Marlins outfielder Cameron Maybin left today’s spring training game against the Nationals early after feeling tightness in his left hamstring. Maybin said the move was a precautionary one.

Maybin reached base on an error in the ninth inning, but pulled up to first base gingerly and was removed for a pinch-runner. Acquired from the Tigers in the off-season in the Miguel Cabrera trade, Maybin is competing for the starting center field job with the major league team and is the No. 6 prospect in baseball.

Tigers top prospect Rick Porcello, the Tigers’ first-round pick last year, saw his first action of the spring in a game against the Blue Jays. The 19-year-old righthander retired all six batters he faced without allowing a ball to leave the infield. Porcello, who was 19 months old when Frank Thomas made his big league debut in 1990, struck out Thomas for his only strikeout of the game.
