He is eight weeks into an offseason that began way too early, eight weeks removed from his lowest victory total in seven years, and the highest ERA of his career. Carsten Charles Sabathia doesn’t want to hear about the injuries or the musical third basemen or how desperately the Yankees missed their captain, Derek Jeter. “It’s nobody else’s fault but mine (that we didn’t make the postseason),” Sabathia says. “That’s how I look at it. Four or more wins from me and we’re in the playoffs and that’s the bottom line.” The Yankees erstwhile ace is sitting on a couch with his wife, Amber, in their spacious Bergen County home, complete with a full basketball court in the basement. He is talking about how good he feels — at 285, he is down 40 pounds from his peak — and how hard he is training, but mostly he is talking about sharing his good fortune with others, through the far-flung philanthropy of his PitCCh IN Foundation, which Amber Sabathia is the executive director of and which operates programs on two coasts. The Sabathias grew up in Vallejo, Calif., a hardscrabble Bay Area enclave, in one-parent, economically deprived homes. The rewards of giving back are abundant, they say, and for proof, they need look no further than a kid named Kamren Mitchell, 19, also of Vallejo. They met Kamren when PitCCh In was taking 20 kids served by an agency called Youth and Family Services on a Christmas shopping spree, each child entitled to spend $300. Kamren, an outsized kid, was having trouble finding sneakers his size. “Wait a minute... what size do you wear?” Sabathia said to him. “Fifteen,” Kamren replied. “That’s my size,” Sabathia said. “I’ve got boxes of new shoes at home that I can send to you.” Sabathia did just that, and a bond was formed. Some months later, Kamren Mitchell was going through a difficult period, having just received a letter from his father — whom he barely knows — telling him he couldn’t spend time with him. On the same day Mitchell got more boxes from the Sabathias. Kamren Mitchell saw the boxes and started to cry. He told Donna Martin, Youth Services program director, “CC doesn’t hardly know me and he cares more about me than my own father.” Sabathia mentored Kamren Mitchell, the way that Dave Stewart mentored him when Stewart was the Oakland A’s ace and visited Sabathia’s Boys and Girls Club in Vallejo. Sabathia paid for Kamren’s prom wear and outing, encouraged him to study hard, not give in to circumstances, or despair. Kamren Mitchell is now in college in northern California. “There couldn’t be a better reason for doing it,” Sabathia says. “It could be just that one kid that we make a difference in his life. That’s why we do it.” Closer to home, Aieyla Santaella, 18, is a dancer from the Soundview projects, a freshman at LaGuardia Community College. She was named the Youth of the Year for 2013 at the Madison Square Boys and Girls Club branch on E. 189th St. in the Fordham section of the Bronx — a club that PitCCh In has been very involved with over the last three years — inviting kids to its annual Christmas party at the MLB Fan Cave; to be guests at Yankee games; and to participate in the CC Challenge, Sabathia’s annual scavenger hunt in Central Park. The club has also been the recipient of the foundation’s Youth Backpack Program, the Sabathias donating backpacks stuffed with school supplies. They’ve distributed more than 15,000 backpacks to schoolchildren, at a retail value of more than $1.7 million. Santaella and her fellow dancers from the club will perform for the Sabathias at the Fan Cave in a couple of weeks — just as they have the last two years, a performance that prompted a $5,000 donation to the dance program from the foundation. Amber invited Aieyla to lunch at the Hard Rock Café at the Stadium, and follows her on Instagram. Says Aieyla Santaella, “Even though they come from a wealthy home and wealthy family, they still know how to connect with kids from the Bronx. That means a lot. To be welcomed the way they welcome us means a lot. They definitely made me realize how good it is to be humble.” Aieyla says that Amber — a mother of four who presides over the foundation, is getting a certificate in philanthropy from NYU and just launched her own line of MLB-licensed children’s clothes named CCCandy — is a woman she aspires to be like. “She manages so much. She’s definitely a good role model,” Santaella says. Elizabeth Ortiz is the cultural enrichment coordinator at the Boys and Girls club branch on E. 189th. “There are a lot of people who make donations to organizations and cancer research and other causes,” Ortiz says, “but CC and Amber are there themselves. Kids see them and connect with them. They make the kids feel so important. They really are like our extended family.” The foundation has renovated Sabathia’s old Little League Field in Vallejo, and indoor and outdoor basketball courts at his former Boys and Girls Club. The big New York initiative for 2014 is to renovate ballfields in the Bronx, according to Candy Crary, PitCCh In program director. Back in Vallejo, Amber has been the prime force behind a baby shower program for low-income mothers who are in recovery from drug and/or alcohol abuse. At this time last year, CC and Amber were hands-on in the Sandy relief effort in Hudson County, handing out coats and supplies. Barring any complication from the holiday storm, the Sabathia family plans to take in the Thanksgiving Day Parade for a fourth consecutive year, then head back home for a large family gathering. In the meantime, the pitcher in the family is thankful to have a new catcher, Brian McCann, whom he calls “a great addition to the Yankees.
