Travis Buck, Henry Rodriguez, John Meloan promoted; Chris Carter unlikely to get call

With Triple-A Sacramento having been knocked from the playoffs last night, the A’s promoted outfielder Travis Buck and relievers Henry Rodriguez and John Meloan.

This is Rodriguez’s major league debut. Meloan, 25, was claimed off waivers from Pittsburgh on Sept. 2, and Bob Geren said he’ll fill a middle relief role similar to what Jeff Gray is doing right now. He’s made seven career appearances in the majors, split between the Dodgers and Indians. “He’s a control guy, not a flame thrower, but good command,” Geren said of Meloan.

One player we probably won’t see in Oakland is first baseman Chris Carter. Geren said it’s “highly doubtful” Carter or anyone else will be added to the big league roster before season’s end. Carter enjoyed as fine an offensive season as anyone in the minors, but the A’s obviously want to keep evaluating Daric Barton at first base. So Carter probably wouldn’t have gotten regular at-bats. “He’s had a great season and he’s going to be forcing his way into the picture, just not at this moment,” Geren said.

Buck, who seemingly has slipped down the totem pole in the A’s outfield picture, said he was pleasantly surprised to get word of his call-up. With Rajai Davis and Ryan Sweeney playing so well, his innings might be limited. And when he does play, I’d expect it to be in left field to spell Scott Hairston.

Rodriguez is the most intriguing newcomer. You’ll remember he impressed in 2008 spring training with his 100 mph fastball, but his big-time strikeout totals in the minors have been countered by a high number of walks too. Rodriguez, 22, was hindered in spring training with his recovery from offseason hernia surgery, and his back also has bothered him. Geren said he’ll look for low-pressure situations to ease Rodriguez into.

It’s another right-handed dominated lineup for the A’s, with Davis again in the leadoff spot. Adam Kennedy gets another day off, but Geren said he’s inclined to keep Kennedy in the top spot when he plays. Ryan Sweeney’s knees are doing better, but Matt Carson gets another start in his place.
