It's easy to understand why the oddsmaker has put up such a high total for this matchup at Coors Field. The Blue Jays rank third in homers and there have been six straight overs at Coors with the average combined run total in these last six games being 15.6 runs. The Rockies are the third-highest scoring team in the majors and rank fifth in homers.

But there is much to like about going under starting with the wind blowing in at about 10 mph. Both teams have their best starting pitchers going - Marco Estrada versus Jon Gray.

Estrada has gone six-plus inning allowing five or fewer hits in 11 straight games. He leads Toronto with a 2.70 ERA. The under is 22-7-1 in Estrada's last 30 starts.

The Rockies are likely to be missing their starting middle infield of DJ LeMahieu and Trevor Story. Both were injured Sunday. LeMahieu is batting a team-best .327 and Story has hit 19 homers. There is a huge drop-off to their weak-hitting replacements.

The Blue Jays, remember too, are minus injured Jose Bautista.

Gray is the Rockies' most promising pitcher. He had a streak of five quality starts in a row until he left with arm fatigue during his past start. He's been cleared for action here.
