Nationals second baseman Danny Espinosa has never been one of the top prospects in baseball, due to his low batting average, but he has plenty of power and decent speed to stick at second base or shortstop, and has a great glove. I remember reading an article about Espinosa that when he was back in high school, trying out for travel teams, he never believed in his skills, and always thought he was the second best shortstop on his team. One day his coach walked up to him and told him that he won the starting shortstop job over a guy who Espinosa thought was better than he, and it appears that is all he needed, as he has been a success since then.
In AA and AAA last year, Espinosa hit a combined .268-.337-.464 with 22 HRs, 69 RBIs and 25 SBs.
Last night, Espinosa went 3-5 with a HR, 3 runs and 5 RBIs. As I stated above, he will never have a very high average, but he flashes power and speed. He is currently hitting just .209-.306-.419 with 6 HRs, 27 RBIs and 3 SBs. Coming into this season, I projected a 15-15 season from him, but he is on pace 22-99 season right now. I don't expect him to drive in 100, but could see him driving in 75-80 and approach 20 HRs.
Espinosa is rosterable in NL-only and mixed leagues, as long as you can bear a bad BA from him. I expect his BA to creep up as the season goes along, and think he can make some noise on the basepaths.
