Chavez and Hoes join Orioles, Gregg and Adams DFA'd

The Orioles made a series of roster moves today, selecting the contracts of outfielders Endy Chavez and LJ Hoes from Triple-A Norfolk and designating reliever Kevin Gregg and second baseman Ryan Adams for assignment. Chavez was expected here today, and Adams was my guess to be removed from the 40-man roster. However, the Orioles changed their plans with Hoes after Nick Markakis suffered a broken left thumb. Chavez batted .190/.222/.281 with two home runs and eight RBIs in 47 games with the Orioles earlier this season. He was designated for assignment on Aug. 4 and batted .149/.192/.213 in 15 games with Norfolk. Hoes, a third-round pick in the 2008 First-Year Player Draft out of St. John's High in D.C., will be making his major league debut. He batted .300/.374/.397 with three home runs, 38 RBIs and 54 runs scored in 82 games with Norfolk after beginning the season with Double-A Bowie, where he batted .265/.368/.372 in 51 games. He's wearing No. 71. Gregg went 3-2 with a 4.74 ERA in 40 appearances for the Orioles this season. He allowed six runs (seven earned) in his last five games over 4 1/3 innings. The Orioles will absorb the remainder of the $5.8 million on Gregg's contract for this season. They held a $6 million option for 2013. Adams, a second-round pick in 2006, batted .224/.312/.353 with four homers and 20 RBIs in 65 games with the Tides this season.
