The Bonus Points
The winger completed 80% of his 41 passes, in addition to a goal and an assist following a deflected shot off Cherries defender Steve Cook (£5.1m).
Pedro's BPS tally of 41 was the highest of any midfielder in Monday's matches and meant he earned three bonus points.
That edged out team-mate Eden Hazard (£10.4m), who scored 40 in the BPS.
The Belgian claimed a goal from the penalty spot and completed 13 dribbles and 85% of 56 attempted passes.
Hazard lost out on the maximum three bonus points because he was tackled on four occasions.
Gary Cahill (£6.3m) picked up the single bonus point on offer as Chelsea earned a fourth successive clean sheet and their eleventh of the season.
The centre-back completed 96% of his 51 passes and made six recoveries.
The Scout Notes
Pedro's third double-figure tally of the season failed to ignite FPL interest as the Spaniard picked up his fifth yellow card.
He will now serve a one-match suspension in the Gameweek 19 visit of Stoke City to Stamford Bridge.
Costa is already the top transfer target ahead of Friday's 7pm GMT deadline, attracting more than 29,000 new owners.
