JUPITER, Fla. -- Before Wednesday's game, Marlins manager Mike Redmond claimed there is not a "bigger" three-four lineup combination than Giancarlo Stanton and Michael Morse. The two sluggers showed their clout in an 8-0 win over the Nationals at Roger Dean Stadium.
Morse connected on a three-run homer off Jordan Zimmermann in the first inning, and Stanton blasted a two-run shot in the second.
Zimmermann, who will be Washington's No. 2 starter, had a rough Spring Training finale, giving up eight runs (seven earned) on nine hits in four innings. The right-hander threw 80 pitches.
"It was good to see those guys get some big hits against a great pitcher," Redmond said. "We came out aggressively today. Got some big hits, had some guys on base and put some pressure on them. It was a good win, and especially nice to finish Spring Training on a positive note with a big win."
Miami right-hander Jarred Cosart was impressive over six shutout innings, allowing one hit while striking out four and walking three. Cosart, making his first start since March 22, has been treating a blister on his right middle finger. He logged 78 pitches, 49 for strikes.
The Marlins pounced on Zimmermann early, with the meat of the order doing the most damage. An inning after Morse connected on his three-run shot, Stanton's blast was a no-doubter that landed on the roof of the Marlins' building located beyond the left-field wall. Christian Yelich added a two-run triple in a four-run second inning.
The lone hit Cosart allowed was a first-inning double by Yunel Escobar.
Up next: The Marlins wrapped up their Grapefruit League schedule on Wednesday. The club is off on Thursday, and it heads to Greensboro, N.C., on Friday to face its low Class A affiliate, the Grasshoppers. Tom Koehler, expected to be Miami's No. 3 starter, will start and throw about 80 pitches.
