Ah, the thrill of victory and the agony of defeat. Mississippians experienced both on Friday — and something in between, as well — in the wide world of big league baseball. Start with the agony. In the big Houston-Oakland showdown, former Mississippi Gulf Coast Community College standout Tony Sipp, an Astros reliever, surrendered a walk-off home run to Matt Olson that gave the A’s a 4-3 win in 10 innings and cut Houston’s lead to 1 game in the American League West. Sipp has been very good this season. His ERA entering Friday’s game was 1.50. He hadn’t allowed a run since June 24. He hadn’t allowed a home run all season. So, yeah, that one hurt. On to the thrill: Mitch Moreland, the Mississippi State product, is also having a helluva year — and so is his team, the Boston Red Sox, who have the best record in the game. They trailed early on Friday against Tampa Bay in Fenway Park but rallied, going ahead to stay in the fifth inning on an RBI hit by Moreland, his 62nd RBI of the year. He scored a run in the seventh inning as the Red Sox, 87-36 and 43-15 at home, stormed to a 7-3 win. Meanwhile, at Yankee Stadium, ex-Ole Miss star Lance Lynn, who had been lights out in his first three appearances for New York, gave up four runs in the first inning against Toronto but his personal agony was erased by a thrilling Yankees rally. They won a rain-shortened affair 7-5, staying within shouting distance — if only barely — of the Red Sox in the AL East. Lynn now has a 2.61 ERA in four games, three starts, with the Yanks since arriving in a trade with Minnesota.
