Jamie Moyer isn't ready for the rocking chair just yet. The veteran lefthander signed a minor-league contract with Baltimore on Wednesday and was assigned to triple-A Norfolk.

Colorado released the 49-year-old former Phillie last month, a little over a month after he became the oldest pitcher ever to win a major-league game as a starter.

Surgery set

Yankees closer Mariano Rivera said the blood clot in his right calf has cleared up, and he will have surgery on his right knee June 12. Baseball's career saves leader suffered a torn anterior cruciate ligament and damaged meniscus while shagging fly balls on May 3.

Top pick to sign

Astros owner Jim Crane said top overall draft pick Carlos Correa is expected to sign on Thursday.

Crane revealed that the team had a verbal agreement with the 17-year-old Puerto Rican shortstop when the Astros drafted him on Monday.

Around the bigs

Just nine months after throwing his first pitch as a professional and two months after beginning the season in single-A, former first baseman Sean Doolittle made his major-league debut as a reliever for Oakland against Texas on Tuesday night. The lefthander struck out the first three batters he faced.

Lefthander Andy Pettitte is 3-1 at Yankee Stadium since his return from retirement. In four home starts he's allowed just six runs, a 1.88 ERA.

The Reds sent infielder Mike Costanzo to triple-A Louisville. The Archbishop Carroll grad appeared in 17 games and was hitless in his last 11 at-bats, going 1 for 18 overall.

The Mets activated outfielder Jason Bay from the 15-day disabled list (rib fracture) and placed righthander Chris Young on the paternity list.

The Tigers put catcher Alex Avila on the 15-day disabled list with a right hamstring strain.

Righthander Daisuke Matsuzaka is expected to start for the Red Sox on Saturday against Washington, one day short of a year after he had reconstructive surgery on his elbow.

White Sox first baseman Paul Konerko was sidelined for a second straight game Wednesday against the Blue Jays after having a procedure to flush a bone chip out of a joint in his left wrist.

The Orioles used a 20th-round pick to draft Ryan Ripken, son of Hall of Fame infielder Cal Ripken Jr. The 18-year-old is a 6-foot-6 first baseman from the Gilman School in Baltimore. He has a full ride to defending College World Series champion South Carolina.
