Miami Marlins third baseman Martin Prado is expected to miss the start of the regular season after straining his right hamstring at the World Baseball Classic.
Marlins manager Don Mattingly already has ruled out Prado playing in any exhibition games.
"Obviously, it's never good, but I'm encouraged it's a Grade 1," Mattingly said Sunday at Marlins camp in Jupiter, Florida. "From there we just kind of wait until he's ready, honestly. We hope that he misses as little as possible, but we're going to definitely err on the side of caution."
A Grade I strain is considered the least severe.
Playing for Team Venezuela, Prado injured his hamstring running out a grounder in the sixth inning of Wednesday's loss to the United States.
The Marlins are not attaching a timeline to his return to the lineup.
"We say, oh, he's only going to miss two weeks, then that two weeks comes and he's thinking, 'I've got to be ready by then' and if he's not quite ready then he's just not quite ready," Mattingly said. "I'd rather say we are going to get him healthy, make sure he's healthy."
The Marlins open the regular season April 3 at Washington.
The 33-year-old Prado is the only Marlins starter over 30, and he serves as the unofficial captain of the club. A career .293 hitter, Prado batted .305 and drove in 75 runs last season.
In Prado's absence, utility players Derek Dietrich and Miguel Rojas will handle most of the work at third base. Dietrich hit .279 with seven homers in 351 at-bats last season, and Rojas hit .247 in 194 at-bats.
