The Cubs want Prior to be able to throw 90-100 pitches before they activate him.
If all goes well, he could be reinstated June 3.
"For the first time, I felt like if I was ready to go five, six innings, I could have gotten big league hitters out," said Prior, who won 18 games last season. "I was hitting some spots and had some good life on my pitches.
"I was much more relaxed and my arm is starting to come along. Today, I felt much better."
Sidelined all spring with an inflamed Achilles tendon and a sore pitching elbow, Prior is expected to join the Cubs in Los Angeles this week for a bullpen session with pitching coach Larry Rothschild.
Contreras had a light bullpen session Monday supervised by team
vice president and pitching guru Billy Connors at the Yankees'
spring training complex. The pair were to fly to Columbus following
The 32-year old Contreras has been working with Connors since
Friday. He was optioned to Class-A Tampa last Wednesday, one day
after allowing six earned runs and four hits in two-plus innings of
New York's 10-8 win over Oakland.
Meanwhile, left-hander Felix Heredia, on the 15-day disabled list because
of a bruised left index finger, could begin a rehabilitation assignment this week with Columbus.
Reliever Steve Karsay reported no problems after throwing 48
pitches Monday in his first bullpen session since experiencing tightness in his surgically repaired right shoulder last month. He had rotator cuff surgery a year ago and is expected to rejoin the Yankees this season.
Orlando Hernandez could resume throwing off flat ground later
this week. He had a cortisone shot last week for bursitis in his
Wagner told the Philadelphia Inquirer that it hurt even to talk to his wife on the phone.
"I couldn't breathe or do anything," Wagner, who was unavailable in Sunday night's finale against the Diamondbacks, told the Inquirer. The Phillies hope he's available to pitch Tuesday in San Francisco.
Wagner said any spasms he's had in the past usually last a day, but added these are the worst.
Baltimore Orioles: Second baseman Jerry Hairston will be activated from the DL on Tuesday when the team starts a three-game series at the White Sox. According to The Baltimore Sun, manager Lee Mazzilli has tentative plans to bat Hairston ninth as the DH.
"Nothing is permanent," Mazzilli told The Sun, "but that's what I see right now."
Brian Roberts has exceled at second base in Hairston's absence, batting .315 with 11 doubles and an AL-leading 15 stolen bases.
Hairston finished his injury rehabilitation assignment at Double-A Bowie on Sunday. He fractured the knuckle on his right ring finger stealing a base in the first inning of the Orioles' first spring training game. Hairston played only 58 games last season.
Catcher Rob Bowen will return to Double-A New Britain when LeCroy, the Twins' Opening Day DH, is activated. LeCroy is expected to share catching duties with Henry Blanco and rarely be used as DH. Twins manager Ron Gardenhire wants to avoid using LeCroy as DH with Blanco catching.
"I really hate to do that," Gardenhire was quoted as saying in the Minneapolis Star Tribune. "I know I may have to do it a couple times, but I don't like that."
Meanwhile, infielder Nick Punto is expected to go on the 15-day DL because of a strained right oblique muscle.
Perez, 34, ruptured his left Achilles tendon while trying to stretch a double into a triple in the fifth inning of the Devil Rays' 8-4 loss to the Angels on Sunday.
Perez, the Rays' most experienced bench player, signed a two-year, $1.5 million contract this offseason.
Perez, who will likely need to undergo surgery for the injury, was to be evaluated by Devil Rays orthopedist Koko Eaton on Monday. His recovery, including surgery, a period of immobilization and rehabilitation, could take up to a year, according to the Tribune.
The right-hander, who agreed to a $5 million, two-year deal in
December 2002, is 0-3 with a 9.60 ERA in four starts and one relief
appearance for Cincinnati this season. The Reds last week demoted
him from the starting rotation to the bullpen.
The Reds first signed Haynes as a free agent in January 2002. He
went 15-10 that year to lead the team in wins, starts (34), innings
pitched (196 2-3) and strikeouts (126).
But in 2003, he started Cincinnati's season opener and lost 10-1
to Pittsburgh. He finished the season 2-12 with 94 1-3 innings
pitched. He was on the disabled list twice and ended his season in
early August because of a bulging disc in his lower back.
The Reds were off Monday. They plan to fill Haynes' roster spot
before their game Tuesday night in San Diego.
