As the Washington Nationals search for bullpen depth, they brought in Joe Nathan to bolster their efforts. What role the veteran has is up for debate, but both sides hope it is with the big club.
As Nathan battles back at 42 from his second Tommy John surgery, he is working on adding a changeup to his deep arsenal. If successful, it would give him four full pitches to battle hitters.
As a closer with the Minnesota Twins, Nathan featured a 94-mph fastball mixed with a sharp slider. An occasional curve and change found their way in, but 90 percent of his pitches, according to FanGraphs were the fastball/slider combo.
