The left-hander was going for his fifth no-hitter in a row that night, but Wrenn, the D-backs' Florida area scout, told Allison not to expect to see him do it.
"Listen, I just don't think he's going to throw the no-hitter today," Wrenn told Allison. "I think in the third inning there's a kid named Doty and he's a pretty good hitter for next year, he'll be the one to break it up."
Allison sat slack-jawed later that night when in the third inning Drew Doty lined a double over the right fielder's head to end Schuster's no-hit bid.
No-hitter or not, Schuster made an impression on the D-backs, who selected him in the 13th round of the 2009 First-Year Player Draft on Wednesday.
"We were happy to select the guys that we did today," Allison said. "It was a good day."
Here's a look at who was selected by the D-backs on Day 2:
Fourth round, David Nick, SS, Cypress (Calif.) HS: Advanced high school hitter. Has tremendous plate discipline. Will need to develop his power. Good instincts and baseball IQ. Could stay at short or play second.
Fifth round, Ryan Wheeler, 1B, Loyola Marymount: Put up very good numbers in the Cape Cod League last year. Can play the outfield. Attended a workout at Chase Field prior to the Draft and said his biggest thrill was hitting a homer into the pool beyond the wall in right-center.

|17||CF||Allen Pollock||U Notre Dame|

Sixth round, Bradin Hagens, RHP, Merced College: A converted shortstop. Has a good sinker and velocity.
Seventh round, Matthew Helm, 3B, Hamilton (Ariz.) HS: Local product who was a high-profile player coming into the year, but a pair of injuries caused him to miss time and so he slid a bit. Signed to go to the University of Arizona.
Eighth round, Paul Goldschmidt, 1B, Texas State Univ.: Southland Player of the Year, played last year in Alaskan League where he used a wood bat. Has tremendous power and controls the zone as well.
Ninth round, Robert Anderson, RHP, Univ. of Oklahoma: Threw in multiple roles for the Sooners. Moves the ball around well, fierce competitor. D-backs hoping for a quick sign.
10th round, Tyson Van Winkle, C, Gonzaga Univ.: Catch-and-throw skills are advanced. Bat lags behind, but the organization hopes with more at-bats in their system that part of his game will catch up.
11th round, Richard Allen, RHP, Lyman (Fla.) HS: A 17-year-old the team would like to get signed soon and out playing.
12th round, Charles Brewer, RHP, UCLA: Played high school ball in Scottsdale, Ariz., at Chaparral High School. Reliever Scott Schoeneweis spoke highly of Brewer to Allison.
13th round, Patrick Schuster, LHP J.W. Mitchell (Fla.) HS: He of the four straight no-hitters does not have outlandish signing demands, but has committed to the University of Florida. "He does want to explore the option of starting his pro career," Allison said. "We'll see where it goes. He's a fun kid to watch pitch."
14th round, Brett Greer, SS, Western Carolina Univ.: Good feel for the game.
15th round, David Narodowski, SS, Univ. of Kansas: Both Narodowski and Greer "just know how to play," Allison said.
16th round, Ryan Robowski, LHP Ohio Dominican Univ.
17th round, Andrew Wolcott, RHP, Duke University
18th round, Roidany Aguila, C, Puerto Rico: A high school kid, young athletic catcher. Took some leaps forward this year. D-backs would like to get him signed and into the system quickly.
19th round, Randall Hamrick, RHP, Brewton Parker College
20th round, Adam Worthington, RHP, Univ. Illinois-Chicago: "He's a senior who is one of those guys that is a really good competitor," Allison said. "We saw him pitch well against some really good competition."
21st round, Daniel Taylor, 21, LHP Univ. Central Michigan
22nd round, Evan Button, SS, Univ. of Mississippi
23rd round, Christopher Odegaard, RHP, Minnesota St. Univ.
24th round, Marshall Gemberling, RHP, Princeton Univ.
25th round, Taylor Wrenn, SS, Manatee J.C.: Scout Luke Wrenn's son. He completed his freshman year this past season. "We'll see how the summer plays out," Allison said. "He knows how to play shortstop and swings the bat from the left side. We'll follow him over the summer and see how it goes."
26 round, Daniel Kaczrowski, SS, Hamline Univ.
27th round, Willie Hale, RHP, Ohio State Univ.
28th round, Brian Budrow, RHP, Univ. of Utah
29th round, Jacob Williams, 1B, Brophy (Ariz.) Prep: Son of former D-backs slugger Matt Williams, Jacob has a scholarship offer to the University of San Diego. He is a switch-hitter who is fluid around first base. "He did a terrific job this year of establishing himself as a Major League prospect," Allison said.
30th round, Jack Marder, SS, Newbury Park (Calif.) HS
