SAN FRANCISCO - Austin Slater doubled with two outs in the 10th inning for his first career walkoff RBI, sending the San Francisco Giants past the Miami Marlins 6-5 on Friday in an opening-day nail-biter.
Thairo Estrada hit a tying home run to start the bottom of the ninth off Anthony Bender. Then Slater came through against Anthony Bass (0-1), scoring Darin Ruf. It marked San Francisco’s first walkoff win on opening day since beating the Padres on April 6, 1987, at Candlestick Park.
Jazz Chisholm Jr. put Miami ahead with a two-run homer with one out in the top of the ninth as the Marlins capitalized against San Francisco’s bullpen once Logan Webb left the game.
Jacob Stallings homered in the eighth and delivered an RBI single in the ninth off closer Camilo Doval to fuel Miami’s rally. Close defeats are nothing new for these Marlins: Their 29 one-run losses in 2021 matched a franchise record, also done in 1998 and 2014.
José Álvarez (1-0) recorded the final out of the 10th.
After Joey Wendle walked to begin the seventh and Webb came out, Stallings greeted Dominic Leone with a two-run drive.
Brandon Belt rode into the ballpark on a trailored boat with his signature captain hat on in a festive pregame scene, threw out the ceremonial first pitch then delivered an insurance home run in the eighth inning. It didn’t hold.
Rookie catcher Joey Bart also homered, his first in the majors, to back Webb’s latest impressive performance.
Webb allowed five hits, struck out three and walked one, leaving to a standing ovation in the seventh wrapping up his first career opening day start. Bart earned the nod behind the plate from manager Gabe Kapler. The catcher was the second overall pick in the 2018 draft.
Webb, 11-0 over 23 starts since losing last May 5 at Colorado, has emerged as the No. 1 starter for the reigning NL West champion Giants. At 25 years and 141 days, the right-hander became the youngest Giants pitcher to start opening day since Madison Bumgarner was 24 years, 242 days old in 2014.
San Francisco won a franchise-record 107 games last season to edge the rival Dodgers for the division only to lose to Los Angels in a thrilling five-game NL Division Series. They played that series without their emotional leader, Belt, after he broke his left thumb when hit by a pitch squaring to bunt Sept. 26 at Colorado.
Belt, who turns 34 on April 20, batted .274 with a career-high 29 homers and 59 RBIs then signed an $18 million, one-year contract for 2022.
Belt and shortstop Brandon Crawford each made their 11th career opening day starts, tying Robby Thompson for most in San Francisco history.
Belt and Ruf hit RBI singles in the third against Sandy Alcántara. The righty made his third career opening day start and became only the third pitcher in Marlins history to start three consecutive opening days — joining Josh Johnson (2010-2012) and Josh Beckett (2003-05).
Alcantara struck out four and walked five over five innings. He is 0-2 lifetime against the Giants over six appearances and five starts.
