Jen Pawol breaks MLB's gender barrier as 1st female umpire to work regular-season game

Jen Pawol has made history as the first female umpire to work a regular-season game in the major leagues.

Pawol's much-anticipated debut came as the first base umpire for Saturday's first game of a split doubleheader between Atlanta and visiting Miami. She enjoyed a quiet first inning, watching as Atlanta right-hander Hurston Waldrep struck out the first two batters before Agustin Ramirez lined out to third baseman Nacho Alvarez.

Atlanta was set down in order by Miami right-hander Ryan Gusto in the bottom of the first inning, with no calls from Pawol needed at first base.

As the first base umpire, Pawol's responsibility was to check Waldrep's hands for foreign substances following the inning. During that brief encounter she also appeared to receive a warm greeting from Atlanta catcher Sean Murphy on his way to the dugout.

Pawol's first real test came in the third inning when she called Murphy safe on a close play. Replays indicated Murphy may have been out, but Marlins manager Clayton McCullough did not challenge the call.

Pawol also showed she will make animated calls. When Miami's Xavier Edwards grounded into a double play, Pawol pumped her fist and lifted her leg when she called Edwards out in the third inning.

Pawol couldn't help but notice her debut was being watched closely. Fans responded with a warm ovation when the video board focused on the umpire between innings, forcing her to take a quick glance at her image.

Pawol will work third base in Saturday night's second game of the
