Perhaps you caught regular Insider contributor Mike Petriello’s article on the Indians defensive struggles on FanGraphs.

It's worth a read (and a watching of the videos within the piece) and it also served as inspiration for a look at some of the season's early defensive notes.

Many people say it's dangerous to make observations from a small sample of defensive data, but I think there are some things that can be gleaned already. Here are a few thoughts.

Tulo and Arenado look like best in the business

A healthy Troy Tulowitzki could have a big impact on the left side of the infield for the Rockies in tandem with one of the the most impressive rookie defenders from 2013, Nolan Arenado.

The Rockies are converting groundballs hit to the left of the second base bag into outs at the highest rate in baseball (78 percent). Tulowitzki has six Defensive Runs Saved already. He's had as many as 31 in a season and his presence could make a big difference for Rockies pitchers. (Eric Garcia McKinley has a piece on the Rockies' infield shifting -- or rather, the lack of it.)

Yankees/Twins have it right

In terms of right sides of infields, the ones doing best at converting groundballs hit to the right of second base into outs are the Yankees and Twins, both doing so at about an 83 percent rate.

The story here is that the Yankees haven't missed a beat with the departure of Robinson Cano and temporary absence of Mark Teixeira (and perhaps the increase in shifting has something to do with it), and Joe Mauer's move to first base hasn't yet set off any alarms for the Twins.

Heyward not taking his offensive struggles into the field

Jason Heyward isn't hitting yet (we've written about that already), but he's making up for it with defense.

Most Defensive Runs Saved

Outfielders in 2014

Heyward already has 10 Defensive Runs Saved, the most among right fielders.

The Braves have the third-most outs recorded on balls hit to right and right center by our computing (76, using a pre-designed field grid), and have allowed the fewest fly ball/line drive doubles and triples (eight).

The Braves outfield defense is off to a great start this season, with a combined 19 Defensive Runs Saved.

Torii Hunter may be getting old

If you thought that Torii Hunter’s Defensive Runs Saved total from last season (he cost his team 10 runs) was a fluke, given that he'd ranked second and third in that stat the previous two years, you might reconsider.

Fewest Defensive Runs Saved

Outfielders in 2014

Hunter is already a worst-in-baseball -7 Defensive Runs Saved in right field for the Tigers.

The Tigers have the fewest outs recorded on fly balls and line drives hit to right field and right-center (38), but are tied for eighth in most doubles and fly ball/line-drive triples allowed to that same area (18).

White Sox shift their stance

What team has most shifted positions with regards to the shift? How about the Chicago White Sox, who have already shifted more times this season (84 shifts on balls in play) than they did all of 2013 (73).

Perhaps it's no coincidence that the White Sox lead the majors in "Out of Zone plays," a stat charted at FanGraphs.com that measures how often players are converting outs on balls outside of the areas in which they typically turn batted balls into outs.

Of course, given that the team's ERA is hovering around 5, we'll see how patient Robin Ventura and his pitching staff are with this new philosophy.

Is anyone worthy of a reverse shift?

Lastly, one thing I've been wondering about with the emphasis on shifting is whether any players would be worthy of a "reverse shift" -- in other words, a right-handed hitter for whom the defense tilts its infield to the right, rather than the left.

Derek Jeter took his opposite-field hitting to extremes earlier this season.

There was a hitter who was worthy of this for a bit, but he's since balanced things out a little.

Derek Jeter leads the majors in percentage of groundballs hit to the opposite field.

It's not quite as extreme now as it was in the image on the right (he's pulled five of 29 ground balls), which comes from the first two weeks of the season, but it's still notable.

Maybe Joe Maddon will have the guts to try something like a reverse shift on Jeter. Stay tuned.
