Last year he was the Sox lone selectee for baseball's "Summer Classic", the All-Star game.
In the equivalent of two 'full' campaigns with the Red Sox he has six home runs and eighty-five RBI.
In the same vein, he averages about two WAR (if you divide three seasons into two). He was 49th in WAR last season, ahead of Jackie Bradley, Jr. (2.6 to 2.2) but with over 500 plate appearances, about double Bradley's.
After the All-Star break, Holt was .265/.311/.341/.652.
He's the guy that some will say, "I wish we had eight more of" on the field. Count me out on that one, unless someone is looking for the early 1960's Boston Red Sox. Hustle alone doesn't win ball games. Talent and hustle win ball games.
Maybe the Red Sox and manager John Farrell will catch lightning in a bottle. Holt is a "bargain basement" player, barely above the MLB minimum (which of course any of us would love to make). At age 27, Holt is approaching the statistical zenith of his career. And he is a nice player. But "ambition should be made of sterner stuff."
