All-star season for the state’s top high school athletes continues to grow each year, and the baseball world is no exception.

Three games are scheduled over the next four days featuring Maine’s top high school seniors as well as the best up-and-coming underclassmen.

The weekend’s slate begins Friday with the state’s original baseball all-star contest, the 15th annual Maine Senior All-Star Baseball Classic beginning at 7 p.m. at Mahaney Diamond in Orono.

The game features East and West rosters that involve 49 of the top senior players, including what are now the five finalists for the annual Mr. Baseball award.

Collin Henry of George Stevens of Blue Hill, Ian Lee of Hampden Academy, Joey Martin of Portland and Mark Schmidt of Gorham were announced as four finalists earlier this week, but inadvertently left off that original list sent to the media by event organizers was pitcher-outfielder Joe Fessenden of Portland.

Fessenden hit .429 during the regular season with a .571 on-base percentage and a .786 slugging percentage to go with two home runs and 16 RBIs.

The right-hander also went 7-0 overall on the mound, including 5-0 with a 1.25 earned run average during the regular season. He went 2-0 during postseason play, pitching a five-hitter in a 4-1 win over Sanford in the Western Maine Class A quarterfinals and working the first five innings of the Bulldogs? 7-3 victory over Gorham in the regional final.

One of those five finalists will be presented the Dr. John Winkin Award as the 2006 Mr. Baseball during ceremonies just before the opening pitch of the all-star game.

Henry and Lee will lead a 25-player East contingent that includes 12 Class A representatives, seven players from Class B, four Class C players and two representatives from Class D.

The 24-player West squad, led by Fessenden, Martin and Schmidt, features 12 Class A players, seven from Class B and five from Class C.

The West won last year’s game 11-2 behind two hits, two runs scored and three RBIs from 2005 Mr. Baseball Ryan Flaherty, a shortstop from Deering of Portland.

Forty of the state’s top younger players will get to play on the big stage at Hadlock Field in Portland on Sunday in the Frozen Ropes Maine Underclassmen All-Star Game.

The game will feature 20-player East and West rosters doing battle immediately after the 1 p.m. Eastern League game between the Portland Sea Dogs and the New Hampshire Fisher Cats.

Then on Monday comes a new entry on the high school baseball all-star schedule, the inaugural Maine-New Hampshire Senior All-Star Game set for a 1 p.m. start at Merchantsauto.com Stadium in Manchester, N.H., home of the Fisher Cats.

Maine and New Hampshire will each field an 18-player roster, with Maine’s contingent including Henry, Lee, Cory Smith of Ellsworth, Blake Wessel of George Stevens, Mike LaCasse of Skowhegan and Justin Willey of Messalonskee of Oakland.

This game was the brainchild of Mike Coutts, owner of the Frozen Ropes Training Center in Maine, and Tom Underwood and B.J. Neverett of the New Hampshire Baseball Coaches Association. The game is sponsored by ProNine Sports, Frozen Ropes and the baseball coaches associations of Maine and New Hampshire.

This Maine-New Hampshire game will alternate on an annual basis between Manchester, N.H., and Hadlock Field in Portland.
