MESA, Ariz. -- Mariners third baseman Kyle Seager was scratched from Saturday's game against the Cubs at Sloan Park due to some muscle tightness in his side, but manager Lloyd McClendon said he was merely being extra cautious with his All-Star infielder.
Seager, 27, was at Mariners camp Saturday morning and did some work in the batting cage, but didn't make the trip with the team to Mesa for the afternoon contest.
"We didn't want to take a chance," McClendon said. "He was fine and passed all the tests and stuff, but it's just too late in spring to even think about taking a chance. He's fine. He checked out OK. I just did it as a precaution."
Carlos Rivero, a non-roster invitee who played for the Red Sox last season, got the start at third base in Seager's absence and went 0-for-4 in the 12-10 loss.
Seager, an American League All-Star last season, is hitting .400 in 10 Cactus League games with one home run and five RBIs in 25 at-bats.
