Neil Dexter made an unbeaten 73 as fortunes fluctuated on day one of Middlesex's LV= County Championship fixture against Somerset in Taunton.
Club captain Dexter helped the visitors escape from a vulnerable position at 211/7, putting on 48 with Toby Roland-Jones, but Somerset may still feel the happier of the two sides at 293/8 on a traditionally high-scoring ground.
Middlesex had earlier made a strong start through in-form openers Sam Robson (42) and Chris Rogers (57), and looked set to post a big total when number three Joe Denly joined in the free-scoring with a crisp 55.
But impressive 19-year-old fast-bowler Jamie Overton removed both openers on his way to 4/65 and Middlesex also struggled against the ledt-arm spin of former Cardiff MCC University bowler Jack Leach.
Dexter will be key to taking Middlesex beyond 300 on day two, and captain Rogers will have confidence in an attack which features new signing James Harris for the first time since he picked up a hamstring injury in the opening match of the season.
