Overview
- Alex Smalley seized the solo lead Friday, posting a 69 to reach 4 under through 36 holes at Aronimink.
- Scottie Scheffler shot a 1-over 71 after three early bogeys and sits at 2 under, two shots off the pace in his title defense.
- Chris Gotterup carded the low round of the week with a 65, and Hideki Matsuyama added a 67, moving both to 3 under and into striking range.
- Rory McIlroy, who opened with a 74, began his second round with early birdies as he fought to reach a projected cut near 3 over.
- Cold, gusty wind on the Donald Ross layout punished misses and kept scores tight, following Thursday's record start that left 48 players within three of the lead.
