A look at the Orioles' Dominican Summer League All-Stars and other minor league notes

Two players from the Orioles organization played in Sunday's Dominican Summer League All-Star Game. They were on the South team that lost 9-7 to the North. Ricardo Andujar, a 21-year-old switch-hitting shortstop from Azua, Dominican Republic, got the start and went 1-for-3. Victor Romero, a 19-year-old right-hander from Los Teques, Venezuela, retired the only hitter he faced. Andujar is batting .358 to rank seventh in the DSL in 37 games for the O's DSL-1 team. Andujar has a .455 OBP, a .460 slugging percentage, 10 doubles, two triples, no homers, 10 steals and 12 RBIs. He is batting .435 in 12 games this month. Romero is 0-2 in eight starts, but has the fifth-best ERA in the DSL at 0.88. Over 41 innings for the O's DSL-2 team, he has allowed 30 hits with eight walks, 34 strikeouts, a 0.93 WHIP and a .199 average against. O's Dominican hitting coordinator Ramon Caraballo was a coach in the All-Star game. The Orioles DSL-1 team has the second-best record in the 36-team DSL at 30-12 (.714) and is in first place in its division by four games. That club has the best team ERA in the league at 2.62. The Orioles' DSL-2 team is 17-25. In his first four games since moving to Triple-A Norfolk, first baseman Christian Walker is 5-for-12 (.417). He has two doubles and three RBIs and is 4-for-6 with three RBIs his last two games after going 1-for-6 his first two. Outfielder Dariel Alvarez is batting .267 (4-for-15) in his first four Norfolk games. Alvarez has one double and two RBIs, and has one hit in each of his four games for the Tides. Meanwhile, outfielder Mike Yastrzemski is batting .353 (6-for-17) in his first four games for Double-A Bowie after going 0-for-5 Sunday. Yastrzemski has two doubles, a triple and a .977 OPS. Norfolk lost 14-2 to Rochester on Sunday to snap the Tides' six-game winning streak. Norfolk is 11-2 in its last 13 home games. Norfolk was attempting to pick up its first four-game home series sweep of Rochester since 1969, when the Tidewater Tides swept a four-game set from the Wings at Frank D. Lawrence Stadium in Portsmouth, Va. Left-hander Tim Berry, the Orioles' No. 6 prospect according to Baseball America, pitched seven scoreless innings for Double-A Bowie Sunday in a 3-0 win at Altoona. Berry, now 5-5 with a 3.65 ERA, gave up just three hits in his first scoreless start for the Baysox. Right-hander Oliver Drake picked up his 23rd save in 25 chances in that win. Drake is 2-1 with a 2.39 ERA. Over 37 2/3 innings, he has walked 13 and fanned 47 for Bowie. The Single-A Frederick Keys were nearly no-hit on Sunday. Winston-Salem's Tony Bucciferro lost the no-hitter with one out in the ninth at Harry Grove Stadium when Glynn Davis singled. The Dash won 5-0 to snap Frederick's three-game win streak. Quick trivia question: Which Delmarva pitcher leads both the South Atlantic League and O's minor league system in strikeouts? Most are going to say that one is easy, it's Hunter Harvey. But it is Harvey's teammate, 22-year-old lefty Mitch Horacek. Horacek got a no-decision Sunday in Delmarva's loss to Hagerstown. The Orioles' ninth-round pick in 2013 out of Dartmouth is 5-8 with a 3.34 ERA for the Shorebirds. Over 102 1/3 innings, he has walked 23 and fanned 112. He has 30 strikeouts in 21 innings this month. Catcher Austin Wynns and third baseman Drew Dosch have 13-game hitting streaks for Delmarva. Wynns is batting .452 in 12 games in July and Dosch is batting .343 in 18 games this month. Among a few members of the Orioles' 2014 draft class doing well at short-season Single-A Aberdeen are fifth-round pitcher David Hess out of Tennessee Tech and ninth-round infielder Austin Anderson from the University of Mississippi. Anderson is batting .327 in 14 games. Hess is 1-1 with a 0.96 ERA over four games. In 9 1/3 innings, he's allowed six hits with three walks and seven strikeouts. The O's minor league records: * Norfolk is 44-58 * Bowie is 52-49 * Frederick is 45-51 * Delmarva is 54-46 * Aberdeen is 10-25 * GCL Orioles are 9-15
