With Greenwich Senior American Legion pitcher Dylan Callahan racking up strikeouts with his rising fastball and well placed curve, and Norwalk hurler Mark Ballard keeping the opposing batters at bay, it was apparent just one key hit was going to decide Tuesday's game.

It took a while, but Greenwich produced the clutch hit both teams were hoping for.

Shortstop Ricky Okazaki's RBI single in the top of the seventh inning propelled the Cannons past Norwalk 2-0 in a matchup with a playoff type feel to it at Greenwich Country Day School.

Right fielder Taylor Olmstead added a run-scoring single in the seventh for Greenwich, which saw the hard-throwing Callahan pitch a one-hitter with 13 strikeouts.

"Dylan has been a workhorse for us for years," Cannons coach Mike Abate said. "Any big game we have I know I could put him out there and get that type of performance out of him. It's really special to watch him work."

Norwalk got a similar type of effort from Ballard, who struck out six and scattered eight hits in 6 1/3 innings.

"Mark's a great pitcher with great determination on the mound," Norwalk coach Chris Brown said. "He deserved better today, but he just came out on the short end of the stick. That's what happens when you get only one hit."

Left fielder Zack Monick began the Cannon's seventh-inning rally with a lead off single. Callahan followed with a single through the left side, bringing up Okazaki, the No. 2 hitter. Okazaki went the other way with a fastball, lining a run-scoring single to right center field, giving Greenwich a 1-0 lead.

"I always have the same kind of approach at the plate that I've been working on every year," Okazaki said. "With a pitcher like that who pounds the strike zone you have to be aggressive. I just tried to make contact and it worked out for me. It felt great to do something good for the team."

Olmstead, who tripled in the first inning, scored Callahan with an RBI single to center field, putting the Cannons ahead 2-0.

"Ricky did a great job of getting a key base hit and working the count," said Olmstead, who was recently drafted by the Texas Rangers, but has elected to play baseball at UConn. "I tried to do the same thing and wound up getting a good pitch to hit."

Norwalk didn't go down easy in the bottom of the seventh inning, loading the bases when Alex Valenzano reached on an error, Sean Butler got hit by a pitch and Andrew Seiden drew a walk. But Callahan calmly worked out of the jam, striking out the final batter for the Cannons (13-2).

"In that situation, I was just trying to throw strikes and not leave anything over the plate," said Callahan, a right-hander. "I wanted to challenge them and try to make they hit it."

Callahan (4-0) had a similar approach the entire game. "I wanted to get ahead, throw strikes and the defense did a great job of picking me up the entire game."

Olmstead tripled in the first inning, but Ballard kept it a scoreless game. He then pitched out of a bases-loaded situation in the second inning.

"Whenever you play a team like Greenwich it feels like a playoff atmosphere," Brown said. "It's good competitive baseball and that's why you love it."

Second baseman Tyler Annunziata had the lone hit for Norwalk (12-8).

"I think we should be swinging the bats a lot better," Brown said. "We are good enough to where we should be scoring more runs."

Olmstead and Okazaki each had two hits for Greenwich, which will face Darien/New Canaan on Wednesday.

"We are playing great baseball right now," Abate said. "We're pitching, playing defense and getting timely hitting."
