First appearance in MLB
Posey 235 OPS, good following season after 47 more games in AAA (so why call him up the year before???)
Zunino 620 OPS, not good until 26 years old
Grandal 863 OPS as second half call up at age 23 (would be 2nd half of next year for Teel which seems fine with me)
Castro 573 OPS as second half call up at age 23
Wieters 753 OPS as early season call up at age 23, never really reached the heights expected of him especially first few seasons
None of the guys you listed were really ready their age 22 season, which you want to push Teel to appear this year. Have him appear 2nd half of next year? Sure? That seems like a more realistic timetable considering the above datapoints. He also doesn't have the prospect ceiling of some of the players mentioned above (Wieters, Posey).
