KISSIMMEE, Fla. — Roger Clemens might show up at Houston Astros spring training this week for a minor league minicamp that includes his son, Koby.

The minicamp begins Monday in Kissimmee and Koby Clemens, a catcher in the Astros' minor league system, is expected to participate. Minor leaguers could check in for the camp on Sunday, but neither Koby nor his father arrived before the minor league clubhouse closed at 5 p.m.

Roger Clemens has come to the spring camp with his son the past few seasons. He has a personal services contract with the Astros that will kick in when he officially retires.

Houston manager Cecil Cooper said he was expecting the seven-time Cy Young Award winner to attend the camp, but said he didn't know when he might arrive.

DEROSA SIDELINED: Chicago Cubs second baseman Mark DeRosa was released from the hospital Sunday, the team said, one day after complaining of a rapid heartbeat during fielding drills. Cubs spokesman Peter Chase announced DeRosa's release shortly after 5 p.m. Sunday. DeRosa is expected to be examined by a cardiologist Monday and could be back on the field by the middle of the week, the Cubs said. His irregular heartbeat was not life-threatening, according to the team.

PIRATES SIGN KIM: Free-agent pitcher Byung-Hyun Kim finalized an $850,000, one-year contract with the Pittsburgh Pirates on Sunday, four days after agreeing to terms. The Pirates also designated infielder Ray Olmedo for assignment. Kim, expected to join the team Monday, could earn up to $1.15 million in performance bonuses based on games pitched. His deal guarantees him $300,000.

MINOR LEAGUE DEAL: Shannon Stewart and the Toronto Blue Jays agreed to a minor league contract Sunday with an invitation to spring training. The right-handed hitting outfielder spent last season with the Oakland Athletics, batting .290 with 12 homers and 48 RBIs in 146 games. Stewart, who turns 34 on Monday, is a career .298 hitter with 566 RBIs, 193 stolen bases and an on-base percentage of .362.

SANCHEZ SET TO PITCH: At Port St. Lucie, Fla., Johan Santana is expected to make his first spring training start for the New York Mets on Friday against St. Louis. Before that, the team will get a good look at reliever Duaner Sanchez. The right-hander is scheduled to pitch in an intrasquad game Monday, a big step in his recovery from shoulder surgery last spring. He hasn't appeared in a major league game since a July 2006 taxi accident.

FRANCONA GETS NEW PACT: After managing the Boston Red Sox to two World Series championships in four seasons, Terry Francona was rewarded Sunday with a three-year contract extension that runs through 2011. The deal includes club options for 2012 and 2013, which would give him a full decade as manager if the team exercises them. Francona also received something else: a touching e-mail from general manager Theo Epstein as final details were being worked out Saturday night. "It was just personal (about) what we've been through since the very beginning," Francona said after Sunday's spring training workout. "It meant a lot to me. He means a lot to me."
