The winner, above, of this week’s Sunshots theme, “Sports action,” is Colleen McCloskey with her tack-sharp photo of a rugby player scoring a try at the collegiate Rugby Championship in Chester, Pa. This image was shot with a Nikon D500 at 170mm, f2.8, and 1/1600 sec.

Baltimore Sun photographer Algerina Perna observes: “McCloskey caught the player at the critical time just a split-second before scoring.

The player’s determined expression coupled with his body suspended parallel to the ground emphasizes the intensity of the score and makes a compelling image.”

Kevin Moore is this week’s runner-up, right, for his photo of a volunteer playing “Bull Hockey” at the Battle of the Beast rodeo near Union Bridge.

Moore took this image with a Canon 5D MKII at 85mm at f.4. Perna comments: “The photo captures the peak action of the rider flying vertically above the bull while the animal kicks up dust with its legs. The expressions of the handlers and spectators illustrates the excitement of watching the unusual scene.” Submit your photos This week’s category is “Historic.” Send us your photos on this subject, and we will display the best online and in print on Sunday, Sept. 10.
