That didn't happen, but it kept Gallardo from suffering another loss to St. Louis. He came in 1-10 in 15 starts.
Cardinals starter Adam Wainwright gave up Segura's two-run home run in the first, but nothing more until three runs in the sixth ended his start and put the Brewers ahead 5-4.
Gomez hit a one-out solo home run. Martin Maldonado singled, advanced on Alex Gonzalez' single and both scored on pinch-hitter Jonathan Lucroy's double. After Wainwright hit Aoki for the second time in the game, Kelly took over and got Segura to hit into a double play.
Wainwright went 5 1-3, allowed 11 hits, the most since he gave up 11 on Opening Day at Arizona, and struck out five.
His first three pitches of the game hurt, especially the one that snapped his streak of not allowing a home run this season.
On a 1-0 pitch, Aoki' singled. Then first-pitch swinging Segura hit his fourth home run of the season.
Jay's three-run homer in the second erased Milwaukee's 2-0 lead.
Craig singled and advanced on David Freese' hit up the middle which Gallardo deflected just enough to cause shortstop Segura to backtrack and then throw late to second for the force. Jay crushed a 2-0 pitch for his third of the season.
Gallardo said the play could have gone another way.
"If I catch it, it's an easy double play, or, if I just get out of the way, Segura is right behind me. Obviously, it doesn't help falling behind the next guy and then leave a pitch out over the zone to hit it for a home run."
After Jay's home run, Gallardo retired 13 of the next 14 batter, but then gave up Craig' homer into the Cardinals' bullpen in right-center field.
