Callahan retired after the Indians' district championship a season ago, but returned to fill the void when successor Chris Zimmerman was hired to replace long-time boys coach Joe Klebon.
Neither team pleased its coach early in Monday's game. More than 2 1/2 minutes elapsed before the first point was scored. It was 6-all at the end of the first quarter as the teams combined to shoot 3-of-22 and commit 13 turnovers.
Then, after Kelleher made two fouls to open the second period, Lewisburg gave it away on five straight trips and Shamokin surged ahead. The Dragons, missing senior post Lois Lesher to early foul trouble, surrendered four offensive rebounds (and, eventually, a putback) on one Shamokin possession.
"With all those turnovers, I just really wanted to step up," said Kelleher. "I wanted to make my way (in the offense) and see where I could fit in to get some shots."
Kelleher broke Lewisburg's slump with a pull-up 12-footer and, minutes later, canned consecutive treys for a 16-12 lead. She then drained four straight fouls and, closed the half with a steal and transition bucket for good measure.
"Maria came up big," said Stamm. "We were struggling offensively in the first half, and I told the girls it's our first game and I didn't really expect us to come out and execute everything that well. But Maria really picked us up."
The Dragons' lead grew to 28-18 as Lesher scored four of her 10 points in the first three minutes of the second half.
Shamokin, however, began to exploit the size/athleticism mismatches of senior Kelsey Yacko and junior Olivia Bonshock. The forwards combined for 13 third-quarter points. Bonshock hit a 3-pointer late in the quarter, then went inside for a free throw and a putback to cut it to 33-30.
