Lee went 3-for-4 with a double and three RBI in Sunday's 6-1 win over the Athletics.
Lee knocked in half of the Astros' runs with an RBI single in the fifth inning and a two-run double in the seventh. The 23-year-old catcher had gone 0-for-4 with a walk in his first three big-league games, making one start in that stretch. With veteran Martin Maldonado around, Lee's playing time is likely to be limited to one or two starts a week, though an extended stretch of good hitting could help Lee force his way into the lineup more often while Jason Castro (knee) is out.
