The Best Year at Second Base… Ever
The group of young shortstops emerging in major-league baseball has gotten a lot of deserved attention, with Xander Bogaerts, Carlos Correa, Francisco Lindor, and Corey Seager — all 23 or under — potentially ushering in a renaissance at the position. Third base gets a lot of attention, too, offering a combination both of young stars (like Nolan Arenado, Kris Bryant, and Manny Machado) and the American League’s most recent MVP (in Josh Donaldson). Historically, second basemen tend to generate less attention — perhaps because players often end up at second only when they appear unable to adequately handle shortstop or lack the size to play third. This season, however, second basemen have turned the tables and are having quite possibly the best collective season ever at that position
Second basemen have not typically been responsible for great offensive seasons as a group. Last year, Wendy Thurm looked at offense by position throughout history. Second basemen, Thurm found, have generally hovered around the low-90s when it comes to wRC+, easily below average. The graph below shows the league-average wRC+ for second basemen over the past 50 years, including this one.
Second base has rarely reached (or crossed) the 95-wRC+ threshold. This season, however, they’ve produced a 101 wRC+ on the season. We can go back further and the trend continues. In the last 100 years, the only time second basemen have recorded a collective mark above 100 wRC+ is 1924, the year Rogers Hornsby hit .424/.507/.696 and accounted for more than 5% of second-base plate appearances. With Hornsby, second basemen produced a collective 103 wRC+; without him, it would have been 96 on the season. This year’s top second baseman, Jose Altuve, has recorded an impressive 167 wRC+ is impressive, but that figure doesn’t have nearly the same impact as Hornsby’s did in the 1920s.
