CINCINNATI — It was Ryan Watson’s big-league debut with the Boston Red Sox, but longtime umpire CB Bucknor might have been feeling more pressure.

On a day that Bucknor, a member of a major-league umpiring crew since 1999, had eight calls challenged and a whopping six overturned, a sequence with Watson on the mound in the sixth inning was arguably the most egregious.

With the Red Sox trailing the Cincinnati Reds 5-3 in the sixth, Watson faced slugger Eugenio Suárez with the bases loaded.

Watson, a Rule 5 draftee whom the Red Sox acquired in December, got ahead 1-2 on Suárez before firing a borderline sinker that Bucknor called strike three. Suárez challenged. Seconds later, a scoreboard replay showed the pitch was just below the zone.

Suárez returned to the box and Watson to the mound, where he fired a four-seamer. Again, Bucknor rung up Suárez.

Suárez challenged a second time as the crowd roared in excitement, awaiting the video. Moments later, the replay showed yet another pitch just outside the zone, and the crowd went wild at two straight overturned calls.

Watson, who’d walked off the mound twice already, thinking he’d gotten his first big-league strikeout, remained poised in the pressure-packed spot.

On the seventh pitch of the at-bat, Suárez hit a grounder to second baseman Marcelo Mayer to get Watson out of the jam.

That outcome didn’t lessen the overall effect of Bucknor’s rough day. The Red Sox had lost their challenges early in the game with two missed calls, one on a challenge from catcher Carlos Narváez and another from Roman Anthony, but there were at least two other calls Boston could have challenged later in the game that Bucknor seemingly missed.

In the eighth, the frustrations with Bucknor mounted as Bucknor called out Trevor Story to end the inning on a check swing with runners on. The Red Sox had pulled within 5-4, and Story had a chance to break open the game, but couldn’t ask for a review. The typically mild-mannered Story screamed at the umpire and required manager Alex Cora and third-base coach José Flores to hold him back.

Cora remained on the field in a shouting match with Bucknor before the home-plate umpire eventually ejected him.
