PHOENIX -- For as long as Kurt Suzuki was around, the A's would come into spring training knowing what they had behind the plate.
Now, not so much.
Derek Norris has power that Suzuki never did. John Jaso is an on-base machine in a way that Suzuki never was.
But neither brings the defense, nor the game-calling savvy, that Suzuki did for four full seasons and parts of two others before being traded to the Washington Nationals in August.
Few teams can afford their catchers to be offense-only players, however, and the jury is out on the defensive skills Norris and Jaso bring to the mix. Much of spring training will be devoted to having manager Bob Melvin, a former catcher, see what he likes in each man.
For the moment, Melvin is looking at a modified platoon system that would see the left-handed Jaso, 29, get more at-bats than the right-handed Norris. But that's not a long-term solution in Melvin's eyes, because he sees the 24-year-old Norris eventually catching 130 games per year.
"It's going to be interesting to see how it plays out," Melvin said. "Both guys bring a lot to the table."
The scouting report on Jaso: Offensively. he takes pitches, hits for a decent average and has a career .359 on-base percentage. Defensively he has an average arm and gets credit for calling a good game. But he has problems with balls in the dirt, of which there were plenty in Seattle.
He's been behind the plate for two of the better pitching staffs in the game in Tampa Bay and Seattle.
"The guys here are going to like throwing to him," said A's closer Grant Balfour, who was teammates with Jaso in Tampa Bay. "In Tampa they wanted him to work on blocking balls in the dirt, and he did it, really took it in stride. He's put himself in a really good position here."
The scouting report on Norris: Offensively, he has 20-homer potential, but in his big league debut last season, after a .333 average in his first eight games, he hit just .179 the rest of the way, so he has yet to prove he can hit major league pitching. Defensively, he has an average throwing arm but compensates with a quick release, so he can be difficult to run against. More than anything, the A's pitchers like throwing to him.
"He's going to be a decent defensive catcher one day," one American League manager said. "But he's got work to do. You could see his improvement from the time he got called up to the end of the season. And you can't overlook what he did as a rookie, dealing with a really good pitching staff."
Jaso had to fight his way into the lineup last year in Seattle, wedged as he was between veteran Miguel Olivo and rookie Jesus Montero. By the time the season was done, the Mariners were finding any excuse possible to keep his bat in the lineup.
"He gives you a good at-bat every time," Seattle skipper Eric Wedge said. "You can't underestimate how important that is."
Jaso and Norris might be competing for playing time, but their competition also is about collaboration. They already have spent time talking about the Oakland pitchers and what it will take to get the most out of what appears to be one of the deepest and best staffs in the big leagues.
"I know he wants to play every day; so do I," Norris said. "I know I can't be thinking in terms of playing in a platoon.
"For me, it's about continuing to develop the trust I want the pitchers to have in me. I want them to trust that I will not let any ball they throw get by me. I want them to know they can throw the ball to any extreme and I'll get to it."
There are other catchers in camp, notably Luke Montz, who has been hitting some monster shots in batting practice. But look for Jaso and Norris to get the bulk of the time behind the plate when Cactus League play starts.
And as much as Melvin wants offensive production out of his catcher, he's going to lean heavily toward the better defender.
