Guzman triples as Nats fall to Fish

Mock struggles in push to make starting rotation

at Jupiter, Fla.
Tuesday, March 30

Marlins at the plate: Chris Volstad not only has won a rotation spot. The right-hander collected three hits, including a double and two RBIs. In the second inning, Volstad put the Marlins on the board with a run-scoring double. Bryan Petersen, who singled, scored. Ronny Paulino's two-run double in the third made it 3-1. And in the fifth inning, the Marlins scored five runs, with three earned. Brian Barden had an RBI single, and Volstad had a run-scoring single in the inning.

Nationals at the plate: Ryan Zimmerman's double in the first inning was his 10th extra-base hit of the spring. The Nationals pulled even at 1 in the third inning, scoring an unearned run. With two outs, Nyjer Morgan reached on an error and scored on Cristian Guzman's triple. In the seventh inning, Mike Morse doubled and scored on Chris Coste's RBI single.

Marlins on the mound: Volstad enjoyed his third consecutive solid outing, working 6 2/3 innings while giving up two runs on seven hits. The right-hander struck out six and didn't walk a batter. Volstad was around the plate, throwing 92 pitches with 63 strikes. Brian Sanches, who will be used in a setup role, worked out of a first-and-third jam in the seventh.

Nationals on the mound: Garrett Mock was looking to secure the fifth starter spot. The right-hander had a rough 4 2/3 inning-outing, giving up six runs (four earned), while walking five and striking out three. Of his 96 pitches, 57 were strikes. Jason Bergmann allowed five runs and two runs in one-third of an inning.

Worth noting: There is a bit of an issue if Cody Ross will be ready for Opening Day. Ross has been out with a sore right calf, and he's been playing in Minor League games. Hanley Ramirez and Jorge Cantu were given Tuesday off. Washington's Chris Coste was claimed off waivers from the Mets, and he delivered an RBI single.

Grapefruit League records: Marlins 13-13-1; Nationals 8-18

Up next: Scratched from his past start due to a stomach virus, Josh Johnson will make his final appearance before Opening Day on Wednesday at 1:10 p.m. ET live on MLB.TV. Johnson will face the Mets at Port St. Lucie, Fla., with New York going with John Maine. Johnson likely will throw about 85 pitches in his final tuneup before facing Mets on Monday on Opening Day at Citi Field.

Left-hander John Lannan will have make his last Spring Training start against the Cardinals at 1:05 p.m., before making his Opening Day outing against the Phillies on Monday. The last time Lannan faced the Cardinals was last Friday, giving up four earned runs in 5 2/3 innings.
