Best Farm System flags fly forever. Just ask the Royals.
1) St. Louis Cardinals (ranked #5 last year): Strengths: Everything. They have pitching, hitting, high upside, and depth. They have a proven track record of player development. Weaknesses: none really. They could use a shortstop with a better bat but so could most teams.
2) Seattle Mariners (#4 last year): Strength: Good balance between hitting and pitching, strength up the middle with Zunino, Miller, Franklin; potential ace arms; good knack for finding underappreciated college hitters. Weaknesses: Persistent problems with Latin American prospects showing poor strike zone judgment and contact issues.
3) Tampa Bay Rays (#7): System was already strong and trade with Royals just adds more. Strength: considerable pitching depth; good mix of players who will be ready now/soon (Myers, Archer, Odorizzi) plus guys at lower levels with high upside. Weaknesses: upper level hitting other than Myers….
30) Detroit Tigers (23): Very thin in all respects. Strengths: Nick Castellanos and Avisail Garcia could help soon, and there are some potential role players behind them. Bullpen arms. Weaknesses: lack of depth almost everywhere, particularly hitting.
