On Mark McGwire night at Pfitzner Stadium last night, the Potomac Cannons and the Lynchburg Hillcats combined for four home runs, including a grand slam by Potomac's Andy Bevins, as the Cannons (11-16) defeated the Hillcats, 6-2, before a crowd of 3,547. The Cannons are the St. Louis Cardinals' affiliate in the Class A Carolina League.

Right-hander Finley Woodward, who was named the Carolina League pitcher of the week, improved his record to 5-6 and left-hander Larry Wemberly dropped to 5-1. After Freddy May led off the first inning with a home run for Lynchburg (17-13), Bevins hit a grand slam in the bottom of the inning to give Potomac a 4-1 lead.

Rob Macrory opened the inning with a line drive up the middle and Jack Wilson followed with another base hit. With runners on first and second, William Ortega pushed a soft bunt down the third-base line to load the bases. With no outs, Bevins worked the count to 3-1 before ripping his home run to right field.

"I knew he was going to throw a fastball," Bevins said. "He threw it about belt high and I got a pretty good piece of it."

The blast was his third grand slam of the year, his fourth home run this week and a league second-best 20th home run of the season.

"Home runs seem to come in bunches," Bevins said. "We haven't been able to give [Woodward] much support this year, but when a few guys get started, it all runs pretty smoothly."

In the bottom of the fifth, Wemberly gave up a homer to Ortega -- his sixth off of Hillcats' pitching this season. David Kim doubled in the sixth, and scored on Brad Freeman's base hit to left field to secure the win. Jose DeLeon got his third save.
