Welcome To The Show: Jase Bowen got the full Jhoan Duran Experience in his MLB Debut

The Phillies’ bullpen was flawless Tuesday night. Alvarado, Kerkering, Keller, and Jhoan Duran combined for four shutout innings after Nola left. Four arms, four zeros, a clean handoff from the starter to the closer without a single moment of panic.

That’s been the standard under Mattingly. The bullpen that was a liability during the 9-19 start has become one of the most reliable units in baseball since the managerial change.

Duran closed it out by striking out the side in the ninth in a one-run game. Three up, three down, all punchouts. The man throws 97 mph splitters and sweepers that fall off a cliff. When the game is tight and Duran is on the mound, it’s over.

Opposing hitters know it. The crowd knows it. The Phillies know it. Having a closer who can put away a one-run game by striking out the side is the kind of luxury that keeps this pitching-first formula alive.

Jase Bowen Had the Worst Welcome to the Big Leagues Imaginable

Padres outfielder Jase Bowen made his Major League debut Tuesday night. The kid was planning to take his wife to the airport Monday morning. She had a flight to catch. Before they left, Triple-A manager Pete Zamora called and told Bowen to pack his own bag. He was going to Philadelphia. The big leagues.

You dream about that phone call your entire life. You imagine what the first at-bat will be like. You picture yourself stepping into the box at a Major League ballpark, hearing the crowd, seeing the field under the lights.

You don’t picture stepping into the box in the ninth inning of a one-run game against Jhoan Duran throwing 97 mph sweepers that move like they’re controlled by a PlayStation joystick.

Fair to say Jase Bowen facing Jhoan Duran with the game on the line in his MLB debut was a bit of a mismatch…

Three pitches. Three sweepers. Three swings. Three misses. Each one progressively further off the plate. Look at the pitch locations. The first one was on the outer edge of the zone. The second one was a ball off the plate.

The third one was damn near in the other batter’s box. Bowen swung at all three of them because when Duran’s sweeper comes out of his hand, it looks like a strike until it’s three feet from where you thought it was going to be. By the time your brain registers that the pitch is unhittable, your bat is already halfway through the swing.

Could have told me that was Nick Castellanos up there and I would have believed it. Three sweepers, each one further off the plate than the last, swinging through all of them. That’s just Duran being Duran against a kid who 24 hours earlier was planning his wife’s ride to the airport and had no idea he’d be standing in the box at Citizens Bank Park with the game on the line against one of the nastiest closers in baseball.

Welcome to the show, Jase. It gets better. Probably. Maybe. Actually, facing Duran in your first big-league game might have been the worst part of your career and everything is uphill from here. That’s the optimistic take.

At Least The Phillies Bullpen Has Become a Weapon

The bullpen conversation has completely flipped since April. During the 9-19 start, the relief corps was blowing leads, walking guys, serving up homers, and making every close game feel like a coin flip. Under Mattingly, the bullpen has been one of the best in baseball. Alvarado has settled in. Kerkering is reliable. Keller has been solid in the middle innings. Duran at the back end is a cheat code.

When the Phillies’ starters give them five or six quality innings and hand the game to the bullpen with a lead, the lead holds. That’s the formula. Starter goes deep, bullpen locks it down, offense provides just enough.

It’s working because the pitching on both sides of the equation is performing at an elite level. Tuesday night was the latest example. Nola gave them five solid innings, the bullpen gave them four scoreless, and Duran ended it by embarrassing a rookie who deserved a gentler introduction to the Major Leagues.

The Phillies’ pitching staff is carrying this team on its back. From the rotation to the bullpen, every arm is contributing. The offense is barely holding up its end of the deal but the pitching is so dominant that it doesn’t matter most nights. Duran striking out the side in the ninth of a one-run game is exactly why.

Tough break for Bowen. Even tougher break that his first taste of the big leagues was three unhittable sweepers from a guy who was literally the worst possible matchup for a debut.
