Vazquez was struck in the right index finger while trying to lay down a seventh-inning sacrifice bunt in the Yankees' 2-1 victory over the Mets, leaving the game soon after.
Though the Yankees feared the worst when Vazquez peeled off his bloody batting gloves in the dugout, X-rays came back negative, and the right-hander was relieved to learn that he had only bruised the finger.
"It's frustrating a little bit, but the good news is that the finger is good and the X-rays are negative," Vazquez said. "I'm pretty sure I'm going to make my next start."
The injury took place on the first bunt attempt Vazquez made that inning against pitcher Elmer Dessens, which rolled foul. Vazquez got another one down, advancing Kevin Russo to third base, but he felt pain in the finger when he jogged down the baseline.
"I feel so embarrassed," Vazquez said. "I've been doing this for a lot of years in the National League, and this never happened to me. I just grabbed the finger near the barrel, toward the skinny part of the bat, and the ball just hit me."
After the play, Vazquez was seen in the visitors' dugout receiving attention from head athletic trainer Gene Monahan and assistant athletic trainer Steve Donohue. As Vazquez retreated to the clubhouse, Donohue was holding one of Vazquez's fingers.
The right-hander was working on a one-hitter and had thrown 70 pitches (46 for strikes) in his sharpest start of the season, having walked two and struck out six.
Yankees manager Joe Girardi said he was hopeful that Vazquez would be able to make his next start, which is scheduled for Thursday against the Twins at Target Field. Girardi said that the Yankees would probably know more by Sunday.
"I'm hopeful that he's going to be able to make his next start," Girardi said. "I'll be frustrated for him if he can't make his next start. It's something we'll have to deal with. The good thing is that it's not broken, and that's a big plus for us."
