Chicago Cubs fans might look back on the seventh inning of Tuesday night’s game at Pittsburgh’s PNC Park as the inning that finally put the fork in their 2019 season. It wasn’t surprising that Adam Frazier, the ex-Mississippi State standout, played a lead role for the Pirates in that pivotal frame, starting the seven-run inning with a double and capping it with an RBI single. The Pirates, shut out by Kyle Hendricks to that point, rolled to a 9-2 victory that snapped their nine-game losing streak and extended the Cubs’ losing skid to seven. One more Cubs loss or one more Milwaukee win will officially eliminate Chicago from playoff contention. “It just went away, brother. It went away,” said Cubs manager Joe Maddon, who might be nearing the end of his tenure. Frazier, who took over as the Bucs’ regular second baseman this season, has been flourishing down the stretch for a team that long ago fell out of the playoff race. The lefty hitter, a sixth-round pick out of State by Pittsburgh in 2013, has batted .353 over his last 30 games with three homers, 16 RBIs and 18 runs. Frazier is batting .281 with 10 homers (matching his career-high) and 49 RBIs on the year. He has set career marks with 32 doubles, seven triples and 77 runs. He is eligible for arbitration after this season and should get a nice raise. P.S. Brian Dozier, the former Southern Miss standout, enjoyed a celebration Tuesday with the Washington Nationals, who swept two from Philadelphia to capture a National League wild card berth. Dozier, who went 1-for-3 in Game 1, will be in the postseason for the third straight year and with a third different team (Minnesota, the Los Angeles Dodgers and the Nats). He is hitting .233 with 19 homers this year.
