What It Means:

Arrieta is arbitration-eligible this year, but the Cubs may opt to forego that for a long-term deal. Arrieta will be entering his age-30 season in 2016.

Arrieta has certainly earned some extra dough. He finished 2015 with a 2.61 xFIP, besting his 2.73 mark from last year. He cut his walks to 1.89 per nine innings while increasing his ground-ball rate to 56.2 percent. Arrieta won't be cheap to extend, but that doesn't mean he wouldn't be worth it.
