PHOENIX – Kole Calhoun lined a two-run double in the ninth inning and the Arizona Diamondbacks rallied to beat the Houston Astros 5-4 Thursday night to win their first series of the season.

“It's bases loaded, nobody out, we need one run, there's obvious pressure there,” said Calhoun, who's from nearby Tempe and went to Arizona State. “I just tried not put too much on it, just go out and have fun in the moment, let the results just take care of themselves.”

Arizona trailed 4-3 after Alex Bregman hit a two-run homer off Stefan Crichton in the eighth inning. Junior Guerra (1-0) worked around an error in the ninth inning and the Diamondbacks loaded the bases against Ryan Pressly (0-1) in the bottom half.

Calhoun laid off a couple of pitches after falling into a hole and sent the Diamondbacks charging out of the dugout with a line drive to the corner in right. The Diamondbacks weren't sure how to celebrate while remaining socially distant, but they can work on that after finally winning a series.

“I think we're going to have to get better at that,” Diamondbacks manager Torey Lovullo said. “It's probably the most unusual feeling I've had after a walkoff win.”

Arizona starter Zac Gallen tied an NL record set by Montreal’s Steve Rogers (1973-74) by allowing three earned runs or less in his first 18 career starts. Gallen allowed two runs and six hits and struck out six in six innings.

Jose Altuve hit a solo homer off the Arizona right-hander in the fourth inning and had his first three-hit game, finishing with a double and three runs. The Astros were in good shape to win the series after Bregman's homer, but Pressly, who's been battling a blister issue, couldn't get an out.

“He hadn't had much work and he was confident to pitch and get some work,” Astros manager Dusty Baker said. “We had it all lined up, the perfect situation, but the Diamondbacks messed up our plans."
