My selection is on Kansas City over Arizona at 9:40 pm et on Tuesday.

The D'Backs shook off the jet-lag following an eight-game road trip to deliver a 9-6 win over the Royals last night. I look for Kansas City to answer back on Tuesday. Yes, the Snakes have their best starter on the hill in Zac Gallen on Tuesday. He'll be making his second consecutive start on just four days' rest, however, and it might be tough to be completely focused here against a lowly interleague opponent in the Royals. Note that Arizona continues to give up a lot of runs. It has allowed 5+ runs in eight of its last nine games. The D'Backs are still just 11-11 at home this season, averaging only 3.5 runs per game while being outscored by 0.3 runs on average. The Royals check in off five straight losses and certainly want to salvage something from this two-game stop in Arizona before an off day followed by a four-game set in Minnesota. Rookie starter Jon Heasley has run into a couple of tough lineups in his first two starts this season, the Rangers and White Sox. In two career road starts he has given up just one earned run in 8 2/3 innings of work. Finally, we'll note that even after last night's win, the D'Backs are still just 2-11 in their last 13 interleague home games. Take Kansas City (8*).
