Mike Aviles, SS – It would be a good idea to grab Aviles and start him during the four-game series at Camden Yards if you're looking for a shortstop that's potentially available in your league. Since being recalled from Triple-A Omaha in late May, Aviles has performed well enough to become the everyday shortstop for the Royals. He is hitting .321 with three home runs, 14 RBIs and 16 runs scored in 23 games this season. Although he is only 3-for-17 in his past four games, Aviles could provide a spark for your fantasy team if he has a good series against the Orioles. Royals center fielder David DeJesus is Kansas City's hottest hitter – .361 batting average, four home runs, 19 RBIs and 18 runs scored in June – but he left the series finale against the Cardinals in the second inning after bruising his ribs in a collision at home plate. He's listed as day-to-day, but he should be in your lineup if he's able to play.
