I first became acquainted with Charlie Morton while covering the Pittsburgh Pirates as a newspaperman and while conducting research for my non-fiction work Big Data Baseball.

Morton was the first major-league player I encountered who exhibited a real interest in analytics. He developed an appreciation of numbers from his father, Chip, an accountant and former Penn State basketball player. As Morton struggled with inconsistency early in his major-league career — he posted a 6.15 ERA with the Braves as a rookie in 2008 — he turned to PITCHf/x information to better understand his stuff and performance beyond a traditional box score. He found PITCHf/x data and fielding-independent numbers kept him sane. He found advanced statistics and PITCHf/x provided a better baselines of performance to study. His father dove into the data, too, and they often had phone calls discussing the quality of his stuff, the velocity, and horizontal and vertical movement, etc.

Earlier in his career with the Pirates — and with the help of Jim Benedict and Ray Searage — Morton had dropped his arm slot and and adopted the two-seamer as his primary pitch. His new, and present, delivery reminded many of Roy Halladay. The Pirates had Morton watch video of Halladay. And at times, Morton’s stuff — his darting sinker and bending curveball — also resembled former Philadelphia and Toronto ace’s. In Pittsburgh, during the good times, he earned nicknames like “Electric Stuff” and “Ground Chuck.” He posted a 62.9% ground-ball rate in 2013 to go along with a 3.26 ERA and 3.60 FIP. He earned a three-year contract extension after the 2013 season.

The reigning American League champion Cleveland Indians haven’t been quite as dominant so far in 2017 as last year. Lackluster production from their outfielders has been a big culprit. Michael Brantley is seemingly healthy and productive once again, but there’s been a void beyond him. Abraham Almonte, Brandon Guyer, and Austin Jackson have been varying degrees of unremarkable in limited playing time and have all found their way to the 10-day DL. Minor-league journeyman Daniel Robertson has been playing right field this week, while Lonnie Chisenhall has started 18 games in center this season.

The Indians were desperate for outfield help, and luckily they had an impact player waiting in the wings in the form of top prospect Bradley Zimmer. Zimmer has mashed Triple-A pitching this year to the tune of .294/.371/.532 and has stolen nine bases. Zimmer is a 6-foot-5 power hitter who also happens to be a speedy center fielder, which means Chisenhall can return to a corner where he belongs. Zimmer has also posted double-digit walk rates at most levels of the minors, which gives him yet another way to provide value. Very few prospects can get on base, hit for power, and play good defense at a premium position, making Zimmer a rare bird. On the downside, however, Zimmer has some serious contact issues that threaten to eat away at his offensive value. He struck out at a high-but-acceptable 30% clip this year, but was up over 37% in his first crack at Triple-A last year, when he hit .242 without any power.

One of the more fascinating rollouts from Baseball Savant this season has been xwOBA, a metric that utilizes launch angle and exit velocity to assign a hit value (single, double, triple, home run, or out) to every batted ball and then translates the results to “expected” wOBA. Why does it matter? By stripping out the influence of luck and defense, it gets closer to something like a “deserved” hitting number.

Here’s what the glossary at MLB.com says about the metric:

xwOBA is more indicative of a player’s skill than regular wOBA, as xwOBA removes defense from the equation. Hitters, and likewise pitchers, are able to influence exit velocity and launch angle but have no control over what happens to a batted ball once it is put into play.

For instance, Tigers first baseman Miguel Cabrera produced a .399 wOBA in 2016. But based on the quality of his contact, his xwOBA was .459.

For the most part, those claims make sense. But that’s not to say xwOBA can’t be beaten. To understand how, let’s look a little bit at how wOBA compares to xwOBA. Let’s begin by looking at all players from last season who recorded at least 400 at bats and compared their wOBAs to their xwOBAs. The scatter plot looks like this.

There’s a pretty strong relationship there. Of the 183 players represented above, 150 had a disparity between wOBA and xwOBA under 30 points. That seems pretty conclusive.

So what are we to do with this data? We could look at the outliers on either end, presume that they were either unlucky or lucky when it came to batted balls, and then move on with the analysis. However, before we do that, we might want to look at other reasons for the potential disparity. To that end, I did an eye test of sorts. I took all players with at least 400 at bats in both 2015 and 2016 and looked at their xwOBA minus wOBA in both seasons. If a player had a negative number, he might be considered to have had some good luck. If the numbers were positive, he might have had some bad luck.

CLEVELAND – Miguel Sano knows what he wants.

In the visiting team quarters in Progressive Field, there’s a small kitchen — like something you might find in a World War II-era submarine — that offers players various pre- and post-game sustenance. On Sunday morning, Sano, apparently unsatisfied with the options, disappeared from the clubhouse and reappeared with rectangular aluminum carry-out pan containing mangú, a Dominican breakfast dish of mashed plantains topped with a type of thinly sliced sausage. He said he had procured it from a local restaurant. The 6-foot-4, 260-pound Sano is known as a popular teammate and this catering feat was a prime example. As he appeared with breakfast, several of his teammates, also of Dominican origin, huddled around a card table in the center of the clubhouse for a Sunday morning feast.

Sano is selective at the plate, too.

I’ve always loved Bronson Arroyo’s leg kick. There’s some whimsy in it, is maybe why. At the very least, it represents a different mechanical approach than one finds elsewhere in the league.

Turns out, there are reasons against flinging the lead leg out into space like Arroyo does — and yet, his reasons for doing it make some sort of sense, as well. And in between the two, there’s even something about the future of baseball in that kick. It’s a kick that contains multitudes.

First, let’s revel in its glory — in this case, from the hitter’s view. Is it… majestic?

CLEVELAND – Byron Buxton sat before his locker in the road clubhouse at Progressive Field before a game last week, intermittently scrolling through his smart phone and chatting with several nearby teammates. As I approached Buxton to request an interview, his clubhouse neighbor, Miguel Sano, morphed from a 6-foot-4, 260-pound third baseman to clubhouse bouncer. He was prohibiting me from addressing Buxton until I paid a fee, something of a toll. He was joking, I think, and I played along, asking if he would give me a receipt for business expenses. While Sano, who’s known for his loquaciousness and sense of humor, prompted some laughter in the corner of the Twins clubhouse, he was also perhaps trying to protect his teammates a bit from another prying journalist.

Buxton wore the label of “No. 1 Prospect in the Game” for multiple years, which has placed his offensive struggles at the major-league level under great scrutiny. But no one has placed more pressure on Buxton than himself. And that pressure was creating something that prevents success from occurring in the batter’s box: anxiety.

This is Alex Stumpf’s fourth piece as part of his May residency at FanGraphs. Stumpf covers the Pirates and also Duquesne basketball for The Point of Pittsburgh. You can find him on Twitter, as well. Read the work of previous residents here.

Andrew McCutchen is struggling early in the season. If you’ve followed him for the last three years, you’re aware that this is nothing new.

In 2015, he hit .194 in April. In 2016, he slumped his way to a .719 OPS through the first four months of the season. After getting benched for a series in Atlanta, he posted an .852 OPS over the rest of the campaign, just north of the .844 career mark he’d possessed entering the year.

Last year’s strong finish created optimism for this season. So far, however, McCutchen is slashing just .212/.218/.401, with a career worst 84 wRC+.

The absence of both Jung-Ho Kang and Starling Marte — due to visa issues and a PED suspension, respectively — means that the Pirates require an excellent performance from McCutchen just to keep the offense afloat. So far, that hasn’t happened. In fact, the results have been even worse recently: entering play Sunday, McCutchen had recorded a .132/.207/.302 line in 58 plate appearances since April 29th.

As usual, though, the results only tell part of the story. The quality of contact is sloping downward, too. In 2015, McCutchens’ exit velocity averaged out to 90.7 mph. In 2016, it was 89.6 mph. Through May 13th of this year, it was 87.6. The rate of balls hit at 95 mph or above is down, from 44.8% in 2015 to 42.6% in 2016 to 39.3% in 2017. The same goes for barrels, too, dropping from 9.5% to 8.5% to 5.6%.
