PITTSBURGH -- The Pirates’ next general manager is going to have to figure out the club’s immediate future and long-term plan behind the plate. Francisco Cervelli is gone. Elias Díaz, once a well-regarded prospect, followed up an encouraging 2018 campaign with a stunningly poor season. There isn’t a catcher among the club’s Top 30 prospects, according to MLB Pipeline.

It’s entirely possible that Pittsburgh’s next starting catcher isn’t currently on the roster. But part of the solution might have emerged amid the disappointment of this past season.

Jacob Stallings spent the past four years as the Pirates’ third or fourth option at catcher, which means he’s familiar with the road between Pittsburgh and Triple-A Indianapolis. But this season, Cervelli’s concussion and Díaz’s struggles opened the door for Stallings to receive more regular playing time.

Stallings’ offensive performance was fine, especially compared to the Pirates’ other catchers. But the 29-year-old earned the club’s trust with his diligent preparation and his performance behind the plate. By the end of the year, most of Pittsburgh’s starting pitchers had asked to work with Stallings.

Where that leaves Stallings going forward is anybody’s guess. Maybe a new GM will view him as a short-term starting option for a team focused on the future or perhaps as a spiritual successor to Chris Stewart: a quality, defensive-minded backup on a potential contender.

Before looking forward, though, let’s review Stallings’ season.

What went right?
His defensive work, primarily. It’s tough to quantify everything about catchers’ defense, but Stallings graded out well in the areas we can measure and those in which we depend upon the word of his teammates.

Stallings has long been praised by pitchers for his preparation and game-calling, and that showed this year. By late May, Chris Archer worked exclusively with Stallings. Joe Musgrove soon followed suit. Most of Trevor Williams’ and Mitch Keller’s starts down the stretch came with Stallings behind the plate.

Catcher ERA is a flawed statistic in some regards, but it can paint part of the picture here. Consider how Pirates pitchers performed when throwing to Stallings (4.47 ERA), how similar that was to their work with the veteran Cervelli (4.42) and how different it was with Díaz behind the plate (5.95).

There are more advanced metrics to consider, too.

Stallings ranked eighth among all Major League catchers in adjusted Fielding Runs Above Average, according to Baseball Prospectus, and 11th in Framing Runs. The latter was a focal point for Stallings this season, as he committed himself to the skill of framing pitches with former bench coach Tom Prince and bullpen catcher Jordan Comadena.

Stallings did all the necessary drill work, catching weighted balls and properly positioning his body behind the plate and his glove around the strike zone. He watched video of elite pitch-framers and noticed how well they were able to keep their gloves in the zone, rather than letting the ball move them, so he strengthened his body in the weight room.

“It’s been a continual growth process. I feel like I’ve gotten a lot better as the year’s gone on,” Stallings said in late September. “It’s been more this year than ever in the past.”

What went wrong?
This is not a knock on Stallings, but the answer is probably his games played total (71) and the fact that he had more plate appearances (210) than Cervelli.

Stallings started 53 games for the Pirates this year, which is not how you draw it up for your third catcher leaving Spring Training. Díaz started 75 games behind the plate despite having a brutal year overall, and Cervelli made 32 starts before he was sidelined and later picked up by the Braves.

Offensively, Stallings was more or less who he’s always been. The 29-year-old batted .262 with a .325 on-base percentage and a .382 slugging percentage. The good news is he tapped into a little more power to hit six home runs, as many as he’s ever hit in a professional season. He credited hitting coach Rick Eckstein for that improvement.

“Working with him, learning about my body and my swing,” Stallings said. “Pulling the ball in the air with backspin was something I struggled with. I used to always just topspin the ball because I wasn’t putting myself in a good position to hit. I really dove into that. It’s something that I will always struggle with because I’m so big and lanky with a lot of moving parts, but body position to hit has been the biggest change for me this year.

“I feel like I have a good swing. I just don’t put myself in position to hit all the time. So we worked a lot on that, and it’s something we always have to work on. Putting myself in a more consistent position to hit has helped a lot.”

Best moment
How about June 27, when Stallings had three hits and a homer and caught a shutout against the eventual American League champion Astros in a 10-0 Pirates win at Minute Maid Park?

Or how about the Pirates’ September series in San Francisco? Stallings hit two of his six homers in a historically pitcher-friendly ballpark while catching a pair of victories.

2020 outlook
Stallings is under club control, so he should be back in some role. But will the next management group take another shot on the upside Díaz showed in 2018?

There are plenty of free agents available, and the Pirates picked up recent contributors like Cervelli and Stewart through smart trades. How would that decision or another acquisition affect Stallings? Stay tuned.
