Colorado at Arizona

Arizona needs to salvage a win from this three-game series and it has won 22 of Zack Greinke's last 30 home starts and five of his last six starts overall.  Greinke is 10-5 with a 3.18 ERA and he has allowed only seven runs his last six starts in 38 innings pitched. The right-hander is 4-1 with a 2.56 ERA at home this year and he comes off 7 2/3 shutout innings in a 3-0 win at Atlanta on July 14. Also, Grienke has walked only six batters his last six outings with 34 strikeouts. Antonio Senzatela has been activated from the disabled list due to a finger injury and he gave up six runs in six innings his last start at Seattle. Senzatela has a 7.20 ERA on the road and 7.59 in day games. He faced Arizona once and allowed two runs on three hits in 2 2/3 innings. Play the Diamondbacks.
