David Jeans knew little to nothing about Tanner Griffith when he entered De La Salle-Concord as a freshman. Few did. He was a Livermore kid. Quiet but confident, Jeans quickly learned. Unassuming. Good body language.
“He definitely didn’t pass the eye test,” said Jeans, who just finished his 12th season as the school’s baseball coach. “He wasn’t someone you looked at and said, ‘Oh, he’s a major D1 guy.’ ”
But after four years, and having led the Spartans to a second straight Northern California Division 1 title as the team’s fleet and punchy right fielder, the eyes see something different in Griffith now.
Same body. Same quiet, confident demeanor. But now a bonafide Division I player, a St. Mary’s signee, and The Chronicle’s 2023 All-Metro Baseball Player of the Year.
The 5-foot-9, 160-pound Griffith led the Chronicle No. 1-ranked Spartans (27-5) in batting average (.435), on-base percentage (.557), runs (41), hits (40), doubles (14) and home runs (four).
Utilizing elite speed, he played a flawless right field, just as he did as a junior highlighted by making one of the great catches in Jeans’ tenure during a 7-6 comeback win over St. Francis in the 2022 NorCal D1 title game.
De La Salle came back from a three-run deficit in the final inning to win that one in a walk-off. Earlier this month, the Spartans did the same, but on the road, scoring six runs in the seventh, capped by a grand slam by Hank Tripaldi, to win 11-8 at Valley Christian.
Griffith reached base four times in that game and scored twice, capping a highly productive postseason in which he went 12-for-22 and reached base 20 times with 14 runs, 10 RBIs, three doubles and a homer in seven straight wins. That extended De La Salle’s remarkable postseason win streak since 2016 to 30 games, which is part of six consecutive North Coast Section titles.
Jeans said Griffith is the poster child for the program’s victorious process and results.
“He’s just a winner,” Jeans said. “He’s one of those guys who just finds a way to win. He takes a walk, hits for power, makes a throw, makes a spectacular catch. He came in not as a big-time guy, but he kept grinding and got better and better and better. You want Tanner Griffith on your team.”
He arrived at De La Salle as a second baseman, a position he had played since he was a child. His idols were diminutive middle infielders — Jose Altuve and Francisco Lindor — but accepted the challenge of a position change, along with all the other adjustments that come from living in a different community.
He was expected to attend Livermore High, but at the last minute convinced his parents that De La Salle and its “Spartan brotherhood” would be the best path.
“It was kind of crazy going to a new school and dealing with all the social adjustments and playing a new position,” Griffith said. “But from the beginning it felt right. I loved the culture. I like challenges in my life and being able to overcome them.”
He’s overcome the eye-test doubters by “always playing with a chip on my shoulder, and trying to work twice as hard as everyone else.”
It all paid off, starting for a team that has been nationally ranked and won 54 games combined the past two seasons, ending each with improbable late wins.
“It’s been surreal,” Griffith said. “They were both like college games, so loud and filled with so many twists and emotions. Going out as a two-time NorCal champion with such great teammates and coaches is something I’ll never forget.”
Jeans thinks the left-hand hitting Griffith (he throws right) will excel at the next level.
“About 70 percent of the guys we face are major D1 guys and he’s never over-matched,” he said. “He really controls the zone. He doesn’t chase and if the ball is in the zone, he hammers it.”
