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.

Update (6:35 PM ET): This is a three-team deal also involving the Diamondbacks, per Nick Piecoro of the Arizona Republic. The Diamondbacks will receive outfielder Steven Souza from the Rays and second baseman Brandon Drury will head to the Yankees. Lefty reliever Anthony Banda will go to the Rays, Piecoro adds. The Diamondbacks will also receive prospect Taylor Widener from the Yankees, per Joel Sherman of the New York Post. MLB.com’s Steve Gilbert adds that the Rays will get two players to be named later from the D-Backs.

Souza, 28, is earning $3.55 million in his first of three years of arbitration eligibility, so the Rays are presumably saving money in moving him. Last season, Souza hit a productive .239/.351/.459 with 30 home runs, 78 RBI, 78 runs scored, and 16 stolen bases in 617 plate appearances. Souza’s arrival almost certainly pushes Yasmany Tomas out of a starting gig.

Drury, 25, has played a handful of positions in his brief major league career. Last year, he played second base in Arizona, batting .267/.317/.447 with 13 home runs and 63 RBI in 480 PA.

Banda, 24, made his major league debut last season, posting an ugly 5.96 ERA with a 25/10 K/BB ratio in 25 2/3 innings. The peripherals suggest he pitched better than his ERA indicated.

Widener, 23, was selected by the Yankees in the 12th round of the 2016 draft. This past season with High-A Tampa, he pitched 119 1/3 innings and posted a 3.39 ERA with a 129/50 K/BB ratio. MLB Pipeline rated Widener as the 14th-best prospect in the Yankees’ system.

Robert Murray of FanRag Sports reports that the Rays will acquire second base prospect Nick Solak from the Yankees. The Yankees’ return is presently not known.

Solak, 23, was selected by the Yankees in the second round of the 2016 draft. He spent last season between High-A Tampa and Double-A Trenton, hitting a combined .297/.384/.452 with 12 home runs, 53 RBI, 72 runs scored, and 14 stolen bases.

MLB Pipeline ranked Solak as the eighth-best prospect in the Yankees’ system and the fifth-best second base prospect in baseball, praising him for his ability to hit line drives as well as his speed.
