No. Sorry, but no. There's too much kool-aid going around TD on our pitching. It's a bad, bad staff. As a staff, both starters and relievers are in the bottom third in baseball.
Ryan is a back of the rotation pitcher. While he's a rookie, he's already 26 years old. He' not going to improve much more. He's made 30 ML starts so we have a decent idea of what he is over a full season - 30 starts, 160-170 innings ERA+ around 100, 2 WAR. That's not bad but it's a back-end arm but not what a playoff team wants to throw out in a make or break game. He's not top 50 in any stat right now. Ober hopes to be this good. And the rest of the pipeline looks to be more of this.
I like healthy Mahle and Gray. Both are in the 2/3 range although Gray will be 33 next year so that's a problem. But it would be silly to expect Gray to better than he was this year and Mahle is a big question mark.
Maeda is 35. His last season, he managed a 91 ERA+ and .3 WAR. He's coming back from TJ. He'll be a bullpen arm.
This season has pretty clearly shown we don't have the horses to pitch us to a 90-win season - heck, probably not even to a winning season. We need an overhaul of the system. Barring that, we need several real starters, and simply hoping that another year of experience and getting healthy is a really bad plan.
The lineup will be fine.
