SCOTTSDALE, Ariz. -- Rockies first baseman Todd Helton experienced swelling in his right knee Saturday morning, the result of a twist he suffered during Friday night's game against the Royals, which was called after four innings because of rain.
Helton, 39, underwent surgery last November to have cartilage repaired. It was his second surgery of the year. He had a torn labrum repaired in August and missed the remainder of the season.
Helton was in the trainer's office at Salt River Fields at Talking Stick on Saturday morning and did not accompany the team to the afternoon game against the Angels at Tempe Diablo Stadium.
Friday night was Helton's third appearance of Spring Training, although the rainout means he officially has been in two games, and is 1-for-4 with a double and one RBI.
