Cleveland (Bauer) at Minnesota (Duffey) | 19:10 ET
Los Angeles NL (McCarthy) at Arizona (Bradley) | 20:10 ET
These two games receive the same precise score — to the 100th of a point — per the author’s haphazardly constructed algorithm. In the case both of Cleveland and Los Angeles, one finds talented clubs which feature greater than a 50% chance of qualifying for the divisional series. In the case of Minnesota and Arizona, one finds… not that. But then does find, on the other hand, at least a small collection of promising youth. Consider: the Diamondbacks feature the lowest average batters age (weighted by plate appearances) in the majors; the Twins, the fourth-lowest. Jake Lamb (3.2 WAR), Jean Segura (2.0 WAR), Robbie Grossman (1.2 WAR), Miguel Sano (1.0 WAR) are all in the midst of their age-26 season or something less than that, and all have recorded at least a win this year. Observing those two clubs, one is observes the future of baseball. But not literally. And maybe not even that figuratively. Not all of these brief entries are literary gold.

Luis Valbuena has a 157 wRC+ since the beginning of June playing third base for the Houston Astros. Super-prospect Alex Bregman is beating down the door with his performance at Triple-A. Perfect fits be damned. Try and tell a contending club it’s got too many good players. They’ll find some room.

MLB.com’s Jesse Sanchez just broke some news:

Source: INF Yulieski Gurriel agrees to 5-year, $47.5 million deal with #Astros #Cuba More on https://t.co/mkcBseoZWQ pic.twitter.com/6uj12AgGGL

Let’s get brought up to speed. Gurriel (previously spelled Gourriel) is 32, and he’s been considered Cuba’s best baseball player for about a decade. He’s primarily played third base, and also kicked around at shortstop and, more recently, second base. In 15 years between Cuba and Japan, Gurriel hit .335/.417/.580 with 250 homers and 121 steals. In early February, Yulieski and his younger brother Lourdes Jr., 22, defected from the island. In June, Yulieski was declared a free agent, able to sign with any club free of international spending limits. He’d been linked to the Dodgers, of course. The Mets had shown some interest. The Angels seemed to make some sense. Now, he’s an Astro.

BaseballAmerica’s Ben Badler worked up a scouting report on Gurriel last April in which he called him a plus defender at third with quick reactions, athleticism, a 70-grade arm, and the occasional mental lapse. He’s a complete hitter who bats from the right side, able to hit for average and draw a walk, and scouts see good bat speed that should translate to plus power in the majors. At the time, Badler drew comps to Hanley Ramirez and David Wright, which don’t sound so great anymore, but remember this was before the beginning of the 2015 season; Ramirez was coming off a 135 wRC+ at third base with the Dodgers, Wright was still Wright. Brian Cartwright does good work translating international player’s stat lines to MLB equivalents, and he projected Gurriel for a .283/.330/.458 line back in February, good for a .340 wOBA. There’s no expectation that Gurriel won’t hit.

Five years for a 32-year-old is perhaps a bit scary, and it’s a little more than what Dave Cameron estimated he might get last month, but Gurriel makes the Astros better now. Or, more accurately, in three weeks or so, which is when FOXSports’ Ken Rosenthal reports he’ll be ready to join the club. The Astros plan to keep Gurriel at third base, which creates an interesting positional logjam in Houston.

Most Highly Rated Game
Boston at New York AL | 19:05 ET
Wright (114.0 IP, 103 xFIP-) vs. Pineda (95.1 IP, 77 xFIP-)
Steven Wright and Michael Pineda are the same and also different. Like, for example, they possess probably 95% or 98% or whatever of the same genetic material. Because humans possess mostly the same genetic material. So, basically the same. But also, one of them’s a giant person from the Dominican, while the other is a more traditionally sized person from Torrance. So, rather different.

Here’s another manner in which they’re the same: they’ve both produced ERA numbers so far this season that’re wildly different than what their fielding-independent marks would otherwise suggest. But here’s also how they’re different: while Wright has very much outperformed his xFIP, Pineda has underperformed it.

Regard, by way of illustration, this table, which features the top-five qualified pitchers by absolute difference between xFIP- and ERA-:

It’s very likely that the appearnce of both pitchers here is more than a product of randomness. Wright, a knuckleballer, is almost certain to outperform his fielding-independent numbers. And as for Pineda, the opposite has been a trend, as well. Enough of a trend that one ought to regard it as a reflection of his “true talent”? Sure. Not to this degree. But sure.

This, in conclusion, has represented an attempt to identify a narrative where none was readily apparent.

Of all the statistical advances made in the recent past, exit velocity seems to get the most attention. Broadcasts that still shy away from discussions of WAR or wRC+ or UZR are readily using exit velocity on batted balls. Part of that could be the novelty of it, and part of it is just a fascination with how hard and how far a ball is capable of being hit. Part of it could also be a sort of familiarity. Home-run distance has long been included in broadcasts, as has been a pitcher’s velocity. Exit velocity is an easy expansion of those numbers.

That said, exit velocity isn’t just a novelty. Despite issues with the data and the importance of launch angle and batted-ball data as a means to providing context, a player’s average exit velocity can tell us a decent bit of information about a player. With another half of data available (thanks to our own Jeff Zimmerman for his assistance gathering data), we can attempt to determine whether exit velocity from last season carried over to this season.

When I looked over the winter, the correlation on an individual player level between wOBA and exit velocity was relatively strong (r=.61) over the course of 2015 for players who had played a majority of that year. That number is not as strong so far this year (r=.50), but we are also dealing with a larger (237) universe of players with a lower level (200) of plate appearances over the first half of this season. It will be interesting to see if the correlation climbs a little higher as the season continues.

Last year, there was a solid relationship between first-half and second-half exit velocity. To determine how much of last year’s numbers carried over to this season, I compared the 116 players who recorded at least 200 plate appearances in each of the last three half-seasons. First-half exit velocity from 2015 correlated well with first-half exit velocity for 2016 (r^2=.52), but not as well as second half of 2015 with first half of 2016 (r^2=.57). The strongest relationship between the periods was between the entire 2015 season and the first half of 2016 (r^2=.62).

If you want the best bet for what a player will do this year, looking at a full year of data is the way to go based on the information we have, but we don’t know if that is uniform for all players. What about the players who experienced changes from the first half of 2015 to the second half of 2015? Did those changes carry over? Yes and no.

• For the 33 players who had large increases in the second half last year (at least 1.5 mph increase), the second-half exit velocity had a slightly higher correlation than 2015 total (r^2=.51 compared to .47). A good second half of exit velocity might be a harbinger of continued higher numbers.
• For the 23 players who produced a decrease of at least 0.5 mph, the decrease seemed to have less bearing, as there was a smaller correlation (r^2=.38) for the second half of 2015 to the first half of 2016 compared to 2015 as a whole to the first half of 2016 (r^2=.44). A dropoff in the second half in terms of exit velocity is less important than the full year of numbers, it would seem.
• For the players who had relatively consistent halves in 2015, those numbers have carried forward to 2016 (r^2=.74).

When I looked at the numbers over the winter, I was hoping to find some sort of application for the data I found. Everything else is fun to figure out (depending on your definition of fun), but to find something with utility would be most interesting. I looked at the population of players last season whose wOBA seemed to underperform or overperform their exit velocity — i.e., players who’d recorded above-average exit velocity but below-average numbers, and vice versa. I found that those players who underperformed their exit velocity in the first half saw their offensive numbers rise in the second half. Similarly, players whose offensive numbers seemed to overperform their exit velocity tended to have weaker number in the second half. Taking a look at those players for the first half of the season is probably worth a post on its own, so we’ll hold off on that for now.

Know this — Dave Dombrowski likes to make trades. He was first named a general manager back on July 5, 1988, assuming the title of “youngest GM in the game” back before it was cool with the Montreal Expos. He made his first trade on July 13. His aggressive nature was sometimes just off center stage, as the teams he had previously helmed — the Expos, Marlins and Tigers — have rarely been media darlings. But now he is running the Red Sox, and they get plenty of coverage. While that level of coverage might not be fair or warranted, his deals are being scrutinized hard these days. Is he gutting the farm system? Or does Dombrowski know how to pick ’em? I thought I’d take an objective stab at his trade record.

It’s no secret that, over the last few years, the number of Tommy John surgeries has increased across all levels of baseball. As we emerge from the All-Star break, let’s take a snapshot of the current state of Tommy John surgeries at the professional ranks.

New Tommy John Surgeries
Let’s start with some good news. The number of Tommy John surgeries at the major-league level is down in 2016 compared with the last couple of seasons. Comparing totals at this point in the season over recent years, there have been fewer Tommy John surgeries to date this year than any since 2011.

In the past five seasons, I’ve attempted to track Tommy John surgeries at the minor-league level more closely than in prior years. This information is much more difficult to collect, and certainly there will be many surgeries missing from the list every season. Looking only at surgeries known to have been performed by this time in the year, however, the 2016 campaign looks more like 2012-2013 than the last two years where surgery counts had spiked.

So the most interesting question here is: has something actually changed to cause the number of Tommy John surgeries to drop this year compared with the last two seasons?

I can’t say that I know the answer, but I suspect it’s due to a number of factors.

Ben and Sam talk to BP’s Ben Carsley about the Drew Pomeranz trade, David Price and David Ortiz, the Bogaerts/Betts debate, and the impact of Theo Epstein and Ben Cherington on Boston’s 2016 team.

There’s a maddening midseason tradition of realizing April performances have subconsciously impacted our perceptions of players in foolish ways. No matter how many times we tell ourselves that the baseball season is long and small sample sizes are fickle tricksters, we inevitably look up in July to find out that a player written off for dead in April is actually doing quite well, thank you very much. It’s an unavoidable reality that first impressions matter and affect the way we view those around us. The perils of first impressions may have had no bigger victim this season than Ken Giles.

When a team gives up five players to acquire you (and a rookie-ball lottery-ticket-type prospect), expectations are inescapably large. Of course, this is the situation Giles found himself in when the Astros dealt a package of players highlighted by Vincent Velasquez and former #1 overall pick Mark Appel to Philadelphia in order to acquire the flame-throwing relief pitcher. The reason for the steep price Houston paid is that Giles was under team control for another five seasons. Intellectually, the first month of his Astros tenure shouldn’t matter any more or less than the ensuing five years but, realistically, it was inevitable that he’d be under a microscope for that first month.

Every spring, hopeful starters talk of new pitches with a gleam in their eyes. This changeup will change everything, they think. Then it comes to competitive games, and they don’t want to get beat on their fourth-best pitch, and everything goes back to where it was.

Detroit rookie Michael Fulmer had a similar story. He was flashing a plus changeup in bullpens, but not throwing it much in games. Then something changed, but he’s not sure what. From Anthony Fenech at the Detroit Free Press:

Michael Fulmer doesn’t know what happened.

He threw about 30 change-ups in one of his bullpen sessions before his start against the Rays on May 21 and something clicked.

Now, his catchers keep calling for that change-up.

“Sometimes, I’m shaking away from the change-up and they’re giving it to me again,” Fulmer said. “So, I’m like, ‘OK, I’ll throw it right here,’ and it usually works out, so by them calling it more, it’s giving me more options.”

I published a ranking last week at ESPN of the best pitches thrown by starters. Fulmer’s change doesn’t appear among the top ten. But it does appear 11th overall — and, for him, it’s impressive to see his third pitch turn up as one of the league’s best among starters (judged by z-scores for grounders and whiffs with a double weighting on whiffs).
