According to Peter Gammons:
Heading for Thanksgiving, the industry consensus is that the Alex Cobb showdown will come down to Cubs v. Yankees.
Alex Cobb, who will be 30-years-old next season, had a 3.66 ERA and a 113 ERA+ with a 6.4 K/9 and 2.2 BB/9 in 179.1 innings pitched last season. In his career, he has a 3.50 ERA, and a 111 ERA+. He had a 47.8 percent groundball rate in 2017 (19th in MLB among qualified starters), although he used to be more of a groundball pitcher and has a career mark of 54.0 percent.
MLBtradeRumors.com has Cobb ranked as the 11th best free agent this offseason and expects him to land a deal in the four-year and $48 million range. Seems likely to me that he’ll earn at least slightly more than that with a number of teams interested in him including the Baltimore Orioles.
Cobb would add decent depth to the Yankees rotation, but is certainly not a big name you want to see on the mound during a playoff game. This isn’t about going after the best talent on the free agent market because that would be Jake Arrieta. This is about saving money — either by getting a relatively cheaper starting pitcher, or by giving the Yankees some leverage in negotiations with CC Sabathia.
