BOSTON - Hall of Famer Carl Yastrzemski, the last player to hit for the Triple Crown, was resting comfortably Tuesday night after having triple bypass heart surgery.

Yastrzemski, who turns 69 on Friday, had the operation at Massachusetts General Hospital, where he underwent tests after experiencing chest pains in the morning, said his spokesman, Dick Gordon.

The popular Yaz was an 18-time All-Star and spent his entire career with the Boston Red Sox, taking over left field for Ted Williams in 1961 and playing through 1983.

In 1967, Yastrzemski helped revitalize the flagging franchise during the “Impossible Dream” season when the Red Sox went from ninth place in the 10-team AL in 1966 to the World Series, where they lost to the St. Louis Cardinals.

With calls of “Yaz” echoing around Fenway Park, he won the Triple Crown that year, hitting .326 with 44 home runs and 121 RBIs.

Yastrzemski was elected to the Hall on the first ballot in 1989. He has often shied away from celebrity and rarely made public appearances, but drew a big ovation when he threw out the first ball before Game 1 of last year's World Series, won by Boston in a four-game sweep over Colorado.

Yaz finished with 452 career home runs and 1,844 RBIs. He had 3,419 lifetime hits and batted .285. He also won seven Gold Gloves, expertly playing the caroms off the Green Monster.

Yastrzemski is one of five former Red Sox players to have his number retired by the team.

His No. 8 is painted on the facing of the right field grandstands at Fenway, along with those of Williams, Carlton Fisk, Bobby Doerr and Joe Cronin.

Former Orioles pitcher Jim Palmer, another Hall of Famer, faced Yastrzemski more than any batter.

Yastrzemski's 197 plate appearances, 169 at-bats, 41 hits and 13 doubles where more than any other player had against Palmer, who held him to four homers, 21 RBIs and a .243 batting average.

“He could do everything,” Palmer said Tuesday. “He could run the bases. He could hit for average. He could hit for power. He could hit your best pitch and he could hit your worst pitch. ... I just tried to keep the ball in the ballpark against him. Sometimes it worked, sometimes it didn't.”
