Once the calendar reaches May, athletes who compete in track and field know it is time to get focused.

They want to build toward the WPIAL championship May 13 at Slippery Rock University. The PIAA championships May 22 and 23 at Shippensburg University.

That starts Friday when many of the teams from around the WPIAL will compete in either the 52nd annual Baldwin Invitational or the Pine-Richland Invitational.

Baldwin has more than 62 teams entered. It will begin at 10 a.m.

Pine-Richland has more than 67 teams entered. It will begin at 10:30 a.m.

Franklin Regional junior Jamie Kociela, who has the top high jump in the state at 5-foot-8, is looking forward to the competition at Pine-Richland.

Her best jump occurred April 18 at the Butler Invitational.

“There are a lot of good jumpers in the WPIAL,” Kociela said. “I must continue to work hard. My goals are to be a WPIAL and PIAA champion. My next goal is 5-9.”

Franklin Regional coach Bob Ralston said he expects his teams to compete for titles, especially the boys, who lost 76-74 to Hempfield on Tuesday in the WPIAL semifinals.

“Our boys hope to compete for the team title,” Ralston said. “The main goal is to improve on their WPIAL standings. We are trying to get at least 30 kids to the WPIAL championship. We will try to better their marks and try to bring home a team title.”

The Cartwright twins — Sean and Ethan — are having fantastic seasons.

Sean Cartwright owns school records in the high jump, and the 110- and 300-meter hurdles. He broke Ethan’s record in the 110 hurdles at Hempfield. Both have run under 40 seconds.

“They go back-and-forth,” Ralston said. “Ethan broke the record first, and Sean then broke his in the next heat. They keep trading records and personal bests.”

Junior sprinter Loch Bresnahan was a double winner (100 and 200) at Hempfield.

“The Cartwrights and Loch are fun to watch,” Ralston said. “Jamie is a hard worker and is ranked first in the WPIAL.”

Some of the top teams at Pine-Richland include Butler, Freeport, Fort Cherry, Latrobe, Greensburg Salem, Greensburg Central Catholic, Grove City and McDowell.

Hempfield coach Ron Colland said he is eager to see how his teams compete.

“I was pleased how the girls performed in the semifinals,” Colland said. “We are going to take most of the kids. We are allowed three entries, and a lot of these kids worked hard.

“We are going to let them run certain events to save them for the WPIAL championship on May 5.

Hempfield is among the top teams at Baldwin. It is joined by Norwin, North Allegheny, Mount Lebanon, South Fayette, South Park and West Allegheny.

Baldwin features two extra races: the McKinny Mile and the Ed Helbig 2 Mile. They do not replace the 1,600- and 3,200-meter runs.

The running finals are slated to begin at 4:30 p.m.
