Corey Dickerson, the former Meridian Community College star from McComb, has been called up by the Colorado Rockies. Dickerson, an eighth-round pick in 2010, was batting .386 with nine homers, 19 doubles, 13 triples and 38 RBIs at Triple-A Colorado Springs. The left-handed hitting outfielder is not in the starting lineup for tonight’s game at Washington. P.S. Roy Oswalt’s first pitch was clocked at 92 mph. Strike one to Denard Span. Oswalt, in his 2013 debut for Colorado, would strike out Washington’s leadoff batter and 10 more Nationals on Thursday night. Oswalt had life on his fastball, and the Rockies, from all indications, were encouraged by the performance. But, of course, the right-hander from Weir and Holmes Community College did give up nine hits, including a homer, a triple and two doubles, and four earned runs in five innings. And he took the loss as the Rockies fell 5-1 at Nationals Park. The jury’s still out on what kind of impact Oswalt will have for the Rockies. It’ll be most interesting to see how he fares in his first start at hitter-friendly Coors Field, which likely will come during a June 28-July 4 homestand. Some MLB Network analysts suggested Oswalt’s stuff might not be well-suited to Coors.
