriguing, but it's been accompanied with a .260 average and a .299 on-base percentage at that level. We're talking 1,000-plus at-bats. He's 26.
O'Neill, still just 24, has a .554 SLG at Class AAA, with better average (.267) and much better on-base percentage (.339).
We're using "better" in the relative sense here.
That's why the difference between O'Neill and Garcia discussion, until Garcia proves otherwise.
