Errors can cost games.

The Oakville junior varsity American Legion baseball club found that out last Saturday as it dropped a 12-5 decision on the road to Rock Memorial.

“We just didn’t play very well,” head coach Matt Boyer told the Call. “In the first few innings, we got behind with a few mental and physical errors. We just didn’t get anything going.”

Oakville (11-3) starting pitcher Tim Kappel took the loss as he gave up nine hits in five innings pitched. Kappel gave up six earned runs and retired five batters via strikeout in the loss.

“Tim’s first game pitched this season was against Ballwin and he threw a complete game with 106 pitches,” Boyer said.

“What’s hard on him was that we made mistakes and didn’t come to play defensively. It’s not that he threw any worse than he did against Ballwin.”

Right fielder Louie Haseltine batted in the designated hitter’s slot while nursing a sore quadricep.

Despite the injury, Haseltine is batting a solid .419 with six doubles and 11 runs batted in.

“Louie’s been hitting the ball really hard,” Boyer said. “Right now, he’s been nursing a sore leg and has been batting as the D.H.”

Oakville rebounded from its loss later in the day with their second win of the season over Lemay in a 6-0 hammering of Post 162.

“We came out ready to play and this was the second time we’ve beaten (them) this year,” Boyer said.

“We swung the bats aggressively and actually looked like a completely different team.”

Grabbing the win on the mound was starting pitcher Joel Claeysk, who threw a complete game of seven innings with one hit and nine strikeouts.

“Two of his rotations this season have come against Lemay,” Boyer said. “His first outing came against Creve Coeur and he struggled the first couple of innings.”

Center fielder Adam Boyer was two for three at the plate with a triple and a single. Boyer currently is batting .441 with nine runs batted in.

“Adam’s been hitting the ball,” Boyer said. “He’s been our leadoff hitting and usually gets the job done for us.”

Oakville travels to Hillsboro today — June 17 — for a non-league friendly against Post 783.

“We beat them 10-0 earlier in the year,” Boyer said.

“In that game, we swung the bats really well against them. They (Hillsboro) do have some good ballplayers out there and should have a decent team.”

The Hillsboro game is scheduled for a 5:45 p.m. start.
