Complete profile and scouting report of the newest Twins' pitcher LHP Adalberto Mejia

The Twins acquired LHP Adalberto Mejia, from the San Fransisco Giants, in exchange for Eduardo Núñez.   Núñez came to the Twins from the Yankees for Miguel Sulbaran who came to the Twins from the Dodgers for Drew Butura who came from the Mets for Louis Castillo who came from the Marlins for RHPs Scott Tyler the Twins 2001 2nd round draft pick and Travis Bowyer the Twins 1999 20th round draft pick.

Mejia was signed as international free agent from the Dominican Republic by the Giants in 2011.  Mejia last played for the Giants in AAA Sacramento River Cats (Pacific Coast League,) and was invited to their 2016 MLB camp for his first time.  He is on the Twins' 40-man roster, and likely September callup.

Mejia was born on 6/20/1993 in Bonao, Dominican Republic and was a late bloomer signing by the Giants as an eighteen year old.  That season in the Dominican Summer League he impressed, starting 13 games for 76 innings with 71 K (8.4 K/9) and only 8 BB, with a 0.868 WHIP, 1.42 ERA and 1.75 FIP.  This was enough for him to skip the Giants' US-based Rookie leagues, jumping right on full season A in 2012, playing for the Augusta GreenJackets of the Southern Atlantic League. He participated in 30 games, among them 14 starts. His final numbers for that season were:  106.7 IP  with 79 K (6.7 K/9) 21 BB (1.8 BB/9), with a 1.341 WHIP, 3.97 ERA and 3.29 FIP.  He started the season in the pen, with limited success and moved into the rotation in June, where he found success, finishing the season with a 6-3 record, 3.00 ERA and 1.13 WHIP, post All Star break.

The next season he moved up to the San Jose Giants of the High A California League.  He started 16 games (87 IP) with 89 K (9.2 K/9) and 23 BB (2.4 BB/9) for a 3.31 ERA,  4.20 FIP and 1.126 WHIP.  He miss 48 games that season in May and June with shoulder issues, but came back okay.  He was called to AAA Fresno to start a single game (5 IP, 5 H, 2 HR, 2 ER, 2 BB, 2 K) and participated in the Arizona Fall League playing in 7 games, 3 as a starter for 8.47 ERA, 1.529 WHIP, 7.4 K/9 and 4.2 BB/9 in 17 innings.  In 2014 he moved up to AA Richmond Flying Squirrels (Eastern League) where he started 21 games and relieved in one, pitching 108 innings with 82 K (6.8 K/9) and 31 BB (2.6 BB/9), for a 1.389 WHIP, 4.67 ERA and 3.78 FIP. He went to the DL three times for 6 days with a leg bruise after a ball hit him in April and for 8- and 12-days in July with finger blisters.   His weight that season went up to 240 lbs (he is 6'3") and needed to be reduced.  Unfortunately he took a banned weight loss supplement that contained stimulants and tested positive, receiving a 50 day suspension, very much like current Twins' DH/1B Kennys Vargas.

He repeated AA in 2015 after he served his suspension. He appeared in 12 games (9 GS), pitching 51.3 innings with 38 K (6.7 K/9) and 18 BB (3.2 BB/9), for a 1.091 WHIP, 2.45 ERA and 3.41 FIP.  Despite the nice performance, he needed innings so he returned to the AFL (7 GS, 31 IP , 1.258 WHIP, 3.48 ERA, 7.5 K/9, 4.1 K/BB) and also appeared in the Dominican Winter League (playing for the Gigantes, coinsidentally: 5 GS, 18.3 IP , 1.091 WHIP, 3.44 ERA, 7.9 K/9, 1.5 K/BB).  After he was invited to his first MLB spring training as part of the Giants' 40-man roster, he was caught in the numbers games and started against at AA Richmond where he excelled after he trimmed down this season (11 GS, 65 IP , 0.985 WHIP, 1.94 ERA, 8.0 K/9, 2.2 K/BB) forcing his promotion to AAA in his age 23 season (he was 22 at the time.)  His numbers (7 GS, 40.7 IP , 1.303 WHIP, 4.20 ERA, 9.5 K/9, 2.4 K/BB) are fairly impressive, especially for the Pacific Coast League.

He has an above average to borderline plus fastball that has increased in velocity this season, sitting at 92-94 and touching 95 as a starter.  Average to above average command and improving and the pitch is projecting to be plus pitch in the near future.  Natural cutting action on the pitch.  His slider is his best pitch.  Siting at 83-84 mph and up to 86.  Nice biting motion, great command and above average control.  This is a pitch that he throws anywhere on the count, pretty much like current Twins' starter Tyler Duffey does with his curve ball.   He also throws a changeup that is an average to above average pitch that can improve.  Nice fluid mechanics.

Weight is a consideration for him, and it currently is under control, listed at 195 lbs.  His ceiling is that of a number 3 starter, but he has a high floor. His floor is of a 8th inning reliever.  He held lefties to a .216/.273/.275 slash line and had 11.3 K/9 against them, which is pretty impressive for the PCL.

Mejia was listed as the 5th best Giants' prospect by Baseball America and 7th best by MLB.com.  He would be among the top 10 in my Twins' list if I had to do this list now, but likely he will be called up in September and that will disqualify him.  Very good return for the Twins.
