Washington Nationals: 5 candidates to fill final rotation spot

Alex Cobb

Since he debuted in 2011, Alex Cobb has been one of the most consistent starters in the league. He does not get the press that he deserves since he has been in the same rotation as Chris Archer and played for the Rays, but he has been one of the best pitchers in the league.

Cobb has also been extremely successful while pitching in the powerhouse that is the American League East. Pitchers are typically more successful when they move from the American League to the National League, so Cobb could be even more impressive if he joins the Nats.

Pitching is at a premium nowadays, and any significant free agent pitcher will undoubtedly receive a large contract, but Cobb could end up being affordable. Last season, he only made $4.2 million, which is an absolute bargain for a pitcher of his stature. He definitely deserves a raise and will likely get it, but could still remain affordable.

Like Arrieta, Cobb has a tie to the Nats through Martinez. Before becoming the Cubs bench coach, Martinez was the Rays bench coach and coached Cobb in the first four seasons of his career. If Cobb enjoyed playing for Martinez, there is an incentive for him to come to the Nats.

Cobb has also only made it to the postseason once, and is now on the wrong side of 30. He is not getting any younger and likely only has a couple contracts left, so he should go to a competitor if he wants a good chance to win. If he values winning and enjoyed playing for Martinez, the Nats are a perfect fit.

While Cobb is not necessarily a big name like Arrieta, he would be an excellent fit and would certainly improve the Nats.
