PITTSBURGH -- Jake Mangum went 3 for 4 with his first homer of the season and a go-ahead RBI single after the Pirates blew a six-run lead as Pittsburgh held off the Minnesota Twins 10-9 on Saturday. Mangum went deep against Bailey Ober (6-3) in the second inning for the fourth home run of his career. He later tagged Ober with a line drive single in the fifth that scored Konnor Griffin to help the Pirates steady themselves after the Twins erased a massive early deficit. Mangum also contributed defensively, going deep in the gap in left-center to rob Minnesota's Orlando Arcia of extra bases in the ninth with the tying run on first. Gregory Soto got the final four outs for his seventh save. Yohan Ramirez (3-2) earned the win in relief after starter Mitch Keller couldn't hold an early 7-1 lead.
