“Baseball’s fun.” Brett Phillips, the former Biloxi Shuckers outfielder and hero of Game 4 of the World Series, threw out that little pearl in his breathless postgame TV interview Saturday night. Baseball can be gut-churning and soul-crushing, too, because one team has to lose. That’s how it works. But at its core, baseball is a kids’ game — and it’s fun. How could Game 4 be described as anything else? Filled with twists and turns, capped by a crazy walk-off play, three images will endure: Tampa Bay’s Randy Arozarena, who scored the winning run, lying in the third-base line, slapping home plate with his hand. Phillips, whose two-out hit set in motion the game-deciding play, imitating an airplane in the outfield as his exhuberant teammates chased after him. Dave Roberts, the Los Angeles Dodgers manager, looking out incredulously at the scene from the dugout railing. Game 4, an 8-7, series-squaring win for the Rays, featured six home runs, including a tape-measure blast by ex-Mississippi State star Hunter Renfroe. There was some clutch pitching, too, as a parade of arms went to the bump. There was some good defense — Renfroe was credited with two outfield assists and Mookie Betts made another athletic snag — and there was the shaky D on the final play, where a bobble, a hesitant relay throw and a whiffed catch allowed the winning run to score. It’s a best-of-3 now. Game 5 is tonight. It’s gonna be fun.
