For MLB defenders, making three errors in an inning was nearly unheard of over the past half-dozen years.

This season, however, there has been a curious spike in such occurrences.

From 2013-18, the only player to be charged with three errors in one inning was Jean Segura, then with the Mariners, against the Yankees in 2017. Less than two full weeks into the 2019 season, there have been three individual three-error innings already -- two of them by Seattle players. Is it a statistical oddity? Or the start of a new "trend"?

Here’s a look at all three of this season’s individual three-error innings.

Kevin Newman, SS, Pirates
April 8 vs. Cubs

Newman had a rough bottom of the second inning vs. the Cubs, starting when he made a throwing error with two outs and no runners on base to extend the frame. The Cubs went on to score six runs, the sixth coming when Newman juggled Kyle Schwarber’s grounder up the middle and then made an errant throw to first.

Tim Beckham, SS, Mariners
April 5 vs. White Sox

Beckham’s defensive woes began immediately in this game, as his fielding error allowed leadoff hitter Leury Garcia to reach in the bottom of the first inning. Garcia later came around to score when Beckham misplayed Jose Abreu’s grounder on a potential double play and subsequently threw the ball wide to first baseman Jay Bruce. Before Newman broke up the streak, the last three MLB players to record a three-error inning were Mariners.

Dylan Moore, 3B, Mariners
March 30 vs. Red Sox

After no player had a three-error inning in 2018, Moore made a trio of miscues on three straight plays in the ninth inning of Seattle’s fifth game of the year. With the Mariners one out away from a win, Moore bobbled Mookie Betts’ grounder and sailed a throw over the head of first baseman Ryon Healy, allowing Christian Vazquez to score. Boston scored another run when Moore was unable to field Rafael Devers’ sharp grounder, cutting Seattle’s lead to 6-4. Moore then bobbled J.D. Martinez’s ground ball and fired a low throw to first for another error and another Red Sox run. However, Nick Rumbelow caught Xander Bogaerts’ looking to pick up his teammate and end the game.
