Both the boys’ and girls’ team competitions at the 2013 Washington Catholic Athletic Conference championship came down to one race.

And for the boys, even that couldn’t truly decide things.

Trailing DeMatha by two points after 16 events, the McNamara boys won the 4x400 relay (3 minutes 28.60 seconds) Saturday by just 0.18 seconds over the Stags to force a 118-118 tie and earn a share of the two-day WCAC championship at Good Counsel.

Anchor Marcus Turner held off a determined charge by DeMatha’s Terry Gordon, saving a lead courtesy of Aaron Dillingham, Malik Self and David Thompson for the first title for McNamara.

“I didn’t want to let my teammates down,” Turner said. “That’s exactly what kept me going, knowing that everybody was relying on me, and I didn’t want to fail them.”

DeMatha’s Darryl Haraway was named the most valuable athlete for the boys with Maryland’s best time this season in the 200, setting a meet record (21.57 in the preliminaries) and eventually winning the finals in 21.88. He also won the 100 (10.77) and ran the second leg of the Stags’ first-place 4x100 (43.11).

“The 4x400, we had them by an inch or a millisecond,” Haraway said. “. . . But it feels good to have a co-championship, still first place.”

The Elizabeth Seton girls clinched their seventh consecutive WCAC title with a Herculean effort from the girls’ most valuable athlete, Maryland signee Taylor Tucker.

After winning the 100 and 300 hurdles (14.93 and 44.19) and running the second leg of the victorious 4x200 relay (1:41.36), Tucker thought her meet may be over.

But McNamara closed Seton’s lead to six points with a 4x100 relay victory (48.09) in the second-to-last event of the day, and the Roadrunners called on their star once more. She opened up a 5-meter advantage after the first lap, and Seton sailed to a 4x400 time of 3:54.27, finishing with 199 points to McNamara’s 191.

On a chilly, drizzly day, Tucker made some adjustments before her hurdling events to be ready. She finished just ahead of the Mustangs’ Danielle Wheatley (14.96 and 44.45) in both races.

“I tried to jog a lot more because of how cold it is and really work on snapping down my trail leg, and that helped me [those] last meters,” Tucker said. “I really hope I get MVP. That would be like a cherry on top.”

Her wish was granted.

An athlete from McNamara or Seton won nearly every individual girls’ event. The exceptions were Holy Cross’s Caroline Clark in the 800 (2:15.14) and Kiernan Keller in the 1600 and the 3200 (5:20.29 and 11:49.60).

Along with Seton’s Nina Crawford and T’Reyah Johnson placing 1-2 in the 400 (59.03 and 59.28, respectively), Javonne Antoine won the long jump (17-7.5), Jourdyn Beverly won the shot put (36-8.5) and Lenetta Mallory triumphed in the discus (107-03).

Jordan Martin starred again for the Mustangs boys, winning the 110 hurdles (14.34), long jump (22-3) and triple jump (43-4.5), while Kordell Williams cruised in the 300 hurdles (39.04) for the Stags.

Bishop O’Connell’s J.J. LaPointe won the 1600 (4:21.13) and 3200 (9:30.97) and finished as the runner-up in the 800 (1:58.77) to Good Counsel’s Collin Crilly (1:58.23).
