Adam Frazier may have found his form, and his discovery comes at a good time. Former Mississippi State standout Frazier delivered a go-ahead RBI single in the eighth inning Friday night for Pittsburgh, capping a three-hit game in the Pirates’ 7-6 win against St. Louis. Frazier’s clutch knock came on a 101 mph sinker from Cardinals gas-thrower Jordan Hicks. “It says a little bit that I’m where I need to be if I can do that on him,” Frazier told mlb.com. Frazier hit .301 in 66 games as a rookie in 2016 and followed that with a strong 2017: .276, six homers, 53 RBIs, 55 runs, six triples, nine steals. But he struggled out of the gate this season and was sent to the minors in June. He made a brief return to the Bucs, went back to Triple-A Indianapolis again and then got another call on July 25. He has 10 hits since, lifting his average to .269 with three homers and 11 RBIs in 66 games. Frazier is a lefty hitter who can play practically anywhere, which, if he continues to produce at the plate, makes him a valuable piece for Pirates manager Clint Hurdle. The old Jackson Mets skipper has guided this overachieving club to 17 wins in its last 22 games and into the thick of the playoff chase in the National League. P.S. Still searching for his form is ex-State star Chris Stratton, whose return to San Francisco’s rotation on Friday did not go well. The right-hander from Tupelo allowed five runs in the first inning and six all told in three innings of work as the Giants fell to Arizona 6-3. After a good start this season — he was 6-3 through May — Stratton wobbled and wound up back in the minors for a stint. He has been knocked around in both appearances since his return and is now 8-7 with a 5.52 ERA. His spot in the rotation may be in jeopardy.
