Dustin Johnson has won at least one tournament every year since he has been on the PGA Tour, starting in 2008. With the 36-hole lead in the Genesis Open, he's halfway to chalking up a win in a 10th consecutive year. That's just one thing You Oughta Know going into a marathon Sunday at Riviera in Los Angeles.
• Johnson's streak is the longest active one on Tour.
• Since 1960, only two players have 10-year streaks that began in their rookie seasons: Woods and Jack Nicklaus.
• Johnson has 12 PGA Tour wins. Since 2008 only Woods (18) and Rory McIlroy (13) have more.
• With opening rounds of 66-66, Johnson is bogey-free over his last 23 holes. He has the most bogey-free rounds at Riviera - five - of any player since 2008.
• His opening two rounds gave him a total of eight rounds of 66 or better at Riviera - the most of any player since 2008.
• Johnson would ascend to the world No. 1 ranking if he wins at Riviera and current No. 1 Jason Day finishes fourth or worse. Through two rounds, Day was eight shots behind Johnson.
• Cameron Tringale's second-round 64 equaled the lowest round of the week.
• Tringale's 82-yard hole-out for birdie on the 18th hole was the longest hole-out in any PGA Tour event since 2014.
• Tied for second after 36 holes, Tringale has never finished in the top 10 in seven career starts at Riviera.
• Tringale is looking for his first PGA Tour win. He has three career runner-up finishes.
• Pat Perez, tied with Tringale after 36 holes, has three top-5 finishes in his previous six PGA Tour starts.
• Jordan Spieth, who won last week, has never won in consecutive weeks on the PGA Tour.
• Spieth is five shots off the 36-hole lead despite having made only two bogeys in his first two rounds.
