Tale of two debuts: Oswalt struggles, Happ shines

Roy Oswalt and J.A. Happ each debuted for his new team on Friday night. Oswalt struggled against the Nationals, allowing five runs (four earned) in six innings as the Phillies lost 8-1. Happ was much more effective against the Brewers, allowing just two hits in six innings as the Astros won 5-0.

Oswalt's curveball is normally his out pitch, but in his first start for the Phillies it wasn't as effective as normal.

  • Allowed two extra base hits against the curve (had only allowed two all season).

  • Had no strikeouts with the curve for just the 3rd time this season.

  • On the other hand, Happ put up some of the better numbers in his career in his first start for the Astros.

  • Brewers missed on one-third of their swings, a career-high for Happ.

  • Recorded season highs with six strikeouts, 13 swing-and-misses and 12 swings on pitches outside the zone.

  • Allowed no hits in 10 at-bats ending with a fastball.

  • Will things get better for Oswalt down the stretch? He has struggled greatly against the NL East during the 2010 season. In seven starts against the other four teams in the division, Oswalt has gone 0-4 with a 5.93 ERA while allowing opponents to hit .328.
