Three Western Maine baseball semifinals will be played today after they were rained out Saturday.

In Class A, top-ranked Cheverus (15-2) hosts No. 5 South Portland (11-6) and No. 2 Westbrook (15-2) will be at home against No. 6 Marshwood (12-5). Both games start at 4 p.m.

The winners meet for the regional title at 3 p.m. Wednesday at St. Joseph’s College.

In Class B, No. 1 Yarmouth (14-3) hosts No. 4 Lincoln Academy (13-4), also at 4 p.m.

In the other Class B semifinal, No. 2 Greely (15-3) beat No. 6 Falmouth 8-3 on Saturday to advance to Tuesday’s regional final at 3 p.m. at St. Joseph’s College.

Greely and Falmouth had a 1 p.m. start, which enabled them to play their game, although it rained throughout.

The other regional semifinals had 3 p.m. starts. It had been raining for several hours by then, so the games were postponed.

“We would have rather played Saturday, but there’s nothing you can do about the weather,” said Cheverus Coach Mac McKew.

“It kind of sums up the whole season. We had to deal with rain toward the end of the season and now in the playoffs.”

Looking on the positive side, McKew said Saturday’s postponement gave his catcher, Nic Lops, some time off, and now Harry Ridge, who pitched Friday against Thornton Academy, could be used for an inning today if needed.

“Lops has caught every game, so he could use some time off,” said McKew.

AT THE GREELY and Falmouth game, both head coaches had their fathers in the dugout. Greely’s Derek Soule had his dad, Mort, alongside, as did Falmouth’s Kevin Winship with his dad, Gary.

The rain picked up in intensity as the game progressed, but it never poured, which was a good thing. Once the action started, there was no stopping it, as the teams wanted to finish.

Despite the conditions, there were only four errors, two by each team.

THE CLASS A tennis state championship — for both boys and girls — pitted a traditional powerhouse, Lewiston, against upstart Scarborough, whose boys’ and girls’ teams were both making their first appearance beyond the regional finals.

The occasion also brought together longtime doubles partners from the Maine Tennis Association circuit: Ron Chicoine, who coaches at both Lewiston High and the University of Southern Maine, and his regular partner, Steve Eddy, a Scarborough assistant who works mainly with the girls’ team.

“I don’t like coaching against Steve, because he knows how I coach,” Chicoine admitted. “This team is well coached. They play good fundamentals.”

Chicoine was particularly impressed with Scarborough’s No. 1 boys’ doubles team of junior Joe Corbeau and sophomore Jeff Sirocki, who extended Chicoine’s nephews, Alex and Ben Chicoine, before falling 6-4, 7-6 (6).

“We just executed a little better on the key points,” Chicoine said. “But it was good tennis.”

WAYNFLETE COACH Linda Cohen brushed away tears as she congratulated her girls on rising from the eighth seed in the West to the Class C state title, overcoming early-season injuries to senior Maddie High and freshman Emily White (who had never played competitive tennis before this season).

This was Cohen’s fourth season at the helm, and High has been with her all four years. There was another reason for Saturday’s emotions, Cohen said.

She had been quite close to her own high school tennis coach, Sandra Seidel of Bethlehem, Pa., who died in September.

“She was a great mentor and a great coach,” Cohen said, “and I’m sure she was watching over me (Saturday).”

WAYNFLETE SENIOR Brandon Thompson, the 2010 state singles champion, opted to run outdoor track this spring, but he was on hand Saturday at Colby College to cheer for his former teammates and his younger sister, Kaitlynn, who led a singles sweep in a 4-1 victory over George Stevens Academy.

Thompson wasn’t without a racket this spring. He and classmate Eric Ordway, who played No. 2 singles this spring and earned the critical point with a decisive third-set tiebreaker in a 3-2 regional semifinal victory at Winslow, joined forces for a Senior Project that involved more than 80 hours of free tennis lessons.

Thompson and Ordway went through a weekend of training to become certified as associate tennis instructors. They proceeded to give group and individual lessons to other Waynflete students, some on the tennis team, but others who play baseball and lacrosse, row crew and run track.

Olivia Chap, a senior lacrosse player, had never picked up a racket. Her Senior Project involved learning to play tennis, and by the end Ordway said she could have played on the varsity team.

“We didn’t actually have a day off,” Ordway said. “We worked six hours Saturdays and Sundays. On weekdays we had bigger group lessons.”

An instructor undergoing training at the same time even offered the Waynflete seniors a job at his camp in Connecticut.

“It was interesting,” Ordway said, “after learning tennis, to get out and share some of my experiences.”
