The Saguaros extended their early lead to 2-0 in the fourth, when former first-round pick Christian Colon, the Royals' No. 4 prospect, sent a 3-1 fastball from Nick Schmidt (Padres) over the left-field fence. It was his first Arizona Fall League long ball.
In the sixth, Mets prospect Juan Lagares singled home the tying run before a base hit by Jaff Decker (Padres) put Peoria in front. Hagerty came to the plate with the bases full and one out, sending a first-pitch changeup from Royals right-hander Bryan Paukovits (0-1) into center field for a three-run double.
"I was loooking for something out over the plate," said Hagerty, who also singled in the third and fifth. "It was nice to give the club some breathing room."
Hagerty was just 2-for-21 (.095) in his first five AFL games. This was his first game since Wednesday as the Javelinas carry three catchers.
"I have been struggling a little bit, trying to do too much, so I was happy with the outcome," he said. "It's pretty tough for all three of us, not getting at-bats. ... When I do play, I got to take advantage of it."
A 2009 fifth-round Draft pick, Hagerty is the Padres' No. 9 prospect after batting .284 with 43 extra-base hits and 65 RBIs in 104 games between Class A Advanced Lake Elsinore and Double-A San Antonio.
"I felt pretty good in high-A, where I was playing every day," said Hagerty, who won a Texas League championship with San Antonio. "Double-A was tough. It was an adjustment and I made some mistakes, but I learned from it. It was a good experience seeing that pitching and knowing the approach I'll have to have against those guys."
Lagares also singled home two runs in the Javelinas' three-run ninth to complete a 3-for-5, four-RBI game.
Surprise starter Sean Gilmartin was denied his third straight victory. The Braves' first-round pick in June allowed one run on four hits over five innings, walking one, striking out four and throwing 63 pitches.
