My thought on this Yankee team is that Boone needs to address reality. Montas is damaged goods. Sevy is back, so Montas can go to the IL and stay there. Goal for him is to get right for next year when Taillon departs in FA. He will be the 5th starter and if he needs surgery or cannot take the turn, Schmidt slots into that role. On the other points of reality, Boone needs to move Holmes to low leverage spots. His slider has lost so much RPM that it isn't a usable pitch and you cannot get by on one pitch anymore. Have him in low leverage spots and really try to harness his slider in pen sessions. Boone needs to build his bridge here. Chapman is still throwing seeds, but hitters are hitting his fastball now and he doesn't have the location to transition into a dominant weapon anymore.
So for Boone's pen, he needs to look at people who are still performing and he has plenty of options. Loaisiga has been lights out the last two months with ERA's of 1.86 and 1.00 in Aug and Sep. He isn't striking guys out like he has done in year's past but his GB rate is absolutely comical. He needs to be in the circle of trust. Trivino has been dominant since coming over. He's a sub 2ERA pitcher with significant closer history. He is in the circle of trust. Wandy Peralta has a 2.72ERA and a WHIP of 1.05. Luetge has a sub 3 ERA and has been on a roll since some early season struggles. And the breakout performer is Marinaccio who has been absolutely unhittable this year with 49K in 38IP and only 19 hits. Add in Schmidt as the long man and you've got 6 weapons to trust in the pen. If Holmes can reclaim his slider, he is the best one, but until he does, he cannot be in the circle of trust. I would only use Chap in low leverage spots and probably leave him off the roster in favor of Effross, should he recover in time from his shoulder strain.
The other thing I think everyone needs to realize is the Yankees offense has upside, but hasn't been healthy. We have seen some hints that Donaldson might be getting his mojo back. That would be welcome, if only for the next 6 weeks. Lemahieu is resuming baseball activities and could be activated soon. Rizzo returned yesterday and the offense responded. Bader returns tomorrow and will make his Yankee debut. Cabrera is starting to hit the last 3-4 games and he has the stuff to be a really good hitter. Still waiting on Stanton to go on one of his hot streaks.
Ultimately, the Yanks didn't have a fluky start, they were dominant because they put the ball in play, hit homeruns but also played small ball and pitched better than everyone. We still have a very, very solid rotation and if Sevy reclaims his stuff, a top 3 in the POs that I would put up against anyone. Cole, Cortes, Sevy is a damn good 1-3. Taillon has been good all year and German has been lights out since he was torched in his debut game this year. Add in Schmidt as the piggy backer on anyone who has a short start and the guys behind and the Yanks should be able to make some noise. I do think they have the stuff to knock out the Astros. It is just too bad they took the month of August off and let the Stros jump them
