Sun Burnes: Arizona Signs Ace Righty Corbin Burnes to Anchor Rotation

Last offseason, the Diamondbacks were in search of a marquee starter to pair with Zac Gallen atop their rotation. The market was thin at the top – Yoshinobu Yamamoto and Shohei Ohtani were probably never available to them, so their best options were Sonny Gray, Blake Snell, Eduardo Rodriguez, Shota Imanaga, and Jordan Montgomery. They signed two of those guys, and neither delivered the rotation-stabilizing performance they had expected. But instead of waving their hands in the air and raving at the injustice of variance, the Diamondbacks got right back on the horse:

Corbin Burnes was the best free agent pitcher available. In each of the last five seasons, he’s been one of the top pitchers in the game, racking up a 2.88 ERA, 3.01 FIP, and 816 innings pitched. He’s second in WAR (21.7) over that time frame, second in RA9-WAR (23.2), second in strikeouts (946), and third in innings pitched. In other words, he’s been a capital-A Ace, a set-it-and-forget-it choice at the top of the starting rotation. He’ll receive $35 million a year for six seasons, with an opt-out after the second year of the deal, which also includes a $10 million signing bonus.
With Gallen also on their dance card, the Diamondbacks have one of the best one-two combinations in the majors. That doesn’t even include Merrill Kelly, a borderline All-Star when healthy, or Brandon Pfaadt, who looked like he was finally breaking out before a rough final two months of the season. Add in Montgomery and Rodriguez, and Arizona goes six deep with plausible playoff starters. That’s how you injury-proof a rotation – sheer depth.
