"I'm living the dream," Judge said. "I'm getting paid to play a kids' game, a game I've played since I was a little kid playing T-ball. I'm getting here with the New York Yankees, we're in first place, and I enjoy every day I come to the ballpark."

A three-time All-Star at shortstop in the National League, Castro is trying to earn his first AL selection at his new position. His 64 hits entering play on Wednesday are tied for second in the AL, and his .322 batting average ranks seventh in the league.
"I think it's a real honor," Castro said. "There's still a lot of games left before the All-Star Game comes, but I feel really happy that the fans support us. It's really emotional right now. Hopefully we keep playing like we're playing and the fans keep voting for us."
Judge enters play on Wednesday leading the Majors with 17 home runs, while pacing the AL with 39 runs scored. He has amassed nearly twice as many votes as third-place outfielder Mookie Betts (337,473), and is on pace to join Joe DiMaggio (1936) and Hideki Matsui (2003) as the only Yankees rookies to start a Midsummer Classic.
"This is just outside noise. I've got a job to do on the field," Judge said. "It's a great accomplishment, but like I said before, I've got a job to do on the field. That's where 100 percent of my focus is."
Other Yankees with notable showings at the first balloting checkpoint are Matt Holliday (276,855, third among AL designated hitters), Gary Sanchez (267,683, fourth among AL catchers), Didi Gregorius (239,170, fourth among AL shortstops), Chase Headley (174,702, fifth among AL third basemen), Brett Gardner (192,288, 11th among AL outfielders) and Jacoby Ellsbury (179,600, 12th among AL outfielders).
