Early this season, one of the Nationals’ most glaring weakness was their defense. One part of the Nationals’ shakiness was the major league worst seven errors committed by shortstop Ian Desmond within the 18 games of the season. At the time, Desmond and Manager Davey Johnson expressed confidence that mistakes would calm down. “He may go 60 games without making an error,” Johnson said then. Well, it has been 32 games so far. Desmond hasn’t committed an error since he made his seventh on April 21. He has played steady and even flashy defense, including at least two plays on Sunday against the Phillies in which he displayed his strong arm and wide fielding range. He has looked like he did in his breakout 2012 season, when he played tremendous defense, committed only 15 errors all season and was a finalist for the Gold Glove award. As a whole, the Nationals defense seems to be slowly steadying. For much of the season, the Nationals led the majors in errors by a noticeable margin. They still do with 39 errors — but other teams are catching up as the Nationals slow down. They’re tied with the Chicago Cubs with 39 errors.
