St. Louis at Arizona

Arizona will try to salvage a split in this series as Rubby De La Rosa takes the mound after allowing only one run on three hits in six innings against Pittsburgh on Saturday. The right-hander has settled down after a poor performance against the Cubs in his first start of the season and he has 18 strikeouts in 16 2/3 innings. Michael Wacha is 2-0 and has been blessed with good run support with St. Louis scoring 25 runs his last three starts.  He allowed two runs in six innings st San Diego in his last outing but with no strikeouts. Wacha has given up one earned run at home in 12 innings but also allowed six earned runs in 10 1/3 innings on the road. The value is with the home underdog in this matchup, so back the Diamondbacks.
