He's given them innings - 145 IPs to date - which is valuable. He's ranked 6th in all of baseball, just behind Cole, Alcantara, Nola, Gallen and Webb.
From looking at his game logs, when he's on he usually goes 6 or 7 innings, giving up 1 or 2 ER. When he has a off day, he still does give them 4-5 innings maybe giving up 4-5 ERs. Really his last start where he gave up 9 ER was his only blowup this season.
13 quality starts (hate using it as a stat) but he's up there in that category, tied with Castillo, Strider, Elder, Gilbert, and ahead of guys like Ohtani and Snell lol. Pretty much he's been a durable arm for them and eating up innings for them. He's been worth the $10M contract they signed him for.
