Prospect Heaney has handled Triple-A hitters

WASHINGTON -- The Marlins really want to be patient with their top prospect Andrew Heaney.

But the way Heaney is throwing, he appears to be in a hurry to reach the big leagues.

On Tuesday night, the lefty made his second start for Triple-A New Orleans, and it was impressive. He struck out seven and allowed one hit in six scoreless innings against Round Rock.

The lone hit was a single by Bryan Petersen, the former Miami outfielder.

Only rain slowed Heaney down, as the game was halted after Heaney threw a couple of pitches in the bottom of the seventh inning. New Orleans won, 9-0.

Heaney is 1-0 with a 0.82 ERA and 14 strikeouts in 11 innings in two Triple-A starts. Counting his Double-A Jacksonville numbers, the lefty is 5-2 with a 2.09 ERA and 66 strikeouts in 64 2/3 innings.

"I hear nothing but good things about him," Marlins manager Mike Redmond said. "About him throwing strikes and pounding the strike zone, and the way he pitches. Believe me, we all see the same things that you guys do, and we're all checking on all our Minor League guys."

The Super Two deadline is around June 4, and Heaney will not be promoted before then.

At the time Heaney was moved up to Triple-A, the thought was he'd get at least four or five starts at New Orleans. The key is to make sure the lefty, who turns 23 on June 5, is ready.

"When his day comes, when the organization decides it's time for him, then it would be great to have him and see what he can do," Redmond said.

If Heaney stays pitching every five days, he conceivably could join the Marlins around June 6 when the team is at the Chicago Cubs. If he stays at New Orleans, then the club could decide if they want him to throw at Texas on June 11 or wait a couple of days to have him debut at Marlins Park during the Pirates' series, which is June 13-15.

"He's got great stuff," Redmond said. "I think it's good competition in Triple-A to kind of see where he's at, and obviously he's handled it really well. That's a good sign. When that day comes for him, I think the most important thing for us is to make sure that when that day comes that he's ready for it."

Cishek making a case for NL All-Star squad

WASHINGTON -- Pitching for Team USA in the 2013 World Baseball Classic was about as high an honor Steve Cishek thought he could receive.

Aside from pitching in the World Series, Cishek couldn't imagine a bigger thrill being on the mound.

The way the Marlins' closer is throwing right now, he is making a case to be a National League All-Star for the first time. Cishek is 11 of 12 in save chances entering Wednesday, and he has a 4-1 record with a 1.74 ERA. He's struck out 26 with six walks in 20 2/3 innings.

Fans don't vote for the All-Star pitchers. Those who decide pitchers have something to think about with Cishek.

"If it happens, it happens," Cishek said. "If it doesn't, it doesn't. Move on. But it would be cool. It would be an honor of course. But I'm not even thinking about it."

Cishek has already experienced the thrill of the World Baseball Classic.

"Yeah, I figured that was probably the closest I'd come," he said, to being part of an All-Star environment. "That was an incredible experience. I don't know if anything other than the World Series or playoffs in general would compare to that."

Cishek's velocity has been increasing of late. According to Fangraphs.com, the sidearm-throwing right-hander is averaging 92.6 mph on his fastball. Earlier in the season, it was in the 90-mph range.

Because of his arm angle and his lanky frame, that 93-94 mph fastball looks like 98 mph from someone throwing more over the top.

Cishek noted that he dealt with a stiff neck in Spring Training, which threw his mechanics off a bit.

"I just got into some bad habits," he said. "I was throwing the ball differently."

Marlins await word on makeup game

WASHINGTON -- No definitive date has been set for when the Marlins will make up Tuesday's rained-out game against the Nationals.

Manager Mike Redmond said he was informed it will be sometime during the final series of the season, Miami's last visit to Washington.

Indications are it will be either Friday, Sept. 26, or Saturday, Sept. 27, as part of a day-night doubleheader.

What the Marlins do know is the game on Tuesday night was called pretty early. The Nationals announced the postponement around 7:15 p.m. ET. But about an hour later, the rain had stopped, and the tarp was off the field. It didn't rain the rest of the night.

"I think it seemed early to call it," Redmond said. "But that's their call and there's not a whole lot we can do about it, just be ready to play [Wednesday]."

The home team makes the call on when the game starts. Once it does, then the game falls under the jurisdiction of the umpires.

Redmond joked that he had a nice walk around town on Tuesday night.

"I did," he said. "I didn't even need an umbrella."

The Nationals right now have several regulars on the disabled list, including Bryce Harper and Ryan Zimmerman. And the starting pitcher set for Tuesday was Blake Treinen, who was filling in for Gio Gonzalez, who is on the disabled list.

Miami had to reshuffle its rotation due to the rainout. Henderson Alvarez was set to start on Tuesday, and he was pushed back to Wednesday. Jordan Zimmermann, meanwhile, remained on schedule to throw, while Treinen has now been skipped.

"It was nasty at the time they made a decision, and that's it," Redmond said. "We'll play when they tell us to play, that's all we can do."
