Two years after defecting from Cuba to Mexico, Triple-A Norfolk outfielder Dariel Alvarez is one of the Orioles' rising position prospects, combining a steady glove in the outfield with an electrifying plate presence.

Down to their final out, the Orioles finally came though with men on, as Matt Wieters hit a two-out, two-run single in the 10th inning to deliver a 4-3 comeback win in front of an announced 23,653 at Camden Yards.

The Orioles traded for right-hander Scott Feldman just more than two months ago to fortify their starting rotation. They believed the veteran they acquired from the Chicago Cubs would be a valuable asset in their chase for a playoff spot.

Wolf, released by the Milwaukee Brewers Aug. 22, was added to the 40-man roster, which didn¿t require a corresponding move. He is expected to be used primarily out of the bullpen.

Right-hander Jason Hammel tied a career-high with 10 strikeouts, allowing just two earned runs on six hits as the Orioles beat the White Sox, 5-3, Thursday to win their second straight road series. After winning three of four on Chicago¿s South Side, the Orioles head west to Anaheim to complete a three-city, 10-game road trip that began with two wins in three games in Toronto.

The Orioles are interested in trading for the White Sox's Gavin Floyd and Carlos Quentin. The Orioles, known to be seeking pitchers and an outfielder, have spoken with the White Sox "several times" at the winter meetings, according to Dan Duquette.
