The Brewers’ Jared Hughes is the type of pitcher who’s endangered.

When Hughes was one of the more effective relievers in baseball for the Pirates from 2013 to -15, he relied on one pitch — a sinker — that he threw time after time in the lower part of the strike zone. Over the last year-plus, however, two important trends in the game have conspired against Hughes. For starters, the strike zone shrunk for the first time in the PITCHf/x era last season, according to Jon Rogele’s research. Worse, it shrunk in one particular area, down, where Hughes likes to pitch. Jeff Sullivan found that the zone continued to contract in spring training. The other trend is that more and more hitters have gone in search of fly balls, adjusting their swing planes to become more effective at lifting pitches down in the zone.

Devised originally in response to a challenge issued by sabermetric forefather Rob Neyer, and expanded at the request of nobody, NERD scores represent an attempt to summarize in one number (and on a scale of 0-10) the likely aesthetic appeal or watchability, for the learned fan, of a player or team or game.

How are they calculated? Haphazardly, is how. An explanation of the components and formulae which produce these NERD scores is available here. All objections to the numbers here are probably justified, on account of how this entire endeavor is absurd.

Vargas (48.2 IP, 95 xFIP-) vs. Pineda (47.1 IP, 66 xFIP-)
Michael Pineda continues to possess an arm constructed of electricity or something like electricity. Consider: he’s recorded the seventh-highest fastball velocity among the league’s 94 qualified pitchers and fifth-best swinging-strike rate among that same population. What else he’s done, though, is walk hardly anyone. Does he concede home runs with surprising frequency for a pitcher who otherwise exhibits signs of good command? Yes. That’s how the world is, though. Let’s not belabor it.

In something of a surprise move, the Blue Jays summoned top prospect Anthony Alford to the big leagues on Friday. The move is a surprise not because Alford lacks talent, but because he’s played a mere 33 games above A-ball, all of which came this season with the Jays’ Double-A affiliate. Alford has performed exceptionally well this season, slashing .325/.411/.455. But he was overmatched by low-minors pitching as recently as last season, when he struck out 29% of the time and could only muster a .236/.344/.378 batting line at High-A.

Alford cut his strikeout rate by over 12 percentage points (from 29% to 17%) this year while maintaining his robust walk totals and modest power. The result has been substantially better offensive numbers. This is an encouraging development, especially since Alford’s so much more than his offense. He’s a 70 runner per Eric Longenhagen, which makes him a no-doubt center fielder and a threat on the bases.

A few years back, I was sure that throwing too many breaking balls was bad for pitchers’ arm health. I wasn’t alone — there was some decent research backing up that hypothesis. As the methods for examining the question have become more refined, however, and further work has been conducted on the matter, it looks like we’ve found that it’s not so much breaking balls as velocity that most directly affects arm health.

Perhaps teams have been on the same journey, because curveball usage — and breaking-ball usage, in general — is up to heights we haven’t seen before.

Breaking-ball usage has increased. That said, the uptick has been slow and gradual. Perhaps too slow and gradual. Maybe we should be pushing it.

Godley (18.2 IP, 72 xFIP-) vs. Richard (53.2 IP, 85 xFIP-)
If one takes for granted that the ideal outcome for a batter is a fly ball — and there are a number of hitters (Josh Donaldson, J.D. Martinez, et al) who do regard that as the ideal outcome — then one might regard Zack Godley as the pitcher most well suited to preventing that outcome. Consider: nearly 40% of plate appearances against him so far this season have ended either in a strikeout or a walk. Of the batted balls Godley has conceded, more than 70% have been grounders. “If a batter cannot elevate,” wrote Isaac Newton in lesser-known text, “then he’s incapable of consequently celebrating.” This is the principle on which Godley has based his approach.

Martin Cervenka is looking to join a select group of his countrymen. Currently the lone product of the Czech Republic in professional baseball, the 24-year-old native of Prague is hoping to follow John Stedronsky (1879), Frank Rooney (1914), and Carl Linhart (1952) as the only Czech-born players to see big-league action.

Cervenka has been climbing the ladder slowly, but surely. Signed by Cleveland when he was 16, he began playing stateside two years later — the Indians wanted him to finish high school first — and he’s currently strapping on his catcher’s gear in Lynchburg. He’s also swinging a much-improved bat. In 32 games with the high-A Hillcats, Cervenka is slashing .280/.328/.407.

Competition-wise, it’s a long way from Prague to pro ball.

“Back home, it’s a bunch of clubs playing on weekends only,” explained Cervenka, who estimated there are “five or six” baseball diamonds in Prague. “There are 10 teams in the top league, and something like 14 teams in the second league. In total, they play about 55 games a year. There are some really good players, though. We have one of the top four or five (national) teams in Europe.”

Outside of Czech baseball’s small inner circle, even the best players are largely anonymous. Despite his unique standing, Cervenka is basically John Doe. Read the rest of this entry »
