I too like pitchers duels, and this just a classic, memorable MLB game between last year's world champions trying to get back to that level and this year's very definite contenders who lead MLB in runs scored and OPS.
It was not ace vs. ace, but two pitchers who both lifted their game enough to be awfully hard to score against. Thus no whining from me about the lack of hitting by the Sox, who actually did take advantage of at least two RISP opportunities.
I do think we also saw the value of having Leon behind the plate. When he and the pitcher are in sync, and that's crucial when Porcello is on the mound, magic can happen.
JDM and Bogie both had 2 hits and an rbi apiece.
Cora's managing was letter perfect--the right lineup, the right catcher, the right decisions in the 7th and 8th to leave first Procello and then Brewer on the mound--and to bring Brasier in to close in the 9th. Let's not forget that Cora used his bullpen a lot at Baltimore and that last night was the 14th straight game for the Sox without a break.
I like ERA, but agree other stats are important. When a pitcher is on the mound, I look for 4 things--at least 3 different pitches, good command, at least two pitches that are tough to hit, and a good mix of pitches.
I frankly don't think Porcello has any single pitch that is really tough to hit, so he has to excel at the other three things to succeed the way he did last night. Last night he did throw some so-so fast balls down the middle or close to it, but usually they were in the context of a good mix and therefore caught the Twins hitters off guard. Except the guys who hammered that double to CF in I think the 7th.
