March 26 (UPI) — The New York Yankees still have “a lot to prove” after their MLB season-opening shutout of the San Francisco Giants, manager Aaron Boone said.

Boone made the comments in his postgame news conference after the 7-0 triumph Wednesday at Oracle Park in San Francisco. The Yankees outhit the Giants 10-3. Reigning American League MVP Aaron Judge was the only Yankees player who failed to collect a hit.

“We’ve got a lot to prove, and look, we’re confident,” Boone told reporters. “I know they’re confident in their ability to have good at-bats and put up runs. We’re one game into this thing and we’ve still got a long ways to go to prove that. I think we have a chance to do that.”

Boone called ace Max Fried “effectively wild.” The left-handed pitcher allowed the first three Giants he faced to reach base. He then settled in, allowing just one more hit and tossing four strikeouts over the next six innings.

“To give us 6 1/3 after the way the first inning started was big,” Boone said of Fried. “That’s what an ace looks like when he’s grinding. What a tone he set for us.”

Shortstop Jose Caballero brought in the first run of the MLB season with an RBI single in the second. Third baseman Ryan McMahon roped another single off Giants ace Logan Webb in the next at-bat, bringing in two more runs for the Yankees.

Center fielder Trent Grisham ripped a two-run triple to right field for a 5-0 lead two at-bats later. The Yankees plated the final two runs of the night in the fifth inning off an RBI single from designated hitter Giancarlo Stanton and a throwing error from Giants shortstop Willy Adames.

Yankees relief pitchers Jake Bird, Brent Headrick and Camilo Doval combined to allow just one hit, with two strikeouts and a walk, over the final 2 2/3 innings.

Stanton and Yankees catcher Austin Wells recorded two hits apiece. Wells, who also drew a walk, was the only player to reach base three times. McMahon and first baseman Ben Rice also reached base multiple times in the victory.

Judge went 0 for 5 with four strikeouts. All-Star second baseman Luis Arraez was the only Giants player to reach base more than once. He went 1 for 3 with a walk.

Webb surrendered nine hits and seven runs, including six earned, with seven strikeouts and a walk over five innings.

The Giants (0-1) will host the Yankees (1-0) in the second game of the series at 4:35 p.m. EDT Friday in San Francisco. Left-handed Robbie Ray is slated to start for the Giants. The Yankees are expected to start right-handed Cam Schlittler.
