Chris Volstad hurt his chances at solidifying a spot in the Marlins' rotation, allowing four runs in 2 1/3 innings in Florida's 5-4 victory over the Twins Monday.
Volstad allowed five hits and four walks. He has given up eight runs on 11 hits and five walks in his last two outings.
The right-hander is one of six candidates for three spots in the Marlins' rotation behind Josh Johnson and Ricky Nolasco. One of those spots appears filled by Anibal Sanchez after his four scoreless innings against the Mets Sunday.
Marlins prospect Mike Stanton had his third homer of the spring, a two-run shot in the third off Twins starter Francisco Liriano, who pitched three innings, allowing three runs on four hits. He struck out six.
The Marlins rallied from a 4-1 deficit. Donnie Murphy drove in the winning run with a two-out single in the sixth.
n Orioles 8, Red Sox 4: Mike Lowell made his spring training debut for Boston at an unfamiliar position.
Lowell, who had surgery Dec. 30 to repair a torn ligament in his right thumb, played first base in a loss to Baltimore. It was his first appearance at the position since 1998, when he played four games there for the New York Yankees' Triple-A affiliate.
Boston's offseason acquisition of third baseman Adrian Beltre will limit Lowell's time at the position he had manned for the Red Sox since 2006.
Lowell batted second and went 1-for-2 with a single to right in his first at-bat.
Red Sox starter Tim Wakefield took the loss, allowing five runs and nine hits in 3 2/3 innings.
