The growth of the Prospect League will be on display Wednesday at Pullman Park.

The fifth-year summer collegiate baseball league brings its All-Star Game to Butler in front of what is likely to be a standing-room only crowd.

“Our league had 50 players — current or past — selected in the (MLB) amateur draft last month,” Prospect League Commissioner Dave Chase said. “The most players we had selected in any previous year was 25.

“Our goal when we put this league together was to become one of the best summer collegiate leagues in the country. Right now, we’re definitely among the top three.”

The All-Star Game has been well-attended and well-scouted in the past. This year appears to be no exception.

“Reserved seats are sold out, but some are being held for family members of out-of-town players and may be put back on sale if those families don’t come,” Butler BlueSox general manager Patrick Reddick said.

As of Friday, approximately 200 seats remained for the game, which begins at 7 p.m.

“We are getting significant calls from out-of-towners inquiring about tickets,” said William “Wink” Robinson of the BlueSox ownership group. “We encourage fans intending to come to the game to buy their tickets ahead of time.”

Seating capacity at Pullman Park is 1,450 and standing room tickets will be sold.

“When the fire chief says no more, we’ll have to close the door. We don’t want to turn our fans away,” Robinson said.

Prior to the All-Star Game, an 11:30 a.m. luncheon for the 60 players, along with coaches and managers involved in the game, will be held at the Marriott Pittsburgh North. Players will participate in a pro scout workout at 3 p.m. at Pullman Park, followed by a home run derby at 5 p.m.

“You never know how many scouts will turn out, but there is no major league baseball that night and we anticipate quite a few showing up,” Chase said.

“The Class AAA and Frontier League All-Star Games are being played the same night, but scouts tend to favor our game because the players are younger.”

Gates will open at 2:30 p.m. and ticket holders will be permitted to come and go as they please during all of the all-star events.

The game itself will feature seven .300 hitters in the respective starting lineups and six pitchers with earned run averages below 1.50. The league has 12 pitchers with ERAs under 2.00 right now.

“Pitching has been outstanding throughout the league this year,” said BlueSox manager Anthony Rebyanski, who will manage the East Division all-star squad. “It’s been dominant more often than not.

“We (BlueSox) hit more than 20 home runs last year and we’ve got five this year. Home runs are down throughout the league. Still, it’s an all-star game and the best hitters will be here, too. Those guys may put on a show.”

The game will feature the Prospect League’s leading hitter — West Virginia’s Kaeo Aliviado at .378 — along with home run leader Dan Zuchowski (5) of Chillicothe and RBI leader Zach Ratliff (32) of Lorain County.

BlueSox players in the game include Adam Aldred (1.13 ERA), Russell Clark, Tyler Ferguson, Ryan Fitzgerald, Matt Peters (.360 batting average) and Taylor Schmidt.

The Slippery Rock Sliders will be represented by Kevin Becker-Menditto (8 saves), Matthew Calhoun (.333, 4 HR), Zach Strecker and Storm Wilson (.320).

Home Run Derby participants will be selected by Rebyanski and Quincy manager Chris Martin, who will be guiding the West Division stars. Balls hitting the fence will be worth one point, balls clearing the fence two points.

Metal collegiate bats will be permitted for five of each batter’s 10 swings in the finals “to add some spice to the derby,” Robinson said.

A Zambelli fireworks show will follow the game and “will be twice the display of what we normally do on Fireworks Night,” Robinson added.
