Brent Rooker did not get recalled when Minnesota needed an outfielder to replace the injured Byron Buxton. The Twins went with Gilberto Celestino, their No. 6 prospect, to fill Buxton’s spot in center field. Former Mississippi State standout Rooker, a corner outfielder (and the No. 10 prospect), remains at Triple-A St. Paul. Celestino, who hit .121 in 11 games with the Twins this month, was just sent down to Triple-A on Friday when Buxton was activated from a previous stint on the IL. Rooker opened the season in the big leagues and batted .103 in eight games. He has been in Triple-A since May 3, batting .225 with 10 homers and 21 RBIs in 35 games and apparently seeing some encouraging signs. “When I’m going good I can use all parts (of the field) and drive the ball to all fields pretty well,” Rooker said in a twincities.com story after hitting his 10th homer, to the opposite field, last Saturday. “One of my strengths is being able to hit the ball out of any part of the ballpark.” He has 64 minor league home runs over parts of four seasons and two big league homers.
