White Sox, Frazier enjoy walk-off win over Mariners

Todd Frazier has been an all-or-nothing threat with 31 homers and a .211 batting average and an even lower average (.159) with runners in scoring position. In the White Sox’ 7-6 victory over the Seattle Mariners Thursday at U.S. Cellular Field, Frazier came through with something other than the long ball – a tying two-run single in a three-run seventh inning and a walk-off RBI single in the ninth.

Tim Anderson, with nine hits in his last 23 at-bats since returning to the second spot in manager Robin Ventura’s lineup was 3-for-4 including an RBI double in the seventh plus a sacrifice in the ninth that put Adam Eaton (2-for-4, three runs) on second base for Frazier, who lined a single down the left field line against Nick Vincent after Jose Abreu (2-for-4, eight-game hitting streak, 15^th RBI in last 19 games) was intentionally walked. Abreu, Avisail Garcia and Dioner Navarro had RBI in a three-run first against James Paxton.

“To come up clutch felt pretty good,’’ said Frazier, who was 0-for-4 with four strikeouts against Vincent previously. “It would have stunk if I didn’t get the job done, but for me it felt pretty darn good to get it done.’’

David Robertson (4-2) pitched a scoreless ninth, working around a lengthy delay caused by two fans – and then a third after the first two were done – running around the outfield.

“The first two guys I was like, ‘OK they have it under control,’ ” Robertson said. “The next guy, I got a little angry there.’’

Sox players had better luck surrounding Frazier in their postgame celebration than ballpark security had halting the intruders.

“Everybody played hard,’’ Robertson said. “We didn’t give up at all tonight.’’

The Sox improved to 61-65, dropping the wild card contending Mariners to 67-60.

Sox right-hander Anthony Ranaudo allowed six runs and five hits in 5⅓ innings.

Narvaez catches Sox attention

Left-handed-hitting rookie Omar Narvaez, 24, who has hit safely in 11 of the 12 games he has started at catcher, has ‘‘opened some eyes,’’ general manager Rick Hahn said. Narvaez was playing in Class A last season.

‘‘He has really acclimated himself well in the big leagues,’’ Hahn said. ‘‘He has put himself on the map for the next several years of playing some sort of role on this club going forward.’’

Wait till next year?

Hard-throwing right-hander Zack Burdi has excelled and progressed all the way to Class AAA Charlotte since the Sox picked him 26th overall in the June draft, but he isn’t a lock to be called up in September, Hahn said.

‘‘He’s got a world of ability,” Hahn said, alluding to Burdi’s 100 mph fastball and good slider. ‘‘Whether it’s in September or it’s next year, it’s not too far away that he’s going to be able to help our big-league club.’’

Trainer’s room

Center fielder Austin Jackson (knee surgery) and third baseman Matt Davidson (surgery on broken foot) have made progress but won’t return this season, Hahn confirmed. Jackson signed a one-year, $5 million deal during spring training in hopes of carving out a better position in the free-agent market this winter.
