NEW YORK -- There was good news and bad news for the Reds on Tuesday night at Citi Field. The good news was that right-hander Luis Castillo showed why he is the ace of the Reds’ pitching staff this season. He was solid for 6 2/3 innings and struck out seven batters, all with a large contingent of family members cheering him on from behind the visiting team’s dugout.

The bad news was that Castillo ended up with his third no-decision, as the Reds lost the game in 10 innings, 4-3, on a sacrifice fly by the Mets’ Pete Alonso.

It meant a lot to Castillo to have his family, including his wife and brother, in the stands to support him. There were at least 20 family members sitting in the box seats near third base. Never once did Castillo feel nervous because his relatives were on hand.

“It was a normal game. I just went out there and had fun. There was no pressure at all,” Castillo said through interpreter Julio Morillo.

Castillo cruised through the first six innings while the Reds were deadlocked in a 1-1 tie. But the seventh inning came and Castillo allowed the go-ahead run. Todd Frazier swung at a first-pitch fastball and hit the ball over the left-center-field fence to give New York a one-run lead.

“It was the first pitch of the inning,” Castillo said. “It caught too much plate and he put a good swing on the ball and he hit the homer.”

Reds manager David Bell felt Castillo had his best outing of the season. The way he was going, Bell felt, the Reds’ ace could have completed the game.

“The changeup looked like it was falling from the table,” Bell said. “He had a really good fastball. He had good stuff quite a few times, but I thought from the side he was at his best [today]. He was just pitching with confidence.”

Castillo agreed with Bell’s assessment of his outing.

“I was attacking the zone,” he said. “I was attacking the hitters. I was commanding my pitches tonight. Everything was good tonight.”

The Reds rallied to tie the game in the ninth before Raisel Iglesias, who had pitched two innings on Monday night, allowed two hits and the sac fly to Alonso in the 10th.

“We’ve done a good job of battling back and staying in games,” Bell said. “That would have been a great one to win because of the effort to tie.”
