Houston at Colorado

Houston stayed UNDER for the fourth game in a row with its 2-1 win over Colorado on Tuesday. There have been a total of only 14 runs scored by both teams in that span as the Astros have relied on terrific pitching, allowing only eight runs their last seven games. The Rockies have stayed UNDER four of their last five games and have scored just two runs in their last two games with the Astros. Rookie right-hander Ryan Castellani has a 1.04 ERA in two starts and has struck out 10. And he allowed one run in 4 2/3 innings against the Rangers on Friday. Framber Valdez has given up five earned runs in 23 2/3 innings for Houston for a 0.68 ERA. The Astros are 20-5-1 UNDER their last 26 interleague road games versus right-handed starters. Take the UNDER.
