The bullpens at Citizens Bank Park have a new feature: protection from the elements — and taunting fans

The Phillies returned home to Citizens Bank Park on Monday to a revamped ballpark.

Some of the new features include an LED screen behind the backstop, a new LED ring around the suite level, an Xfinity logo above the batter’s eye in center field, and a glass fridge in the Phillies dugout. One of the biggest changes, however, is a new enclosed space in the bullpens.

The Phillies relievers had a chance to briefly check out their new digs during their stop in Philadelphia before they headed to Washington for opening weekend. But the bullpens were still under construction at the time, so Monday marked the first time experiencing the full extent of the changes.

Tanner Banks thinks the new space will help stave off the elements, which is key for a position in which warmups are crucial.

“I thought about that last year, hot day games, or early in the year when it was cold, what’s the secret to staying warm without throwing 10 layers on?” Banks said. “So I think from a performance standpoint, and just overall, the feel of the bullpen will be a lot better.

“It’s hard to get warm when it’s 35, 40, even 45 degrees and windy, so that’ll be huge. Or stay cool. Those July day games are hot.”

The doors open up accordion-style, so their view of the field isn’t impeded. And on nice days, the entire space can stay open.

On the flip side, the visiting team now has a place to avoid taunts from fans.

“It was only fair,” Banks said.

Banks didn’t get much heckling as a visitor to Citizens Bank Park with the White Sox, due to the lack of divisional rivalry and their low place in the standings. But the away bullpen can be a hostile environment for teams like the Braves and Mets, with Phillies fans only a few feet above.

Rob Thomson expects visiting teams to keep the bullpen doors shut the entire year.

“That’s probably what I would do,” he said.

Trea Turner, who missed the final two games of the Washington series after experiencing a back spasm, was out of the starting lineup again on Monday. However, he came in to pinch-hit in the seventh inning of the home opener.

With left-handed reliever Scott Alexander on the mound for the Rockies, Turner came in for Brandon Marsh. Thomson’s decision paid off: Turner worked a six-pitch walk, and ultimately came around to score on a double from Edmundo Sosa. He was replaced in the lineup by Johan Rojas, who took over in center field.

Turner, who thinks the back problem stemmed from a hip issue during the final few days of spring training, is feeling better and took ground balls on the field before the game. He also hit in the cages.

Catcher J.T. Realmuto missed Sunday’s game with a bruised left foot, but was back in the lineup on Monday.
