Home runs were the dominant theme in the MLB playoffs on Wednesday night. There were 14 in the three games, and a couple of postseason homer records were set. Unfortunately for former Ole Miss star Lance Lynn, he was on the bad end of one of those records. The 36-year-old right-hander, starting for Los Angeles, allowed four solo homers in the third inning, accounting for all of Arizona’s scoring in a 4-2 win that clinched a National League Division Series sweep for the upstart Diamondbacks. No team had ever hit four homers in one inning of a postseason game. “The way (Lynn) was throwing the baseball, I didn’t expect that,” Dodgers manager Dave Roberts told the Los Angeles Times. Maybe it shouldn’t have been a total shock. Lynn led all of MLB with 44 homers allowed this season, which he split between the Chicago White Sox and the Dodgers. And the ball flies at Arizona’s Chase Field. Lynn — described by TBS’s Ron Darling as “stubborn, angry and mule-ish” on the mound — got through the first two innings, allowing just two singles. Then … boom: 1,626 feet of home runs in the third. Lynn was gone after 2 2/3 and the Dodgers, the No. 2 seed in the NL, were gone from the postseason a little while later. Lynn has had a great career. He won an SEC title at Ole Miss and a World Series title with St. Louis. He has made two All-Star Games. He has won 136 major league games, five more in the postseason, and he won a World Baseball Classic game earlier this year. But that four-homer inning is no doubt gonna sting for a while. … Elsewhere, Philadelphia hit a club-record six homers, two by Bryce Harper, in a 10-2 win over Atlanta at another homer haven, Citizens Bank Park. The Phillies lead that NLDS 2-1 heading into Game 4 tonight. Former Mississippi Braves standout Spencer Strider, a 20-game winner this year, will start for the Braves. … Houston clinched its seventh straight American League Championship Series appearance by beating host Minnesota 3-2 in Game 4. All the runs in that game came via the long ball, with Jose Abreu hitting the go-ahead shot — his third in the two games at Target Field — in the fourth inning.
