Catcher.

Yesterday was mostly about Yu Darvish, who was crazy great, scattering five Houston hits in seven scoreless and walkless innings, punching out eight — every one of them swinging.

On a day when Texas seemingly had men all over the bases every inning, the Astros managed to get two runners to second and one to third over Darvish’s seven frames.

It was also about Ian Desmond coming up big in the 11th, driving in the decisive run in what would be his first two-hit game in a week and a half.

There was Jurickson Profar, delivering two hits of his own after sitting three straight days, the first driving in two big runs in the eighth and the second setting up an insurance run in the 11th.

Which was driven in by Rougned Odor, on his third hit of the day.

Which Matt Bush made stand up with his huge relief effort, facing nine Astros in the two extra innings, starting every one of them off with a strike, and earning the win after none of them crossed the plate.

Big credit to all those guys, and to Delino DeShields, whose effort in the eighth inning — six-pitch leadoff walk, jog to second on Choo hit-by-pitch, steal of third on 2-1 count to Desmond, tremendous work on the 4-2-5 rundown that allowed Choo to take third and Desmond to get all the way to second — set up the massive Profar knock, even if very little of it shows up in the box score.

With all that, another Dang Series Won. Which effectively gives Texas home field over Houston in the unlikely instance that it’s needed in October.

Speaking of things that don’t show up in the box score, though, one of the big takeaways for me Sunday — and the Saturday and Thursday and Wednesday and Tuesday before it — was Jonathan Lucroy’s impact on the game.

Never mind the single and run-scoring double, which improved his Rangers slash line to .300/.333/.800 in 21 trips.

What fires me up is the blocking and the framing and the throwing and the athleticism — and the plain conviction with which he calls a game and connects with and leads his pitcher, and the confidence he gives his staff to bury a pitch even with a runner 90 feet away — and let me just say this:

Though they are wildly different players in wholly different situations and jumped out to tremendously different starts as Rangers, the way I feel about Jonathan Lucroy’s arrival is not a whole lot different from the way I felt when Cliff Lee showed up.

I’d very much like to know whether the Astros (who, like the Rangers and unlike the Indians, were not on Lucroy’s partial no-trade list) called Milwaukee to make a legitimate effort to trade for Lucroy a week ago.

And if so, what they offered.

And if not, why not.

With no disrespect intended toward the guys who have competed behind the plate and helped Texas get to two World Series and play 162+ five times in the last six years, I haven’t been able to write this in a very long time:

Having a great catcher — and I mean an established, versatile, athletic beast of a catcher who’s in command of every phase not only of his game but also that of some of his teammates as well — is a damned baseball pleasure.
