Shane Bieber allowed two earned runs over five innings Tuesday in a Cactus League start against the Dodgers.

Bieber had surrendered just one run over 14 spring innings coming into this one. Both runs Tuesday came on solo homers in the bottom of the fourth. The 23-year-old right-hander still pitched pretty well overall, striking out six batters without issuing a walk. He boasts a 1.42 ERA and 23/2 K/BB ratio over 19 innings in this year's Cactus League and is shaping up as an excellent mid-to-late round fantasy value for the 2019 regular season.

Shane Bieber struck out eight batters over five no-hit innings against the Rockies in a Cactus League start on Thursday.

Despite uncharacteristically issuing a pair of walks ---- his first free passes of the entire spring -- Bieber was literally un-hittable for five frames. Perhaps the most impressive part of his entire performance was that five of his eight strikeouts were called third strikes. The 23-year-old righty has given up only one run on three hits with a 17/2 K/BB ratio over 14 innings this spring. Given his pinpoint control and realistic strikeout upside, Bieber appears to be on the precipice of joining the upper-echelon class of fantasy starters this season.

Shane Bieber struck out four batters over four shutout innings in a Cactus League start against the Rockies on Saturday.

Bieber was in complete control, allowing just one hit over four frames. He also did not walk a batter. He’s allowed only one run on three hits with nine strikeouts and zero walks over nine innings of work this spring. The 23-year-old righty has become a trendy industry sleeper pick because of his extensive track record of pinpoint control (1.81 BB/9 in 114 2/3 major-league innings last year). However, the central question in his profile is whether he was around the plate too much in his brief exposure to big-league hitters, which led to consistently hard contact and a bloated 4.55 ERA. If Bieber can pitch out of the zone effectively and get hitters to consistently chase moving forward, he’s going to evolve into an elite fantasy starter.
