In Todd Helton's last 10 games, he is batting .412. That is a stretch of 14 hits in 34 ABs, with 9 runs scored, 2 homers, 8 RBI, 9 walks and only 2 Ks. In 2001, Helton faced Moyer for 2 ABs in which he scored 2 runs, hit a double and drove in a run.
The Official site mentions that Josh Fogg is 6-3 in interleague play. But Moyer is having a great June with a 3-1 record and a 2.06 ERA.
It'll be a tough matchup considering that most have not faced Moyer yet. I think he winds up with a no-decision and the Rockies win with an 8th inning RBI double.
