MONTERREY, Mexico -- Asked before Sunday’s game about his impressions of Estadio de Beisbol Monterrey, Astros manager AJ Hinch stated the somewhat obvious when he said “it rewards hard contact, on the ground or in the air. The dimensions are normal, but the ball flies a little bit.”

That became apparent soon after the first pitch was thrown in Sunday's Mexico Series finale between the Astros and Angels. Both teams sent multiple balls into the stands, or, at the very least, to the last inches of the warning track in the deepest parts of the outfield.

Alex Bregman further proved Hinch’s theory in the fifth inning with the most impactful of all of Houston’s hard-hit balls: a grand slam, the third of his career, which gave the Astros a three-run lead and ultimately a 10-4 win over the Halos.

“My swing felt good for the first time all year,” Bregman said. “And it also put us in the lead, which is the most important thing. It was so much fun here. We had a blast.”

“Blast,” was, of course, the key word. The Astros teed off against the Angels during this two-game Mexico Series sweep, piling on double-digit run totals in both games and outscoring their division foe by 18 runs (24-6).

Bregman drove in eight of those 24 runs and was 5-for-10 with three big flies for the series.

“He’s going to hit the ball hard and he loves the moment,” Hinch said. “He loves the pressure that comes with the big moment. I think it’s impressive to watch him flip the pressure on the pitcher. Even though most of the time the pitcher has the advantage on what pitch he’s going to throw, where he can throw it, there’s very few places in the strike zone where you can throw [to] Bregman with runners in scoring position.”

How much did the ball fly in Monterrey’s warm, humid and elevated conditions? Twelve of the 14 runs scored Sunday came via a home run.

“I think [the balls] flew better the first day,” Bregman said. “Today, the balls that were hit high were getting caught up in the wind and staying in the ballpark. Just a really fun place to play.”

Because the Mexico Series was played at a non-Major League stadium, the game had to be absorbed by the general public in a more old-school fashion. No Statcast, and therefore, no data on how hard the hitters were hitting the ball or how far the ball traveled after it left the bat.

So we’ll have to revert to a more traditional way of describing Bregman’s second slam of the season: it went a long, long way.

Significant defensive lapses by the Angels earlier in the fifth inning helped pave a path to Bregman’s game-changing moment. Robinson Chirinos reached with one out after he was plunked by Halos starter Matt Harvey, who then yielded a base hit to George Springer after an Aledmys Diaz flyout. The runners advanced on a Jonathan Lucroy passed ball, and after a Jose Altuve walk, Angels manager Brad Ausmus replaced Harvey with right-hander Cam Bedrosian.

On paper, the move made sense -- Bregman had one hit in 11 at-bats with three strikeouts vs. Bedrosian prior to this showdown. But things move quickly in real time, and after Bedrosian fell behind Bregman 2-0, he served up a fastball that Bregman deposited on the grassy batter’s eye in center, beyond the 400-foot sign in straightaway center.

Houston hit eight home runs over the two games.

“We put up really good at-bats,” Hinch said. “I think one after another, it got a little contagious. Our guys did a good job of hitting the ball hard, and getting in good hitter’s counts and doing a lot of damage. We clearly played well here in Monterrey.”
