"I was just praying it got through.
I saw the second baseman closing in on the ball and I was like, 'Keep going,' " said Delgado.
Prior to making his Sunday debut in Kansas City, Delgado had spent a significant portion of his professional career grinding through 710 minor-league appearances.

"It's still baseball, no matter where you play it," said Delgado.
He acknowledged the increased pressure that comes with playing at the highest level of professional baseball while remaining focused on producing results for his club.
"I know it's a lot of pressure. I know the guys are probably better and the lights are brighter.
But still got to get the job done any way you can," said Delgado.
The matchup initially featured an impressive pitching duel between former teammates Hunter Brown and Framber Valdez, who both allowed just a single run over six strong frames.
Detroit broke the deadlock in the top of the eighth inning when Hao-Yu Lee hit a double against Bryan King and subsequently crossed home plate on a sacrifice fly.
The Astros quickly answered in the bottom half of the frame after Yainer Diaz singled and Cam Smith reached safely on a fielding error by third baseman Kevin McGonigle.
Following a walk to Joey Loperfido that loaded the bases, Delgado delivered his hit, and Jeremy Peña later beat out a double-play ball to add an insurance run.
Josh Hader earned his third save of the year by closing out the ninth inning, giving up only a leadoff single to Riley Greene before retiring the next three Detroit hitters.
