Two teams seemingly headed in opposite directions abruptly changed courses again when third-ranked Boys’ Latin School dominated the second half of a thorough 13-9 victory over No. 5 St. Mary’s on Tuesday afternoon in a MIAA A Conference lacrosse contest at soggy Pascal Field in Annapolis.

The Lakers, who barely eked out a win over Mount St. Joseph on Friday, came into the game looking for a way to unleash their offense after struggling a bit against the Gaels.

Conversely, the Saints were riding high after knocking off then-No. 4 St. Paul’s School last week, and were looking to claim their third consecutive win to open MIAA A play.

And in the first half, St. Mary’s continued to play at a high level while Boys’ Latin looked flat.

That dynamic changed drastically in the second half behind an offense that had plenty of opportunities because of senior Jake Glatz’s superior work at the face-off X.

After losing the first three draws to St. Mary’s junior Tucker Booth, Glatz went to work.

The 5-foot-11, 200-pound Penn State recruit traded face-off wins with Booth before reeling off 11 in a row as the Lakers (9-3 overall, 3-0 MIAA A) surged into the lead.

“I was cold at first, and he’s a really good face-off guy,” said Glatz, who grabbed 17-of-25 draws in the contest. “And the long bus ride may have had something to do with it, too. But then (face-off) coach Tano (Arrogancia) calmed me down at halftime, and I started winning them.”

The other key, beside a much more aggressive offense, was junior goalie Chris Brandau. He turned away five shots in the third quarter when the Lakers went from a 5-3 halftime deficit to an 8-6 advantage. Brandau finished with a dozen saves.

“BL came out with more intensity in the second half,” St. Mary’s coach Victor Lilly said. “We had a 5-3 lead at the half and then we took a step back. It just took us to long to adjust to them, and we played way too much defense in the second half.”

Senior midfielder Koby Russell put BL on top with just over nine minutes remaining in the first quarter before the Saints (11-2, 2-1 MIAA A) took the lead on consecutive goals by junior attackman Taylor Bohanan.

The Lakers tied it late in the period when freshman attackman Brendan Grimes alertly punched in a rebound after a save by junior goalie Aleric Fyock.

Garrett Nilsen broke the tie for St. Mary’s on a spinning move through several longsticks and fellow sophomore attackman Ian Krampf doubled the advantage on an unassisted goal with just under seven minutes left in the half.

Junior attackman Matt Brandau and Bohanan then traded goals as St. Mary’s entered the intermission in pretty good shape.

“We thought the guys were a little tight, like they were against St. Joe,” Said BL coach Brian Farrell. “They needed to loosen up a little.”

Russell inched the Lakers a little closer with a goal before Brandau netted the equalizer a couple of minutes later.

Bohanan’s fourth goal gave the Saints their last lead which preceded a pivotal 5-0 run by the Lakers that bridged the third and fourth quarters on two goals each by senior attackman Luke Shilling and Grimes and one by Russell for a 10-6 cushion with eight minutes left in regulation.

At that point, with Glatz controlling the draws and BL getting stops from Chris Brandau, it was only a matter of time before the Lakers prevailed.

“They were making us take shots from where they wanted us to take them,” Lilly said. “Their goalie did a good job and they won a lot of face-offs until we got a couple of them. The good news in this league is, whether you win or lose, you have another chance in the next game.”

Each team notched three goals in the late going, including BL’s Greg Ey and St. Mary’s Tristan Michie joining in the fun.

The Lakers now are tied at the top of the A Conference standings with No. 1 Calvert Hall, which beat Archbishop Spalding, 14-7, on Tuesday.

BL hosts No. 2 McDonogh on Friday while the Saints travel to Towson for a night game against the Cardinals.
