DraftKings MLB: DraftKings Plays and Strategy for Monday, April 29
April 29, 2024
The Blue Jays are facing 27-year-old Jonathan Bowlan in his second career start, making Vladimir Guerrero Jr. and company a great stack option for your DraftKings lineups.
2024 Fantasy Outlook
Bowlan made his major league debut in 2023 making two appearances and throwing just three innings in late September. The 27-year-old compiled an unimpressive 5.91 ERA, 1.58 WHIP and 105:45 K:BB over 102 innings between Double-A and Triple-A. With the additions of Seth Lugo and Michael Wacha this offseason and it's difficult to envision a rotation spot for Bowlan heading into 2024. The right-hander's best path to a roster spot could be out of the bullpen, though he's only been used as a reliever seven times in his career across all levels. Bowlan is unlikely to hold much fantasy value outside of spot starts.
