SAN FRANCISCO — Ketel Marte is roughly three inches shorter and 40-something pounds lighter compared to Andres Galarraga during his playing days. On a chilly Tuesday night at Oracle Park, Marte’s moonshot to Big Cat territory was the defining image of the Giants’ 7-5 loss to the Arizona Diamondbacks.

San Francisco, which matches its season-low of 11 games under .500, has dropped five straight games against Arizona, the first time the team has ever lost its first five games against the Diamondbacks to begin the year.

The loss wasn’t for a lack of firepower on the Giants’ end as Casey Schmitt, Eric Haase and Willy Adames all homered, the fifth time this year that San Francisco has hit three homers in a single game. Schmitt’s homer was his 12th of the season, matching the season-high he set last season before the calendar flipped to June.

Rookie outfielder Victor Bericoto recorded the first hit of his major league career, pulling a grounder into left field in the bottom of the fifth. Bericoto was a standout during spring training and won the Barney Nugent Award, hitting .419 with three homers and 14 RBIs.

Marte has absolutely tormented the Giants over the last week-and-change. Over these first five games, Marte has gone 11-for-22 against San Francisco’s pitching staff with three homers, one being of the walk-off variety.

Right-hander Tyler Mahle surrendered a homer and allowed three runs over five innings with three walks to three strikeouts.

Through 11 starts, Mahle’s 6.04 ERA is the worst mark in the majors among all qualified starters. With Logan Webb set to return from the injured list on Friday, the Giants will soon have to decide whether they keep Mahle in the rotation.
