Despite the addition of Jorge Lopez, more help is needed in the Washington Nationals bullpen. While there are some interesting young guys, the bullpen has a dangerously low floor. GM Mike Rizzo needs to add a veteran who can provide stability after non-tendering Kyle Finnegan.
The two best candidates remaining on the market are David Robertson and Kenley Jansen. While both are old, with Robertson turning 40 in April and Jansen being 37, they still have plenty of gas in the tank. They also have long track records of closing games, something the Nats do not have on the roster.
