Sleepy baseball players

Fatigued ballplayers make worse decisions as the season goes on

Drug dealers who sell greenies Vanderbilt University neurologist Scott Kutscher discovered something interesting:

To see whether baseball players suffer the effects of sleep loss as the season drags on (or skips along for six non-tedious months, depending on your inclinations), Kutscher and his colleagues looked at data from 2011 back to 2006, after the MLB cracked down on steroid use. For each team, they tracked how often players swung at pitches outside the strike zone. Over the course of the season, the researchers saw a steady increase in how many out-of-the-strike-zone pitches players swung at. These badly judged swings went up by about six-tenths of a percent each month.

There may be some other factors at play like less-experienced players filling out rosters late in the season, but Kutscher says that these results tracked what they’ve observed in other people who have suffered from fatigue and sleep-deprivation.

But I’m sure that players who took amphetamines to “pep up” before games back in the 60s and 70s didn’t experience any performance-enhancement at all.

Marlins Park has been around since 2012, but coming into Thursday’s action, the ballpark hadn’t seen any player rob a home run. Royals outfielder Jarrod Dyson changed that in Thursday night’s series finale in Miami.

Christian Yelich smoked a 1-2 slider that Edinson Volquez left up in the zone, hitting what looked like a solo home run to straightaway center field. Dyson gave chase, timed his leap, and snagged the ball in spectacular fashion to save a run on Volquez’s behalf.

The Statcast numbers are pretty impressive:

Indeed, Dyson’s snag is the first home run robbery at Marlins Park, according to ESPN Stats & Info.

The Mets are concerned with starter Jacob deGrom and are considering pushing back his next start, MLB.com’s Anthony DiComo reports. The club thinks the right-hander is fatigued.

deGrom, 28, has had another strong season, currently standing with a 2.96 ERA and a 137/32 K/BB ratio in 143 innings. However, he’s battled command issues in his last two starts. Against the Giants and Cardinals, he gave up a combined 13 earned runs on 25 hits and three walks with eight strikeouts in nine and two-thirds innings.

The Mets are already without Steven Matz, Zach Wheeler, Matt Harvey, and Jon Niese. deGrom’s recent bout is just the latest in what has been a season-long starting pitching struggle for the club. Nevertheless, only the Cubs (2.85) and Nationals (3.57) have posted a better aggregate starting pitching ERA than the Mets’ 3.66.
