The trouble started, as it is wont to do when J.A. Happ is on the mound, with a walk.

Next thing Happ knew, the bases were loaded and one out, with the Milwaukee Brewers' No. 3 and No. 4 hitters coming to the plate. A crowd of 15,173 at Minute Maid Park braced itself for the third-inning carnage to come.

Happ created an alternate universe, improvising a series of plot twists Thursday night that led to a 4-0 victory and a sweep of a two-game series.

He turned into Happ-dini, pulling off escape after escape in a six-inning outing. The Brewers got a man to third base with one out in the third, fifth and sixth innings with nothing but aggravation to show for it. What Happ showed in retiring reigning Most Valuable Player Ryan Braun and cleanup hitter Aramis Ramirez to escape that that third-inning jam, Astros catcher Chris Snyder said, was the "same thing he showed all game – aggressiveness."
