What It Means:

Johnson will fill in for Doug Fister, who had his start pushed back to Thursday after being called in for relief during a 16-inning marathon on Saturday. The 26-year-old southpaw has gone 2-0 in four other starts for Boston this season, including a complete game shutout of the Seattle Mariners on May 27.

In the majors this season, Johnson owns a 4.29 ERA, 1.27 WHIP, and 18.5 strikeout percentage across 21 innings. numberFire's models project him to score 25.2 FanDuel points at a cost of $6,600 tonight versus the Blue Jays, but his upside could be limited by a 1.082 park factor in Boston.
