Kyle Freeland (2-10, 5.19 ERA, 1.52 WHIP, 70 strikeouts); Orioles: Dean Kremer (8-7, 4.06 ERA, 1.25 WHIP, 94 strikeouts) BOTTOM LINE: The Baltimore Orioles host the Colorado Rockies to begin a three-game series.

The Rockies have received a recent boost from second baseman Adael Amador, who has gone 5-for-9 in three games since being recalled from Triple-A Albuquerque. That's far better than the production the 22-year-old rookie provided during a stint with the big-league club in April and May.
