The best way to help a pitching staff - aside from adding better pitching - is to put behind them the best fielding shortstop, second baseman and center fielder on the roster.
Neil Walker is doing fine at second. Center fielder is a more complicated issue, given the number of outfielders on the team and the pending return of Yoenis Cespedes. However, at shortstop, the Mets have options, especially when factoring in top SS prospect Amed Rosario, who is again crushing the ball in Triple-A.
I appreciate Asdrubal Cabrera and see him as an important part of the 2017 team.
