But in Saturday's rematch at the UNC Softball Complex, Bettker had a different number in mind: zero.
Bettker shut out the Tar Heels in ten innings of work, picking up a win and a save as the Terrapins swept a doubleheader, winning 3-0 and 5-1.
When UNC (30-25, 2-6 in the ACC) hosted Maryland on April 7, Bettker allowed seven earned runs on eight hits in six innings of work as the Tar Heels cruised to an easy win.
But the North Carolina bats managed just three hits in each game Saturday. Bettker threw a three-hit shutout in Game One and tossed three perfect innings of relief in Game Two.
"We didn't show up to play today," said UNC catcher Natalie Anter. "We didn't score runs; we didn't hit. We were there physically, but not mentally."
Anter was 0-for-3 with three walks and a pair of strikeouts on the day. The Terrapins (30-18, 2-3) were careful not to give her anything to hit, particularly because the games were tight.
The first game was scoreless until the top of the fifth, when Maryland's Jen Peel hit a two-run double to left-center field off Ashley Allen (13-7). Allen left the game in the bottom of the fifth after fracturing her left wrist sliding into second base. Her status for the rest of the season is questionable.
The Terps added an insurance run in the sixth, and Bettker made it hold up.
"We just didn't hit the ball," said UNC coach Donna Papa. "We didn't create a lot of opportunities for ourselves, which is uncharacteristic for us."
