(Reuters) - Phil Mickelson, in his 2015-16 PGA Tour season debut, carded a pair of late bogeys to end the first round of the CareerBuilder Challenge in La Quinta, California four shots back of Indian co-leader Anirban Lahiri.

Mickelson, a five-times major winner making his first start since last October's Presidents Cup, picked up six strokes over a seven-hole stretch from the fifth, including an eagle-two at the eighth, before a late stumble left him with a four-under 68.
