Nats 11, Mets (ss) 5: Mazzoni allows 7

VIERA, Fla. -- Cory Mazzoni allowed seven eighth-inning runs as the Washington Nationals beat a Mets split squad, 11-5, Wednesday at Space Coast Stadium.

Mazzoni surrendered a three-run homer to Sandy Leon and two-run homer to Matt Skole in the eighth as Washington broke a 4-all tie with the offensive explosion.

lastname Mazzoni “We like his stuff. Today was a bad day,” Terry Collins said about Mazzoni, a second-round pick in 2011 from NC State, who went 5-3 with a 4.36 ERA in 13 appearances (12 starts) at Double-A Binghamton last season. “He was flying open. Stuff was flat. This kid has got very good velocity. He didn’t have it today. But he’s come with some high recommendations from the people in the organization that this kid can be an absolute late-in-the-game kind of bullpen guy, because he’s got three quality pitches. Today they just weren’t working.”

Jenrry Mejia’s own throwing error resulted in him allowing one unearned in two innings pitched.

Lefty relief prospect Adam Kolarek surrendered a leadoff homer to Ian Desmond in the third inning as the Nats grabbed a 2-0 lead.

After getting blanked for two innings by Gio Gonzalez, the Mets got on the board in the fourth inning against left-hander Matt Purke. Zach Lutz provided an RBI single that plated Wilmer Flores from second base, thanks in part to a weak throw from left field by ex-Met Scott Hairston. Anthony Seratelli followed that inning with a two-run single.

Jacob deGrom faced the minimum number of batters in two innings in relief for the Mets, working around a leadoff single in the fifth by coaxing a 6-4-3 double play from Steven Souza.

The Mets pushed the lead to 4-2 in the sixth on Taylor Teagarden’s sacrifice fly.

But in the seventh, John Church surrendered a game-tying two-run homer to Brian Goodwin. Then Mazzoni allowed seven runs in the eighth.

Lutz capped the scoring with a solo homer in the ninth.

What’s next: The Mets play three games Thursday … sort of.

In Kissimmee, Fla., the Mets have a 10 a.m. “B” Game against the Houston Astros. Logan Verrett, Jack Leathersich and Erik Goeddel are scheduled to pitch.

In the 1 p.m. Grapefruit League game there, John Lannan, Rafael Montero and Steven Matz now are due to pitch. Brad Peacock starts for the Astros.

Meanwhile, at 11 a.m. back at the Mets’ complex, a structured three-inning game takes place. Bartolo Colon (three innings), Jonathon Niese (two innings) and Bobby Parnell (one inning) all are scheduled to pitch.
