Hernández was born in Cuba and now lives in Florida. In 2015 he returned to Cuba for the first time since he left to spread the ashes of his father. A few months later he returned to umpire the first game in the country involving an MLB team since 1999. Hernández also does charity work for disabled children, including hosting a celebrity golf tournament every year.
Umpiring career
Hernández umpired in the World Series in 2002 and 2005, as well as the All-Star Game in 1999, 2009, and 2017. He has officiated in seven League Championship Series, and in ten League Division Series. Hernández also worked Game 7 of the 2008 ALCS as an injury fill-in for Derryl Cousins. For the second half of the 2011 baseball season, Hernández was moved from the umpiring crew of Joe West to the crew of Gerry Davis. Hernández wore number 5 while in the National League, but the number was taken by Dale Scott when the umpires were consolidated under MLB in 2000, so Hernández took number 55. After Scott's retirement in 2017, Hernández regained his number 5 for the 2018 season. In 1999 Hernández was ranked 31st out of 36 in the Major League Baseball Players Association survey. He was retained for the 2000 season ahead of 13 of his National League colleagues, which the Philadelphia Inquirer termed one of the "surprises" of the 1999 purge. In 2006 and 2011 he was listed as the third-worst umpire in Sports Illustrated polls and a 2010ESPN survey showed that 22% of major league ballplayers asked identified Hernández as the worst umpire in the major leagues. In 2016, MLB rated Hernández' accuracy behind the plate at 96.88 percent, and said he didn't miss any calls on the basepath.
Incidents and notable games
In 1998, Hernández was behind the plate for a game between the Mets and the Braves, the day before the All-Star break was to begin. In the 11th inning Braves runner Michael Tucker tagged up on a fly ball to left. Replays showed the throw to catcher Mike Piazza clearly beating Tucker and that Tucker never touched the plate but Hernández ruled Tucker safe. After the game Piazza called the call the worst he'd ever seen in his baseball career and other Mets opined that Hernández may have been in a hurry to get the game over with so they could all start their break. In 2001, Hernández was blamed for ejecting Steve McMichael, a former Chicago Bears football player, who had taken a shot at Hernández's umpiring over the Chicago Cubs PA system after being introduced as the guest singer for "Take Me Out to the Ball Game". It was later revealed crew chief Randy Marsh had ordered the ejection. On July 17, 2006, Hernández was the third base umpire and ejected Dodgers' first base coachMariano Duncan. When Duncan came out of the dugout to argue the ejection, he tossed his cap onto the ground in anger. After Duncan was removed from the field, Hernández picked up the cap and tossed it to a fan in the stands. The next day, Duncan taped his cap to his head before delivering the Dodgers' lineup to the umpires. Duncan was suspended for two games and fined by Major League Baseball as a result of the incident. Hernández was behind the plate for the final game at the old Yankee Stadium on September 21, 2008. He was umpiring at third base when Jered Weaver threw a no-hitter on May 2, 2012, and Hernández was the third base umpire on September 28, 2012, when Homer Bailey of the Cincinnati Reds no-hit the Pittsburgh Pirates. On May 8, 2013, Hernández served as the crew chief for a game between the Oakland Athletics and the Cleveland Indians. In the ninth inning he and two other umpires ruled a long hit by the Athletics' Adam Rosales as a double following a video review. Oakland's manager Bob Melvin argued the call, and Hernández ejected him from the game. The Athletics lost the game 4–3. MLB later acknowledged that the hit should have been called a home run but said that it was too late to overturn it. Several umpires argued that the replay system did not provide clear enough pictures and the system was later changed. In August 2017, Detroit Tigers second baseman Ian Kinsler was fined $10,000 by MLB, for critical comments he made about Hernández; Kinsler had said that Hernández was a bad umpire and "needs to find another job". During the 2016, 2017, and 2018 seasons, Hernández's calls at first base were overturned in 14 out of 18 video reviews, for a 78% overturn rate, exceeding the 60% overturn rate for all first-base calls during that time period. On October 8, 2018, Hernández was the first base umpire for Game 3 of the 2018 American League Division Series between the Yankees and Red Sox. Four out of five plays that he called which were submitted for video review were overturned. TBS analyst and Hall of FamerPedro Martínez said after the game: "Angel was horrible. Don't get me going on Angel now. Major League Baseball needs to do something about Angel. It doesn't matter how many times he sues Major League Baseball. He's as bad as there is." Hernández declined to comment after the game, a blowout win for the Red Sox, but MLB issued a statement through a spokesperson: "There were several very close calls at first base tonight, and we are glad that instant replay allowed the umpiring crew to achieve the proper result on all of them." On April 8, 2019, Boston University published a study on 11 seasons of Major League Baseball data, almost 4 million pitches culled and analyzed, to determine the accuracy of balls and strikes called. The study found that Hernández performed stronger in 2018 than his average for 2008–2018. He averaged 19 incorrect calls a game, or 2.2 per inning. Even with this high error rate, compared to his peers, he performed better than others, escaping the 2018 Bottom 10 MLB list. During Spring training 2019, Hernández claimed he gets four wrong calls per game. The BU study shows that his error rate is almost five times higher.
Lawsuit
In July 2017, Hernández filed a federal lawsuit against MLB, alleging racial discrimination led to him being overlooked for World Series games and crew chief promotions. He also cited a long-standing feud with Chief Baseball Officer Joe Torre, dating back to Torre's managerial career. Hernández asserted that prior to Torre's arrival in 2011, Hernández's evaluations were consistently positive, but since then evaluations have turned neutral or negative. Nearly a week after he filed the suit, Hernández was named to the 2017 All-Star Game; he was also selected as first base umpire for the 2017 and 2018 American League Division Series. In September 2018, the case was moved from the United States District Court for the Southern District of Ohio to the United States District Court for the Southern District of New York in New York City, where Major League Baseball is headquartered.
