Troy Tulowitzki to undergo groin surgery - MLB

The Rockies finally know what’s ailing Troy Tulowitzki; he was diagnosed with a kind of athletic pubalgia most commonly known as Hockey Goalie/Baseball Pitcher Syndrome after another examination Wednesday. He’ll undergo surgery Thursday, and there is no timetable for his return.

Hockey Goalie/Baseball Pitcher Syndrome is one of a number of different versions of athletic pubalgia, which are injuries that involve tears in the groin areas. My 15 minutes of research indicates that it takes about eight weeks to recover from the surgery, meaning Tulo should be able to make it back at some point this season, even if it’s just for September.

With Tulowitzki sidelined, the Rockies likely just went from probable to definite sellers in advance of the trade deadline. They’re currently 25-41, putting them 16 games back of the Dodgers in the NL West.

Tulowitzki was hitting .287/.360/.486 with eight homers and 27 RBI before he landed on the disabled list May 31. His absence has caused the Rockies to slide Marco Scutaro from second base to shortstop, with Chris Nelson taking over at second.

LOS ANGELES — Giancarlo Stanton, Josh Donaldson, and Tommy Kahnle were activated by the New York Yankees ahead of their weekend series against the Los Angeles Dodgers.

New York cleared three roster spots after a 1-0 loss at Seattle, optioning infielder-outfielders Oswaldo Cabrera and Franchy Cordero to Triple-A Scranton/Wilkes-Barre along with left-hander Matt Krook.

Stanton, Donaldson and Kahnle all played in a rehab game for Double-A Somerset. Stanton was hitless in three at-bats in his first appearance since injuring his left hamstring on April 15.

Donaldson went 1 for 4 in his fourth rehab game as he comes back from a strained right hamstring originally sustained on April 5.

Kahnle pitched one inning, giving up one run and one hit and walking two. He has been out since spring training with right biceps tendinitis.

Aaron Boone said he wasn’t concerned about Stanton returning after playing in just one rehab game. He did say that Stanton likely will be a designated hitter for a couple of weeks after rejoining the Yankees.

New York is missing centerfielder Harrison Bader, who strained his right hamstring against the Mariners and went on the injured list the next day.

Left-hander Carlos Rodón, sidelined since spring training by a sore left forearm and an ailing back, was transferred to the 60-day injured list.
