Robertson was in a bases-loaded jam in the fourth inning,
similar to the one he faced in the fifth inning of his first start
against Colorado on April 3.
"He's not a kid who panics,'' Astros manager Jimy Williams said. "He has very good mound presence. Certainly, I think (catcher Gregg) Zaun helped him.''
Robertson (1-1) allowed just two hits while striking out eight and walking three. He retired the last 11 batters he faced.
"I was feeling pretty good until I got myself in that little jam,'' Robertson said. "Zaunie called some good pitches and I stepped off the mound to get a little extra focus.''
Zaun is Robertson's regular catcher.
"I love working with him,'' Robertson said. "He kind of has that fiery attitude. I like that.''
Zaun thinks he and Robertson have a lot in common.
"We're both a little out there,'' he said. "He's a real
competitor. I didn't really say a lot to him tonight because when
he was in trouble, he was still aggressive.
"The difference between tonight and the last time is he was
amped up a little more then.''
The Reds were impressed with Robertson.
"He pitched a good game,'' manager Bob Boone said. "He kept us
off balance, but we chased an awful lot of bad pitches.''
Danny Graves (0-1) allowed four runs -- three earned -- and seven hits in 5 2/3 innings.
"You're going to go through those spurts when the other pitcher
dominates,'' Graves said. "Tonight, the other pitcher just gave up
two hits and there's just nothing you can do when the other pitcher
is on like that. You just have to try to scratch out a few hits and
sometimes you're going to get some runs and sometimes you're not.''
Biggio led off the game with a homer off Graves, breaking the NL
mark for leadoff homers set by Bobby Bonds. Rickey Henderson holds
the major league record with 80 leadoff home runs.
Zaun added an RBI single in the fifth for Houston.
Wagner allowed an RBI single by Austin Kearns in the ninth.
