PHOENIX (AP) — Christian Walker crushed a 459-foot solo homer and added an RBI double, Zac Gallen threw seven quality innings and the Arizona Diamondbacks beat the Miami Marlins 5-2 on Monday night.

Walker got the scoring started in the fourth with a double into the left-center gap off Miami starter Braxton Garrett, scoring Emmanuel Rivera. Arizona's cleanup hitter followed that up with a majestic homer off in the sixth that landed in the second deck to push the D-backs ahead 2-1.

Walker's blast came off his bat at 114.1 mph, which is the hardest hit ball at Chase Field this season. It was his ninth homer of the season after he hit a career-high 36 homers in 2022.

Arizona scored two more times in the sixth on RBI singles from Gabriel Moreno and Ketel Marte to take a 4-1 lead. Moreno had a three-hit night, including a double.

That was more than enough for Gallen (5-1), who cruised through Miami's order, giving up just one run on five hits while striking out seven.

The Marlins were coming off a 5-4 win over the Cubs on Sunday that lasted 14 innings and taxed the team's bullpen. It was the longest game in the big leagues this season.

Garrett (1-2) pitched well until getting roughed up in the sixth. The lefty threw 5 1/3 innings, giving up four runs on six hits while striking out six.

The Diamondbacks finished with 13 hits and improved to 20-15 this season. They've won four of their last five.

The Marlins have lost six of their past seven and fell to 17-19.

SEGURA GETS TOSSED

Marlins third baseman Jean Segura was ejected in the sixth inning after taking a called third strike. It was his third strikeout of the game in three at-bats.

The pitch Segura was angry about was a fastball that appeared slightly low and inside, but home plate umpire Mark Ripperger thought it nicked the corner. Segura's angrily threw his helmet and bat to the ground and yelled as Ripperger responded with the quick ejection.

GOING STREAKING

Gallen had his 24 1/3-inning home scoreless streak snapped in the fifth when Miami's Jesús Sánchez doubled home Nick Fortes. The streak spanned four starts at Chase Field.

CITIZEN GURRIEL

D-backs outfielder Lourdes Gurriel Jr. was not in the starting lineup on Monday because he was a late arriving to the ballpark.

The 29-year-old had a good excuse, though. He was becoming a U.S. citizen.

“It's a pretty amazing accomplishment for him,” D-backs manager Torey Lovullo said. "Certainly proud of him. We excused him from all the pregame activity to take care of that today."

Gurriel entered the game as a pinch-hitter in the sixth and walked.

Gurriel was born in Cuba, but defected to the U.S. with his older brother Yuli in 2016. Both players have had successful MLB careers since their arrival in the states.

UP NEXT

D-backs rookie RHP Brandon Pfaadt (0-0, 13.50 ERA) makes his second big-league start on Tuesday night. The Marlins will counter with LHP Jesus Luzardo (2-2, 3.66 ERA).
