Three-time major champions Harrington is currently ranked 36th in the world
Padraig Harrington shot a three-under second-round 69 to continue his strong start to the Houston Open.
In the final event before next week’s Masters, the Irishman produced a mixed round but an eagle and five birdies left him on seven under.
American Chris Kirk is the early clubhouse leader on nine under, a shot ahead of compatriots Anthony Kim and Johnson Wagner.
English world number two Lee Westwood fired a par 72 to remain four under.
The 37-year-old from Nottingham made a poor start to his round, dropping three shots on the back nine as he carded four bogeys and a birdie.
However, he rallied on the way home to claim three birdies on the front nine to salvage par.
He is joined on four under by American Phil Mickelson, who continued his warm-up for the defence of his Masters title with a second successive round of 70, and Italian Francesco Molinari, who shot a 71.
Ross Fisher’s 70 meant he reached the halfway point on three under, two strokes ahead of compatriot Brian Davis and South African Ernie Els.
