David Lee Henderson (born July 21 1958 in Merced, California), nicknamed Hendu, is an American former Major League Baseball player who played for the Seattle Mariners (-), Boston Red Sox (1986-), San Francisco Giants (1987), Oakland Athletics (-) and Kansas City Royals (). He batted and threw right-handed.
Henderson helped his teams reach the World Series four times during his career (1986 with Boston, 1988-1990 with Oakland). However, his only World Championship ring came in 1989, when the A's swept their Bay Area rivals, the San Francisco Giants.
When Henderson stepped to the plate, there were two outs and a runner on first base (catcher Rich Gedman). On a 2-2 count with the Red Sox down to their final strike in the series, Henderson, who had entered the game as a replacement for an injured Tony Armas, hit a drive off pitcher Donnie Moore that kept the Sox alive.
Henderson began to jump for joy, even running backwards for a few steps, while making his way down the first base line as he watched the ball sail over the outfield fence, having just smacked possibly the most stunning clutch homer since Bobby Thomson in . The home run also saved Henderson from possibly being a scapegoat, after Bobby Grich's sixth-inning warning track fly ball deflected off his glove and over the wall for a two-run home run that gave the Angels a 3-2 lead. The ball hit the palm of Henderson's glove an instant before his wrist hit the fence, dislodging the ball and sending it over the fence. The Angels were able to tie the score up at 6-6 in the bottom of the ninth, but in the 11th inning, Henderson hit a sacrifice fly that would prove to be the margin of victory. Still down 3 games to 2, the Red Sox returned home to Fenway Park for the final two ALCS games, where they defeated the devastated Angels 10-4 and 8-1 to win the series.
Selected for the 1991 All-Star Game, Henderson was on his way to the best season of his career, batting in the number-two spot in the A's lineup behind Rickey Henderson (no relation). The slugger was consistently getting fastballs to hit because the speedy Rickey was a stolen base threat every time he reached safely. Henderson was batting .340 before the All-Star break, but his average dipped in the second half of the season and he finished the year at .276, though he did hit a career-high 25 home runs. That year, Henderson blasted three home runs in consecutive at-bats against Minnesota.
While he did come back to hit 20 home runs in , Henderson was never the same player after blowing out his knee the previous season. He finished up his career as a reserve player with the Kansas City Royals in .
