"It was good to get up to almost six innings," said Hahn of his last outing. "It's good to build my stamina up, and each start I feel like I get stronger and stronger."
Hahn struggled against Pittsburgh, but found the team's decision to bring him back up more of a confidence boost than having a small amount of Major League experience.
"I think it doesn't change anything," he said. "You still have to go down there and pitch your game. If you throw the ball up, then hitters down there are going to hit it, too. It also builds confidence for me knowing that they gave me another shot to come back up here. Obviously, they saw something they liked."
"Our front office, and our Minor League people felt this is a decision they think was the right one to make with Jesse," said manager Bud Black. "Jesse threw the ball well [in San Antonio] his last outing. The first time in San Diego I think he ran out of gas. Here we are 10 days later. We think he's built up a little more for this game."
His debut was at home in a familiar environment, but none of his Connecticut-based family could see him pitch in person. Saturday at Citi Field will be different.
"I think I got the first one out of the way," said Hahn, who will square off with Mets righty Zack Wheeler. "I'm going to be relaxed. I'm only 45 minutes to an hour away from home, so I have a lot of family here, I have a lot of support."
"It can help and hurt," said Black about having family in attendance. "On balance, it's more helpful. Family, friends, I think can add a lot of ease."
