KETCHUM — Rain has forced the postponement of Thursday’s games in a Class 2A baseball regional here.

Officials pushed the start back one hour, then two hours and finally opted to delay the start of play until Friday, May 4.

The schedule finds Ketchum (25-5) facing Oklahoma Union (9-14) in the 11 a.m. opener followed by Wyandotte (19-11) and Quapaw (12-11) at 1 p.m.

The first-round winners square off at 3 p.m. with the losers playing at 5 p.m.

An elimination game will be at 4 p.m. Saturday, followed by the championship game at 6 p.m.

Time of an “if necessary” game Monday will be announced.

Teams in the regional are familiar with each other.

Ketchum defeated Oklahoma Union 8-4 on March 17 and owns 9-2 and 8-1 wins over Wyandotte in the Lucky 7 finals and April 17, respectively.

Its game with Quapaw on March 9 was cancelled.

Wyandotte is 2-1 against Quapaw (winning 9-5 on March 12, losing 4-2 in the Mickey Mantle Classic and winning 8-0 on April 19) and nipped OU 1-0 on April 21.

Both Wyandotte and Ketchum qualified for the 2A state tournament a year ago.

The Bears nipped Panama 5-4 in the finals of their regional but suffered a 4-1 loss to Silo in the first round of state.

Ketchum crushed Mounds 14-1 in the regional final but dropped an 11-6 first-round decision to Oktaha Wyandotte and Ketchum were the only spring-only team in the field. Silo, Oktaha and the other four teams also play fall baseball.

This will be Quapaw’s first regional appearance since 2014 — when it was eliminated by Oklahoma Union.

The Cougars are making their fourth straight trip to the regionals.
