NEW YORK — LHP Johan Santana went on the 15-day disabled list Saturday with a sprained right ankle, another setback for the fading Mets since the All-Star break.
Santana, 33, has struggled mightily since the Cubs' Reed Johnson stepped on his foot July 6 on a play at first base. He was hit hard for the third straight start Friday night in a 7-6 loss to the Dodgers, and manager Terry Collins said afterward the team was looking for a way to get some "energy" back in his arm.
Santana missed last season after major shoulder surgery. He is 6-7 with a 3.98 ERA in 19 starts covering 110 2/3 innings.
"We knew in spring training that there might be a time this summer when he has to get shut down," Collins said. "Well, now is going to be that time."
General manager Sandy Alderson said Santana probably won't pitch until at least Aug. 7.
New York is also missing RH starter Dillon Gee, who had surgery last week on an artery in his pitching shoulder and could be out for the season. RHP Mike Pelfrey had season-ending elbow surgery in May.
CHISOX boost pen: The White Sox acquired Astros RH reliever Brett Myers for two minor-league pitchers and a player to be named.
Myers, 31, had 19 saves and a 3.52 ERA for Houston this season and will try to bolster an inexperienced bullpen. RHP Addison Reed, Chicago's 23-year-old closer, has 15 saves but a 4.24 ERA.
White Sox general manager Kenny Williams said Myers would not be Chicago's closer.
"In no way, for (manager Robin Ventura) or myself or in any way, is this a lack of confidence in Addison Reed," Williams said.
Houston received RHP Matt Heidenreich and LHP Blair Walters.
GARZA PULLED EARLY: Cubs RHP Matt Garza was taken out after working three scoreless innings against the Cardinals with cramping in his right triceps, an injury that wasn't obvious and prompted speculation that he had been traded. The Cubs said X-rays on the former Rays starter were negative.
CARDS STAYING IN: Cardinals general manager John Mozeliak said the World Series champions will be buyers at the trade deadline despite a slow start to the second half.
PITCHER POWER: Giants RHP Matt Cain and Phillies LHP Cole Hamels became the first pitchers to homer off each other in one game since Braves RHP Kevin Millwood and Rockies RHP Denny Stark on May 18, 2002. They became the first pair to do it in the same inning since Expos RHP Kevin Gross and Dodgers LHP Fernando Valenzuela on May 14, 1990.
BRAVES: OF Matt Diaz went on the 15-day disabled list with a bruised right thumb. LH reliever Jonny Venters, out since July 5 with an impingement in his pitching elbow, was activated from the DL.
INDIANS: RHP Roberto Hernandez received a visa to return to the United States from the Dominican Republic and will serve a three-week suspension for age and identity fraud from Major League Baseball before he can rejoin the team. The former Fausto Carmona is 31, three years older than his listed age.
NATIONALS: RF Bryce Harper left the game against the Braves in the first inning with a sore left ankle after fouling a ball off the ankle. X-rays were negative, and the rookie is day to day.
RED SOX: The team honored former captain Jason Varitek, giving the longtime catcher the home plate from his final game at Fenway Park and a red pickup truck in a pregame ceremony.
TWINS: 1B Justin Morneau was placed on the paternity list. Morneau and his wife, Krista, are expecting their second child.
