Injuries are a problem for a number of key players, and it starts with New York Yankees third baseman Alex Rodriguez, who may not play at all this season.
Yankees general manager Brian Cashman raised the possibility Friday that Rodriguez could miss the entire 2013 season after undergoing hip surgery last week.
The Yankees announced after the surgery that the recovery time was expected to be six months and targeted Rodriguez's return after the All-Star break in July. But Cashman appeared to hedge on that projection in an interview with WFAN.
"Yeah, I think because (of) the serious nature of the surgery and the condition that he's trying to recover from, you know, there is that chance," Cashman told the New York radio station. "There are no guarantees in this stuff."
Cashman has no doubt the 37-year-old will put in the rehab work necessary to get back on the field as soon as possible.
"Best case scenario, yeah, he should be back," Cashman said. "Worst case scenario is he won't be back, or there might be something between."
---Milwaukee Brewers first baseman Corey Hart underwent surgery on his injured right knee, and he will be out three to four months.
Earlier in the week, Hart said he hoped to postpone surgery while he sought a second opinion, hoping to play through the injury this season. But the Brewers announced that Dr. William Raasch went ahead with the surgery, which involved debriding the knee joint surface and repairing a small meniscal tear.
Hart, 30, is coming off a strong 2012 season when he hit .270 with 30 homers and 83 RBI.
---Free-agent right-hander Carl Pavano ruptured his spleen in a fall while shoveling snow in the driveway of his home in Vermont and will need six to eight weeks to recover, FOXSports.com reported.
With training camps set to open in a few weeks, Pavano has yet to sign with a team for 2013 and won't be ready for the start of spring training if a suitor comes calling.
The injury-plagued pitcher made only 11 starts for the Minnesota Twins last season because of a bone bruise and sore right shoulder, going 2-5 with a 6.00 ERA.
---Reliever David Robertson agreed to a one-year, $3.1 million contract with the New York Yankees.
Robertson, who was eligible for arbitration, is considered one of baseball's best setup men. Working 60 2/3 innings in 65 games last season, he had 30 holds and two saves while posting a 2.67 ERA with 19 walks and 81 strikeouts.
---The Kansas City Royals claimed catcher George Kottaras off waivers from the Oakland A's.
Kottaras had signed a one-year, $1 million contract this month with Oakland to avoid arbitration. The Royals will be bound to that salary in 2013.
In 85 games last season with the Milwaukee Brewers and Oakland, Kottaras hit .211 with nine home runs and 31 RBI.
---Right-hander Jair Jurrjens has agreed to a one-year deal with the Baltimore Orioles.
Jurrjens's base salary will be $1.5 million. Additional incentives could increase the value of the contract to $4 million, CBSSports.com reported.
The 26-year-old Jurrjens posted a 3-4 record with a 6.89 ERA in with the Atlanta Braves last season.
