Mancini went 2-for-2 with two walks, two doubles and two runs scored in Friday's 10-3 win over the Orioles.
Mancini started his career in Baltimore and spent his first six seasons there before being traded to Houston last year. The slugger appeared locked in from the start versus his former team and reached safely four times for the first time this year. It was also the first time Mancini had recorded multiple extra-base hits in a game and third time he worked multiple walks. The 31-year-old had fallen into the short side of a platoon at first base, but with Matt Mervis now back at Triple-A, a hot streak could propel Mancini into a prominent role.
