ANAHEIM, Calif. (AP) — Los Angeles Angels slugger Albert Pujols is likely to miss the rest of his 18th major league season after undergoing surgery on his left knee.

Pujols ranks sixth with 633 career homers after passing Ken Griffey Jr. last month. And he is seventh with 1,982 RBIs, just behind Lou Gehrig and Barry Bonds.

The three-time NL MVP will be 39 years old when next season begins. He still has three seasons remaining on his 10-year, $240 million contract.

Pujols spent the summer of 1999 in Hays, playing third base for the Hays Larks.
