Baseball Info Solutions has been tracking shifts comprehensively since 2010, and teams have shifted more and more over the last few seasons. From 2010-11, teams averaged less than one shift on a ball in play per game. In 2012, that number jumped to 1.9 shifts per team per game, and so far this season, it has increased again to 2.4 shifts per team per game.
In particular, there are a handful of teams that have shown a marked increase in team shifts on balls in play this season. Keep in mind that the 2012 column includes data for a full season while the 2013 column includes between 13 and 15 games. If these teams continue at their pace, they will fly way past their total shifts from last season. See 2013 Pace column.

The Astros, Cubs, and Red Sox have compelling narrative regarding their new shift-heavy tendencies. Both the Astros and Cubs feature newly installed front offices that are heavily emphasizing analytics. The Red Sox, meanwhile, have replaced manager Bobby Valentine with John Farrell, who shifted more often in 2012 with the Blue Jays than any team except the Rays. The reason for the increase for the Pirates and Reds are less obvious, but it may be as simple as the fact that shifts have proven to be effective. Here at Baseball Info Solutions we have been suggesting to our major league team clients that they shift more frequently since 2005, and we publicly went on record with this recommendation in The Fielding Bible—Volume II in 2008.
It is still too early to draw definitive conclusions about Shifts Runs Saved based on 2013 shift data. However, analytics from Baseball Info Solutions show that teams combined to save 75 runs last season by shifting.
