B]Joe Maddon vs. Robin Ventura[/B]
Tampa Bay Rays manager Joe Maddon has a reputation of being one of the smartest men in baseball, and it's well-deserved. He manages to squeeze a lot of wins out of generally undermanned ballclubs, and he does that by making good use of a very deep bag of tricks.
Chicago White Sox manager Robin Ventura is a little different. He's a players' manager and a good communicator like Maddon, but he doesn't take the same kind of hands-on approach that Maddon does.
This is especially evident in the two managers' use of infield shifts. Though the exact numbers are hard to come by (I would love a heads up as to which site tracks shift numbers, percentages, etc.), John Dewan of BillJamesOnline.com published a piece in the middle of May that showed that the Rays were shifting more than any team in baseball by a wide margin.
Maddon has won the AL Manager of the Year award twice already.
Per Dewan, the Rays had shifted 171 times by May 16. They had played 38 games by then, meaning they were shifting 4.5 times per game. That sounds about right to me.
The White Sox, on the other hand, had zero shifts at that point. None.
Conventional defensive numbers suggest that there's no reason for Ventura to shift his defense. Per ESPN.com, the White Sox rank first in all of baseball in fielding percentage, and they've made fewer errors than any team in baseball. They've only allowed 14 unearned runs all season.
The Rays, meanwhile, have made 67 errors this season, second-most in baseball. Their fielding percentage is .979, also second-worst in baseball. All those shifts don't seem to be doing them much good.
Think again. The Rays have allowed 40 unearned runs this season, but they've balanced things out by only allowing 303 earned runs, 16 fewer than the White Sox have allowed.
Much of the credit for that is owed to Tampa Bay's pitching staff, which is deeper than Chicago's. But the infield shifts have made a difference, and that difference shows up in the advanced defensive stats.
According to FanGraphs, the Rays rank second in baseball with a DRS (defensive runs saved) of +40. That's a figure that more or less counterbalances the amount of unearned runs they've allowed, as it shows that the Rays have managed to save a lot of runs when they've been able to avoid booting the ball.
Robin Ventura has worked wonders for the White Sox this season, but he qualifies as a "hands off" manager.
The White Sox have a DRS of -1. They're not quite as good defensively as their fielding percentage would lead you to believe.
If that doesn't convince you that infield shifts make a difference, perhaps another set of numbers will: batting average on ground balls.
Per Baseball-Reference.com, Rays opponents are hitting .230 when they hit the ball on the ground. For the White Sox, Baseball-Reference.com tells us that opponents are hitting .239 when they hit the ball on the ground.
That's a big disparity. Too big to be a coincidence.
There are more factors in this discussion than just infield shifts, but the reality is too hard to ignore. Baseball's most shift-happy team is saving more runs than 28 other ballclubs. Baseball's least shift-happy team isn't saving any runs.
It's worth noting that the Rays have won one more game than their Pythagorean record says they should have. The White Sox, on the other hand, have won two fewer games than their Pythagorean record says they should have.
