Phil Mickelson might be new to the PGA Tour Champions series, but the 50-year-old is apparently feeling right at home.
Mickelson leads the field in the Charles Schwab Series at Ozarks National after carding a 10-under 61 to open the tournament Monday. David McKenzie is one shot back in second, while Tim Petrovic, Rod Pampling, K.J. Choi and Rocco Mediate are tied for third at seven under.
The five-time major champion birdied No. 1, setting the tone for a blistering round. His best stretch came on the back nine when he birdied five straight holes.
