(B365) Burrows has been perfectly average with a SwStr% higher than any of Kirby’s in 2 of his 3 starts. Kirby 8.2%, 6.7%, 5.9% being masked by 21.6 K%. His 5.8% Barrels/BBE masking 51.9 HardHit%. Most of hard contact on ground (59.6 GB%), but just .204 BABIP. Kirby seems off, but does have far superior pitch modeling than Burrows though. However, both below average defensive lineups and HOU offense crushing (148 wRC+ Rd, 150 v RHP, 132 L7 days – not counting Sunday). F5 to stay away from pens. (Would play to +135)

HOU +145
