Sheehan senior catcher Mark Brennan made his senior debut Thursday in the Titans 16-6 win over Hillhouse.

Brennan, who missed Sheehan’s first three games with a hand injury, went 1-for-3 with a triple against the Academics. The Titans also beat Hamden 6-3 Friday with Brennan behind the dish.

“I expect him to be the same guy,” Sheehan coach Matt Altieri said. “He knows what he has to do. He’s got a good head and bat at the plate.”

The Marist-bound Brennan finished with seven home runs and 12 RBIs last season for the Titans, who won the Class L state title.
