It’s not at all uncommon for the final three columns of a baseball scoreboard to have columns labeled R, H and E.

Without knowing what the columns stand for, it can be hard to determine just what the method to the madness means.

The values in each box will never go down, but an increase in one does not always mean an increase in another.

The R stands for runs – the thing that matters most.

Redshirt senior right fielder Payton Brennan’s two-RBI, seventh-inning single put No. 1 UCLA baseball (19-2, 7-0 Big Ten) up 12-2 over Maryland (11-10, 1-3) – with the 10-run differential igniting Friday’s series-opening run-rule walk-off at Jackie Robinson Stadium.

Though the Bruins’ H column ended at 12, just like their run total, the Terrapins’ had a figure of nine – seven more than runs scored.

Why the difference?

Junior right-hander Logan Reddemann.

“Maryland can really hit,” said coach John Savage. “He (Reddemann) had to work for every out. … There’s a lot of baseball left this weekend. And you know, he gave us 105 pitches through six innings and he competed his butt off.”

Despite surrendering eight of Maryland’s nine hits, Reddemann limited the damage to just a pair of runs – stranding six.

The right-hander used his defense – with junior third baseman Roman Martin both starting a second-inning double play and ending the sixth by diving into third for an unassisted force out.

But that’s not to overlook Reddemann’s seven strikeouts.

Two came back-to-back to end the third and strand a Terrapin on second – while another ended the fifth and left a runner on first.

“He’s awesome to catch and awesome to play with,” said junior catcher Cashel Dugger. “Having conviction with what you’re doing is one of his strengths, and that’s especially what he did tonight. Maryland didn’t give away any at bats.”

Meanwhile, with UCLA’s R column at one and H column at two in the first inning, Dugger added a single H that added four Rs.

It was the backstop’s second grand slam in six games.

After having just three longballs and 25 RBIs in 58 games as a sophomore, the junior already has two home runs and 17 RBIs through 19 games.

“Sticking to the approach that coach Ward (assistant coach Bryant Ward) gives us has been a huge help,” Dugger said. “Just him helping my mental game on the hitting side – that’s grown a lot – but also just getting older and growing.”

Though there are columns for runs, hits and errors – the E of R-H-E – that trio doesn’t include hit by pitches.

UCLA had eight – tied for its most in a single game since at least 2016.

“It’s a big part of our game as a team,” said junior second baseman Phoenix Call. “We do anything to get on base. … No one’s really afraid of getting hit by a pitch.”

Call got plunked twice – but also notched two singles for his second multi-hit game of the season through seven starts, his first of which came March 3.

Call began the season injured, dealing with a flexor strain in his right forearm, he said.

While on the sidelines – or in the dugout, rather – Call seemed to serve as the designated chest-bump guy on the Bruins’ home run celebration.

But back on the diamond, the chest bumps are still going strong – with junior shortstop Roch Cholowsky leaping into Dugger on the latter’s grand slam Friday – and Call is back to doing his secret handshake with Cholowsky after the throw down to second in between innings.

However, Brennan’s run-rule walk-off did cut one act from the evening’s show – the backflip Call performs at second base when the Bruins hold on for a win in the field.

“We used to do backflips, me and my cousins … like 10 years ago,” Call said. “But we just recently started doing it as a tradition – me and Roch – after a game last year.”

Maybe, someday, someone will add a backflip column to the scoreboard.
