Defensively, Bour is not a stellar defender but he is not a bad defender. According to Baseball Reference, since 2016, he has -2 Defensive Runs Saved (zero is league average, which is what he was at in 2016). In 2017, that would place him eighth among 13 National League first baseman who played more than 800 innings at first, according to Fangraphs.
In UZR, again according to Fangraphs, he ranks higher as his UZR (Ultimate Zone Ranking) in 2017 was 2.2 (league average is also zero). That would place him as fifth among the 13 National League qualifiers.
While Bour’s offense is above average and his defense is around league average, his baserunning is the worst part of his game. First off, if you look at his height and weight, you might be able to deduce this as he is a big boy. According to Baseball Reference, he is listed at 6-3 and 265 pounds.
He has played in 366 games in his MLB career and he has exactly one triple and one stolen base so he is not a threat to run on the basepaths.
In addition, if you check out MLB’s Statcast data through Baseball Savant, Bour’s average sprint speed was 25.0 feet per second, which is dead in the middle of 23 ft/second, which is considered to be very poor, and 27 ft/second, which is league average. That means that he is the fourth slowest first baseman in baseball. In comparison to the Rockies, the only non-pitcher that was slower than Bour was catcher Ryan Hanigan, who’s average sprint speed was 24.6 feet per second.
