CLEVELAND — For the third consecutive game and the fourth time in the last seven games, Bob Melvin had both of his catchers in the starting lineup Friday.
Derek Norris was behind the plate and John Jaso was the designated hitter.
The problem is that Melvin doesn't have anybody behind them in case of injury. Well, there is third baseman Josh Donaldson, who was a catcher as well as a third baseman as he tried to break in with the A's, but Melvin doesn't want to have to use Donaldson.
Until Friday, the A's had first baseman Daric Barton as an emergency catcher, but the club designated Barton for assignment in order to clear a roster spot for Kyle Blanks, a first baseman and outfielder acquired from San Diego.
Melvin said playing both Jaso and Norris at the same time gets him thinking about what could happen.
"I don't like to talk about it,'' he said. "I hope we don't get into that position.''
On the other hand, Jaso and Norris are thriving of late. Jaso has a five-game hitting streak and has scored at least one run in each of those games. He's 10-for-21 in that span with three homers, two doubles and seven runs scored.
Norris was 1-for-10 in the series against Chicago, but that was the first blip on his radar in quite a while. He's hitting .352 for the season, the second-best average in the American League among players with at least 75 at-bats. Over his last 19 games, he is averaging .415 with 11 walks, making for a .516 on-base percentage.
Donaldson hasn't caught in a big league game since 2012, during which time he has become one of the best third basemen in the game, and Melvin doesn't want to have to risk that by putting him behind the plate.
--Melvin said the acquisition of Blanks to be the platoon first baseman with Brandon Moss could impact the number of at-bats that Alberto Callaspo gets.
Callaspo had been the A's right-handed option at first base against left-handed starting pitching, but that role is being ceded to Blanks. Callaspo remains the backup at second base and third base.
"I'm thinking about it,'' Melvin said when asked if Callaspo could push himself into the starting mix at second base, a position where Eric Sogard and Nick Punto have been manning the fort.
