SAN FRANCISCO -- - The Arizona Diamondbacks set a major league record with their 23rd straight road loss, making dubious history in getting trounced by the San Francisco Giants 10-3 Thursday.

The dejected D-backs trudged off the field and quietly made their way back to Oracle Park's visiting clubhouse following the final out of their latest loss, breaking a tie with the 1963 Mets and '43 Philadelphia Athletics for road futility in the modern era (since 1900).

Held to just a lone single, hit by pitcher Zac Gallen, through six innings, Arizona fell behind 6-0. Diamondbacks players periodically glanced at the center-field scoreboard throughout this blowout, helpless to stop this runaway train of despair that began nearly two months ago.

The MLB mark felt almost inevitable after Tuesday's collapse, which saw Arizona blow a 7-0 lead in an anguishing 9-8 loss to the Giants. Manager Torey Lovullo's team has lost 14 in a row overall and 28 of its last 30, falling to 20-50 for the worst record in the majors.

The Diamondbacks' only consolation coming off this four-game sweep: They don't play again on the road until June 25 at San Diego, exactly two months to the day since their last road victory. Then again, Arizona isn't scheduled for a road game against a sub-.500 team until July 27 at Texas.

Arizona's last road win came April 25 at Atlanta, when Madison Bumgarner pitched a seven-inning no-hitter to complete a doubleheader sweep. At that point, the Diamondbacks were a solid 9-8 away from Chase Field, with no signs of the trouble ahead.

Since then, the Diamondbacks have been swept on the road by the Marlins, Mets, Dodgers, Rockies, Brewers, Athletics and Giants.

Arizona has been outscored 137-60 in those road losses. Last week, Lovullo fired hitting coach Darnell Coles and assistant hitting coach Eric Hinske.

The 1963 Mets and '43 Athletics, incidentally, were both guided by Hall of Fame managers toward the end of their tenures. Casey Stengel turned 73 on the day the Mets ended their slide, while Connie Mack was 80 while Philadelphia skidded.

Gallen (1-2) allowed four earned runs in 2⅔ innings in his first start back from a sprained pitching elbow. The right-hander also recorded Arizona's first hit of the afternoon, a third-inning single off Giants starter Kevin Gausman.

Gausman (8-1) limited the D-backs to two runs on four hits in eight masterful innings. The right-hander struck out six and walked one.

Curt Casali homered and drove in four runs for San Francisco, finishing a double shy of the cycle. Steven Duggar went 3 for 3 with an RBI double and Mauricio Dubon and Mike Yastrzemski drove in two runs each as the Giants improved the best record in the majors to 44-25.
